Although sometimes difficult to detect, governmental power abuses can have detrimental impacts. Property tax assessments provide an effective lens to examine this phenomenon because, given the complexity of calculating property tax assessments, it is difficult for citizens to know when local government has exceeded its legitimate taxing authority and crossed into the realm of illegal extraction. Michigan is an ideal case study because it protects property owners by making assessment-related power abuses more visible through a unique state constitutional provision: property tax assessments cannot exceed 50 percent of a property’s market value. Abuses have persisted nevertheless. Between 2011 and 2015, one in four properties in Detroit were subject to property tax foreclosure, and inflated property tax assessments that violate the Michigan Constitution are the unseen thread in this complex tapestry of foreclosure.
Against this backdrop, this Article makes three primary contributions. First, no other article has argued and proven that property tax assessments in Detroit are illegal. Using assessment and sales data from 2009–2015 for the entire City of Detroit, we find that property tax assessments are substantially in excess of the state constitutional limit, and this illegality is most pronounced for lower-valued properties. Second, to remedy inflated assessments, in 2014 and 2015 Detroit’s assessor implemented assessment decreases ranging from 5 percent to 20 percent for select districts, but we find that systemic assessment inequity persisted for lower valued properties despite these reductions. Third, this Article uses the case of illegal property tax assessments in Detroit to develop a new theoretical concept called “stategraft,” which is when state agents transfer property from residents to the state in violation of the state’s own laws and to the detriment of a vulnerable group. Although the concept was developed using the Detroit case, stategraft applies beyond Detroit to many other cases, including the discriminatory fines imposed and enforced by the police and courts in Ferguson, Missouri; broken treaties with Native Americans; and abuses of civil forfeiture laws.
Local governments must determine the taxable value of properties in their jurisdictions, and these assessments are the basis of property tax calculations. Property taxes are a substantial source of revenue for local governments, so to protect property owners from paying more than their fair share, most jurisdictions require assessments to be uniform and/or equitable. But they are often neither. As a result, property tax assessments provide a unique and effective lens to study the larger phenomenon of governmental power abuses that are difficult for citizens to detect or defend against. This Article uses Detroit as a case study because the Michigan State Constitution goes beyond the equitable and uniform mandate, which is inexact and vulnerable to varying interpretations. Instead, the Michigan Constitution has an explicit cap on assessments that allows property owners to more easily detect assessment-related abuses. More specifically, the Michigan Constitution prohibits property assessments that exceed 50 percent of a property’s market value: “The legislature shall provide for the determination of true cash value of such property; the proportion of true cash value at which such property shall be uniformly assessed, which shall not, after January 1, 1966, exceed 50 percent . . . .” Although there have been several articles about property tax assessments in Detroit, no other article has proven that assessment practices in Detroit violate the Michigan Constitution.
More importantly, this Article uses the case of illegal property tax assessments in Detroit to develop a new concept called “stategraft,” which is when state agents transfer property from residents to the state in violation of the state’s own laws and to the detriment of a vulnerable group. Stategraft is a phenomenon that also applies beyond Detroit to various other cases, including discriminatory fines and fees levied by police and enforced by courts in Ferguson, Missouri; broken treaties with Native Americans; and abuse of civil forfeiture statutes.
Determining whether property tax assessments in Detroit are unconstitutional is an important research question for three primary reasons. First, in a typical property tax bill, the assessed value of each property is multiplied by the property tax rate, subject to various exemptions. Detroit residents endure the highest property tax rates in Michigan and some of the highest in the country. In addition, this Article shows that the majority of residential properties are unconstitutionally assessed at over 50 percent of the property’s market value. As a result, Detroit residents are being hit twice: not only are their assessed values illegally high, they are then multiplied by one of the nation’s highest rates. Many Detroiters have not been able to afford this double hit, and nonpayment has resulted in widespread tax foreclosure.
From 2011–2015, the Wayne County treasurer foreclosed on 100,116 Detroit properties for unpaid property taxes, although there are only about 384,675 properties in the city. This means that about one in four Detroit properties were subject to property tax foreclosure during this five-year period. In 2015 alone, the treasurer foreclosed on 28,158 Detroit properties. That is, in 2015, Detroit had 3,949 property tax foreclosures per 100,000 people, which is drastically higher than other cities (e.g., New York City: 52; San Francisco: 48; Los Angeles County: 8; Erie County (Buffalo), New York: 62; St. Louis County, Missouri: 197).
Since the primary economic asset of many Americans is their home, property tax foreclosure can have adverse financial impacts, but it can also have injurious emotional, social, political, and cultural consequences as well. Like many other material objects, homes exist in tandem with emotional landscapes, which suffuse them with significant intangible value. An individual’s childhood home, for instance, is often filled with memories and emotional investments such that when the home is foreclosed upon, a family loses more than an economic asset; their personhood is also impacted. Also, a house is often the basis of social belonging—a gateway to the benefits and burdens of community membership. As neighbors interact, valuable social bonds and networks are formed, and thus foreclosure often leads to social disruption. Politically, property serves as a bulwark against state encroachment on individual autonomy. Although people cannot remodel public buildings to reflect their individual tastes, walk around naked in federal buildings, or exclude others from a public parks at will, all of these activities are allowed in privately owned homes, where citizens have greater autonomy to live the kinds of lives they have reason to value. Foreclosure curtails this important source of autonomy. Foreclosure can also adversely affect cultural and identity interests. Individual and group identities are often closely tied to a particular home, neighborhood, or city, and a home, in particular, can reflect a person’s unique personality and become intertwined with her sense of self. In sum, when the state confiscates a home for nonpayment of property taxes, there are both monetary and non-monetary consequences.
Second, on average, Detroit’s residents are more economically and socially insecure than other Americans (see Table 1). Unconstitutional assessments inflate property tax bills, which can be a significant financial blow to this already vulnerable population—regardless of whether or not it causes them to lose their homes. In addition, less affluent owners are less likely to challenge property tax bills. Thus, when poorer homeowners are subject to unconstitutional assessments, these assessments are more likely to stand uncorrected. That is, invisible abuses of state power stand uncorrected. Consequently, poor homeowners—who are most unable to afford illegal and inequitable assessments—are the population that is most often subject to them.
Third, there is preliminary evidence suggesting that the unconstitutional assessments in Detroit are racially discriminatory. On July 13, 2016, the American Civil Liberties Union (ACLU) of Michigan, along with the NAACP Legal Defense Fund and the law firm of Covington & Burling, filed a lawsuit alleging that the unconstitutional property tax assessments and the resulting foreclosures in Wayne County (the taxing jurisdiction where Detroit is located) disparately impact African Americans, who constitute 82.7% of Detroit’s population. The lawsuit claims that Detroit’s assessor is unconstitutionally assessing property owners, while the assessors in Wayne County’s other jurisdictions—which are not majority African American—are not engaging in this unconstitutional behavior. Consequently, African-American homeowners “lose their homes through tax foreclosure at a higher rate than non-African-American homeowners in Wayne County,” violating the Fair Housing Act of 1968.
If the claims made in the lawsuit prove true, then unconstitutional assessments in Detroit are part of a long and sordid history of racially discriminatory property tax administration in the United States. In the Jim Crow South, officials routinely assessed property owned by African Americans at a higher proportion of its market value than they did white-owned property, leading to high property tax payments—paradoxically used to fund institutions and services that the state prohibited African Americans from accessing. Also, when their real estate became valuable or officials wanted to punish them for civil rights protest actions, one conventional mechanism for dispossessing African-Americans was to inflate property tax assessments. Unfortunately, these abuses of governmental power did not perish along with the Jim Crow South. A 2004 study of property tax assessments in New Haven, Connecticut found that in communities where African Americans and Latinos constituted the majority of residents, assessments were on average 40 percent higher than the market value of the homes. In contrast, for neighborhoods occupied predominately by white residents, assessments were on average 20 percent less than the market value of the homes.
This Article proceeds in five parts. In Part I, we examine the legal framework for assessments in Michigan. We then review the literature and discuss our methodology in Part II. In Part III, we analyze the data. Using assessment and sales data from 2009–2015 for the entire City of Detroit, we provide a dynamic view of how assessment inequity has changed during the life cycle of the housing crisis and the mayor-led, across-the-board cuts in property tax assessments, which occurred in 2014 and 2015. We find strong evidence of unconstitutional assessments across all the years studied. But assessments for lower-valued homes are substantially higher than 50 percent of their market value, while assessments for higher-valued homes are closer to this state constitutional standard. Although we offer some explanatory hypotheses in Part IV, we leave it to future research to determine the economic and political forces that brought about this pervasive unconstitutionality and why it has persisted for so long. In the short term, we recommend that Detroit place a moratorium on tax foreclosures for homes that are owner-occupied until it can ensure that it is in compliance with the Michigan Constitution. The City of Detroit must also ensure that property taxes owed by tax-delinquent homeowners are accurate. Finally, in Part V, based on the Detroit case, we develop a new concept called “stategraft.” More importantly, we demonstrate how this concept applies beyond Detroit.
I. Legal Framework for Assessments
A. The Michigan Constitution’s Assessment Provision:
The Legislative and Judicial Interpretation
By law, all taxable properties in the City of Detroit must be assessed on an annual basis by the city’s assessment division. In 1963, Michigan approved a new constitution, which drastically changed the procedure for determining the assessed value of properties. According to Article IX, Section 3 of the state constitution:
The legislature shall provide for the uniform general ad valorem taxation of real and tangible personal property not exempt by law except for taxes levied for school operating purposes. The legislature shall provide for the determination of true cash value of such property; the proportion of true cash value at which such property shall be uniformly assessed, which shall not, after January 1, 1966, exceed 50 percent; and for a system of equalization of assessments.
This constitutional provision goes on to say that property tax assessments may be even lower than 50 percent of the property’s true cash value because assessments can increase by no more than 5 percent per year so long as the property is not sold. In addition, the 1978 Headlee Amendment placed additional limits on local taxing powers, including voter approval for increases in property tax rates (also known as millage rates) that go beyond the Amendment’s guidelines.
The Michigan legislature codified Article IX, Section 3 of the state constitution in Section 211.27a(1) of the Michigan Compiled Laws: “[e]xcept as otherwise provided in this section, property shall be assessed at 50% of its true cash value.” The legislature has defined true cash value as “the usual selling price at the place where the property to which the term is applied is at the time of assessment, being the price that could be obtained for the property at private sale . . . .” The Michigan Supreme Court has declared that true cash value and fair market value are synonymous, and this is now a well-settled principle. Consequently, if Detroit properties are assessed at more than 50 percent of their fair market value, there is a direct breach of the state constitution and supporting legislation.
It is also well established that assessors are allowed to use diverse appraisal methods to determine a property’s market value. The legislature did not designate a specific valuation method for determining a property’s true cash value, and so the task of determining which approach is most appropriate for any given context has fallen to the Michigan courts. As the Michigan Supreme Court explains, “[a]ny method for determination of true cash value which is recognized as accurate and reasonably related to fair market valuation will fill the statutory prescription and is an acceptable indicator of true cash value.”
The courts have recognized three standard approaches: (1) the cost-less-depreciation approach, (2) the sales-comparison or market approach, and (3) the capitalization-of-income approach. More importantly, the courts have made clear that whichever approach is used, “[t]he ultimate goal of the valuation process is a well-supported conclusion that reflects the study of all factors that influence the market value of the subject property.”
For appraisals of residential housing, the industry standard is the market approach, which determines a property’s true cash value by analyzing recent sales of comparable properties. This approach requires assessors to adjust the sale price of comparable properties, taking into consideration factors such as the property’s size, age, condition, location, existing use, zoning, natural assets, and present economic income. One potential drawback of the market approach is that, in certain instances, the sale price might not be the “usual selling price” due to factors personal to the parties. For instance, it is not uncommon for parents to transfer property to their children at discounted rates. Nevertheless, when the assessor considers the sale prices of numerous comparable properties, she reduces the likelihood that factors extrinsic to the properties will impact price calculations.
In addition to having a robust sample of properties, the law requires assessors to include only arm’s length transactions—which is when there is a willing buyer and a willing seller and, thus, the sale price reflects the demand and supply for property in the market. There is, however, an exception for instances where auctions are the “common method of acquisition” for properties in the area. Although our data show that auctions have become a common method of acquisition, our estimates rely only on arm’s length transactions so that they are as conservative as possible. Consequently, we use arm’s length residential sales transactions alongside assessment data to determine whether Detroit is complying with the state constitutional mandate to assess each property at no more than 50 percent of its market value.
B. The Michigan Constitution’s Assessment Provision:
The Historical Origins
Several state constitutions require property tax assessments to be uniform and equitable. But, by requiring that assessed value/market value ratio not exceed 0.5, Michigan’s constitution is one of the few to use an explicit assessment ratio to constrain its local governments. Our review of every state constitution shows that Louisiana, Mississippi, Oregon, New Mexico, Oklahoma, and Tennessee are the only other states to constitutionally require localities to assess properties at a specified fraction of their market value. Given that these types of constitutional provisions are uncommon, how did this cap on assessed values end up in the Michigan constitution?
The historical evidence suggests Michigan’s constitutional drafters feared that without a specific constitutional provision, localities would abuse their powers and inequitably assess properties. One delegate from the 1962 constitutional convention—which was charged with drafting Michigan’s current state constitution, enacted in 1963—wrote, “[w]ell, there was very widespread distrust of the Legislature and people said, ‘leave it up to the Legislature and nothing will be done or it will not be done right. Let’s put it right in the Constitution and then we know the matter will be taken care of.’” Thus, the very purpose of the Michigan Constitution’s explicit mandate that property tax assessments cannot exceed 50 percent of a property’s market value was to prevent local governments from abusing their discretionary powers.
Michigan’s prior (1908) constitution required localities to assess all properties at full cash value, but according to Barlowe:
Wide variations exist in the extent to which assessors abide by this provision. Assessment data studies conducted in recent years show that some properties are assessed at as little as two per cent of their market values while others are sometimes assessed at more than their full market sale values. Township, city, and county equalized assessments frequently represent levels of between 30 and 50 per cent of cash value.
The issue of assessment inequity was so important that the governor, John Swainson, filed a report at the 1962 constitutional convention, detailing the unanimous findings of his Special Commission on Industrial Development Legislation: assessments varied widely and resulted in non-uniform property taxes that ultimately deterred investment.
To address the well-documented assessment inequities, the Committee on Finance and Taxation introduced an amendment at the convention. According to the Committee, the state’s 1908 constitutional provision allowed the court to “simply state that since the former taxpayer is not assessed in excess of 100%, the Constitution affords no basis for relief. This unavailability of judicial relief has made the cash value standard a positive impediment to the achievement of uniform assessment.” Consequently, the Committee drafted an amendment explicitly stating that property assessments were not to exceed 50 percent of the property’s market value. The committee suggested that 50 percent was the appropriate limit because it was “currently used by the State Tax Commission,” and it said that the standard was not unduly inflexible because the legislature would still have the ability to “change the standard to reflect changes in the general price structure.” The committee set the start date for this provision in 1966, as an acknowledgment that some jurisdictions currently relied on assessments above 50 percent.
A minority faction disagreed with the 50 percent limit and crafted a counter-amendment to delete it.  The faction’s critique of the 50 percent limit was based on issues of sufficient revenue for local governments, the proper role of the legislature, and the effectiveness of the 50 percent limit in actually providing relief to taxpayers. First, the minority report predicted “devastating immediate effect on the fiscal affairs of some communities.” Second, the minority report argued that setting a fixed limit to assessment levels was not the role of the constitutional convention: “The inclusion of an arbitrary 50% limitation, statutory in nature, does not have the dignity of a mandate of the people, as does the sales tax rate limitation, expressed in a referendum.” Third, the report argued that the 50 percent level did not make practical sense. Its authors argued that just because the State Tax Commission had used 50 percent as the proper assessment level when equalizing taxes among units of government did not mean that assessments should now be limited to 50 percent. The report’s authors also argued that while using a 50 percent limit would reduce taxes for some individuals and industries, it would increase taxes for others because all assessments would be brought closer to 50 percent in an attempt to make up for the lost revenue. The counter-amendment, however, was handily defeated 84 to 43.
Today, Detroit cannot continue to ignore the clear and unequivocal limit on assessments, which withstood vigorous democratic debate to earn its place in the Michigan Constitution.
II. Literature Review and Methodology
The Minnesota Center for Fiscal Excellence estimates that Detroit properties are subject to effective tax rates of 3.82%, more than double the national urban average of 1.5%. Given Detroit’s notoriety for high property tax rates, there have been several studies examining this. We, however, specifically build upon studies exploring assessment inequity in Detroit because our goal is to determine whether the city is complying with its state constitutional mandate to assess properties at no more than 50 percent of their market values. For example, several economists have examined assessment inequity among Detroit residents using assessment and market data from 2010. They observed severe over-assessment and regressivity at levels not previously observed in the United States. In addition, Dewar et al. compared assessed values and sales prices in one Detroit neighborhood, Morningside, from 2008 to 2013. They found that although market values declined over this period, assessments did not keep pace. They also found that lower-valued homes were more likely than higher-valued homes to be significantly over-assessed during this period.
Unlike the existing literature, our study provides a dynamic view of property tax inequity across all Detroit neighborhoods over a seven-year period, and we discuss the legality of the inequities we observe. In doing so, we make three unique contributions to the existing literature. First, we examine how assessment inequity has changed through time for the entire City of Detroit. Second, in response to prior evidence of over-assessment, Detroit’s assessment office tried to remedy this by implementing assessment decreases for two consecutive years, resulting in planned assessment reductions of 5 to 20 percent for select districts each year. We examine whether systemic assessment inequity persisted despite these reductions. Third, we examine how Detroit’s inflated assessments contravene the Michigan Constitution.
The International Association of Assessing Officers (“IAAO”) has outlined the appropriate methods for analyzing assessment accuracy, and there are two major components: level and uniformity. Level refers to the overall assessment ratio, defined as a property’s assessed value divided by its market value. Two key statistics for analyzing assessment ratios are the mean and median. Given Michigan’s constitutional requirement that assessments should not be greater than 50 percent of market value, the mean and median levels of assessment are expected to be no higher than 0.5. If the ratios derived are consistently higher than 0.5, then this is reliable evidence that assessments in Detroit are systematically illegal, and the assessing officials must take corrective action.
In contrast, uniformity (also known as variability) refers to the degree to which assessment ratios have achieved horizontal and vertical equity. Horizontal equity means that properties similarly situated in terms of market value and type of neighborhood have similar assessment ratios, while vertical equity means that higher and lower priced properties have similar assessment ratios. Horizontal and vertical inequity occur when assessment ratios vary widely. There are two methods for analyzing assessment uniformity: the Coefficient of Dispersion (“COD”) and the Price Related Differential (“PRD”). The COD measures horizontal equity by quantifying the degree to which the assessment ratios deviate from the median. The IAAO considers assessments uniform if the COD is between 5 and 15 for single-family residential properties. The PRD is a measure of vertical equity. If high-value properties have lower ratios than low-value properties, the vertical inequity is termed regressive; if the opposite occurs, it is called progressive. Assessments should be neither regressive nor progressive because—although a degree of variation between ratios is expected as well as accepted—large differences result in the non-uniform and inequitable application of property tax assessments. The PRD is calculated by dividing the mean ratio by the weighted mean ratio (the total assessed value of all property divided by the total sale price). According to the IAAO, PRDs between 0.98 and 1.03 are vertically equitable while values greater than 1.03 are regressive, and values less than 0.98 are progressive.
Beyond the IAAO’s standard measures, a simple approach for examining horizontal and vertical equity is to estimate the mean, median, minimum, and maximum assessment ratios across sale price quintiles. This allows further analysis within a quintile (horizontal equity) and an examination of how ratios vary across quintiles (vertical equity). In Michigan, if the mean and median are less than or equal to 0.5 within a quintile, then horizontal equity is present and the assessments are systematically constitutional. If mean and median assessment ratios are no higher than 0.5 across quintiles, then the assessments are vertically equitable and constitutional.
Our proposed method of analysis is called an assessment ratio study (also known as ratio study or sales ratio study), which is the primary mechanism that assessors, taxpayers, appeal boards, and taxing authorities use to determine if assessments meet the legal requirements of a jurisdiction. IAAO defines an assessment ratio study as “a form of applied statistics, because the analyst draws conclusions about the appraisal of the population (the entire jurisdiction) of properties based only on those that have sold during a given time period.” If the unsold parcels are appraised in the same manner as the sold ones, then it is valid to use the statistics derived from the sales ratio study to infer appraisal performance for unsold parcels. Our evidence shows that homes selling during the period under study are comparable to homes that did not sell. For example, the average age of all improved, taxable, residential property was 81.46 years, and the average age of our trimmed 2015 sample was 81.61 years.
III. Data Analysis
Since assessments in Detroit are calculated annually and are based on property values from the previous year, we divided assessed values with prior year sales information to produce assessment ratios. That is, we match assessment data from each year (2009–2015) with sales data from the prior year (2008–2014). For properties that were sold multiple times in the same calendar year, we took the last sale in a year as the determinant of the property’s value. As a result, the full dataset includes 123,400 residential property transactions (we exclude empty lots and non-taxable properties). The breakdown of data by year can be viewed in column (1) of Table 2. Data Driven Detroit provided parcel-level information on assessed values for all Detroit properties from 2009 to 2014. We used the City of Detroit’s Open Data Portal to secure data on all property sales in Detroit from 2008 through 2014, as well as assessed values for 2015.
For several reasons, we excluded 117,214 observations from the sample, leaving a total of 6,186 arm’s length property transactions in our analysis (column (2) of Table 2). First, our dataset included twenty-two different sales terms defined by the assessor’s office, and we excluded properties that were not arm’s length transactions. Although the law states that only arm’s length transactions should be included, there is an exception if non-arm’s length transactions (distressed sales) “have become a common method of acquisition in the jurisdiction for the class of property being valued.” Given that only about 5 percent of sales from 2008–2014 were arm’s length transactions (see Table 2), there is a strong argument that distressed sales are, in fact, the common method of acquisition for residential properties in Detroit. Nevertheless, we only include arm’s length transactions so that our estimates provide the most conservative measure of unconstitutionality. Scholars who include distressed sales in their analysis will only find unconstitutionality that is markedly more pronounced because these transactions involve smaller sums.
Second, we excluded properties that were bundled and sold as a single transaction because it is impossible to determine the price of any single property within the bundle. Bundled properties are different parcels with identical sellers, sale dates, and sale prices. Third, we excluded properties that had a sale price of zero because it is unlikely that these were arm’s length transactions; we also excluded properties with an assessed value equal to zero because these are likely to be non-taxable properties.
Although excluding 95 percent of the total observations may seem extreme, this is a result of the forced auctions and other non-arm’s length transactions that have proliferated in Detroit’s distressed real estate market. In addition, we further trimmed the data in accordance with IAAO’s nationally recognized standards, which recommend trimming the sample of statistical outliers because very low or high ratios can severely distort the analysis. We show the total observations after trimming in column (3) of Table 2, and the percentage of trimmed observations in column (4). The number of observations we excluded from our sample due to outlier trimming is below the IAAO’s recommended standard of 10 percent.
Table 3 shows the mean and median assessment ratios; the COD and PRD, which measure the uniformity and variability of the ratios; and the average sale prices for each year, highlighting changing market conditions. We also include the percentage of assessment ratios that are above the 0.5 constitutional limit to evaluate the quantity of unconstitutionally assessed properties. Table 3 provides substantial evidence that Detroit assessors are unconstitutionally assessing properties in a systematic fashion. First, for properties sold between 2008 and 2014, the majority of assessments violated the Michigan Constitution: 2009 (65%); 2010 (84%); 2011 (53%); 2012 (73%); 2013 (78%); 2014 (83%); 2015 (65%). Second, data from the assessment ratio study—which is required for making inferences about properties that were not sold during the period—show that the mean and median assessment ratios are greater than the constitutionally permitted ratio of 0.5. While the 2011 and 2012 ratios are closer to 0.5, they remain statistically larger than 0.5 when the margin of error is set at the 95% confidence level. Third, the COD for each year is much higher than the recommended maximum of 15, which is evidence that assessments are not uniform. In addition, the PRD for each year is above 1.03, which is evidence of regressivity (i.e., higher-valued properties have lower ratios than lower-valued properties). Again, we see the COD and PRD for 2011 and 2012 are closer to the recommended levels, yet remain above it.
Upon examining Table 3, one question remains: Why are 2011 and 2012 closer to the constitutionally permitted ratio of 0.5 while in the other observed years the ratios suggest even greater unconstitutionality? We provide two potential explanations. For one, the assessor classified fewer sales as arm’s length transactions in 2011 and 2012: it classified 1.7% and 3.6% of the total number of transactions as arm’s length for 2011 and 2012, respectively, whereas it classified between 2.6% and 12.4% of transactions as arm’s length in the other years. Second, median sale prices derived from the assessor’s data are much higher in 2011 and 2012 compared with the surrounding years. More importantly, the assessor’s sales data from 2011 and 2012 are not consistent with sales information from Zillow market data in these years, despite consistency between the two data sets in the other years. To check our two explanations, we did a separate analysis that included sales labeled as “Review Needed,” a sales term used for transactions that the assessor did not have enough information to classify, and the number of observations and the average sale prices became consistent with the surrounding years; in addition, the average sales prices for 2011 and 2012 became consistent with Zillow market data. With the stated correction, the average assessment ratios would increase to 3.65 and 4.90 for 2011 and 2012, respectively, suggesting there was substantial unconstitutionality in 2011 and 2012.
Table 3 also provides mixed results concerning the across-the-board assessment reductions discussed by Mayor Duggan. There is no evidence of cuts in 2014 because the mean ratio increased by 10 percent. Furthermore, vertical inequity worsened as the PRD increased in 2014, while the COD declined only slightly. However, overall assessment ratios declined in 2015 by approximately 26 percent, resulting in reductions that were larger, on average, than the 5 to 20 percent reduction the mayor expected. Despite the large reductions, vertical inequity persisted as the PRD remained above 1.03 (at 2.45), and horizontal inequity actually worsened as the COD increased to 125.36 (up from 107.34).
To further explore assessment practices in Detroit, Table 4 provides simple snapshots of how assessments vary within and across sale price quintiles by showing the mean, median, minimum, and maximum assessment ratios. We highlight the average sale price of each quintile in the row labeled “Mean SP,” and the percent assessed above the constitutional 0.5 limit is in the row labeled “%>0.5”. The most important finding shown in Table 4 is that average assessment ratios decline as property values increase. That is, Detroit’s assessors are unconstitutionally assessing lower-valued properties by a substantial margin, while the assessment ratios for higher-valued property are at or even below the constitutionally permitted limit of 0.5. Specifically, the lowest-valued properties in 2009 were, on average, assessed at levels almost eighteen times larger than the constitutionally permitted 0.5 limit (8.87); middle-valued properties were assessed three times more than the constitutionally permitted limit (1.54); and the highest-valued properties were assessed below the constitutionally permitted limit (0.4). In addition to this stark evidence of vertical inequity, assessment ratios are less uniform for lower-valued property (ranging from 0.25 to 36.29) compared with higher valued property (ranging from 0.04 to 1.6), providing evidence of regressive horizontal inequity. These results are generally consistent across all years; however, for reasons mentioned earlier, 2011 and 2012 ratios are closer to 0.5.
Table 4 further explores how Detroit Mayor Mike Duggan’s across-the-board reductions in property assessments—ranging from 5 percent to 20 percent, depending on the district—affected the ratios. Table 4 provides some evidence of reductions in 2014, with mean assessment ratios decreasing in quintiles 1, 2, and 5, while reductions were higher than the mayor projected for 2015. Specifically, Table 4 shows reductions ranging from 12% to 47% in 2015, depending on the quintile viewed. More importantly, Table 4 shows that even after the reductions, the vast majority of lower-valued properties had an average assessment ratio equal to 3.29, not even close to the 0.5 level, while higher-valued properties—which already had ratios closer to the constitutionally permitted limit of 0.5—received reductions that brought assessments to an average ratio of 0.29. As a result, for quintile 1, assessed values were, on average, $18,507 above the constitutional limit, a pattern repeated in quintiles 2 ($19,900), 3 ($13,796), and 4 ($4,890). But quintile 5 was, on average, assessed below the constitutional limit by $10,881.
We use two specific properties to better illustrate how owners of lower-valued properties are bearing the undue burden of unconstitutional assessments. In the first example, the public record shows that a property located at 15455 Artesian Street sold in 2009 for $10,000; the assessor marked this sale as an arm’s length transaction. Nevertheless, the assessed value of that property in 2010 was not $5,000 (50 percent of the property’s market value), but rather $36,094, which is 7.2 times the constitutional limit. In a contrasting example, the public record shows that, in 2008, a property located at 4127 Buckingham Avenue sold for $115,000 in an arm’s length transaction. The assessed value in 2009 was $41,369, which is $16,131 below the constitutional limit.
As a final mechanism for examining assessment trends in Detroit, Table 5 highlights the changes in average assessment ratios across districts. Because it is district specific, Table 5 is the one place we see evidence of Mayor Duggan’s 2014 assessment reductions: District 2 (25%), District 3 (12%), District 7 (20%), District 9 (35%), and District 10 (24%). The remaining districts experienced persistent over-assessment with no correction. In 2015, assessments decreased between 10% and 69% for all districts excluding District 8 (40% increase).
In sum, we find that the Detroit assessor is systematically assessing Detroit homeowners at levels that violate the Michigan Constitution. Even though we argue that the 2011 and 2012 sales data were inconsistent, we nevertheless find substantial unconstitutionality using this faulty data.
IV. FUTURE RESEARCH
The lingering question is: why has the Detroit assessor’s office systematically violated the Michigan Constitution? Although this question is beyond this Article’s scope, there are four possible answers. The first hypothesis is that the assessor’s office lacked the capacity to conduct the legally required market-based annual assessments, and thus new assessments were based on non-market related, incremental adjustments to existing assessments. This makeshift method based on conjecture became completely unworkable in 2008 when property values plummeted in Detroit (See Figure 1) and the chasm between incrementally adjusted home prices and actual home prices widened sharply. While the assessor relied on Detroit residents to appeal incorrect assessments, research shows that poor people are less likely to appeal their property tax assessments; and when they do, they have lower success rates than wealthier people.
The Auditor General’s Performance Audit shows that the Detroit Assessor’s office lacked capacity to do its job properly. The report’s authors state:
As a result of our audit, we have concluded that the overall operation of the Assessments Division falls short of their goals and objectives. Moreover, guided by the State Tax Commission’s 14-Point Local Unit Review (of assessing units), we found that the Division’s assessing operations are inefficient, ineffective, and lacking in some areas of its assessing activities.
The report’s findings are jaw dropping. For instance, auditors found that about 1,700 properties were still classified as tax exempt although they were no longer owned by the city. Also, according to a representative from the Buildings, Safety Engineering and Environmental Department, over 70 percent of the tickets this department issued for blight violations were dismissed because the property ownership information it received from the assessor was incorrect. In sum, the Auditor General’s report paints the Detroit Assessor’s office as a highly incompetent, inefficient, and broken bureaucracy, lacking the capacity to fulfill its mission.
The second hypothesis is that although there are various community organizations working on the property tax foreclosure crisis, community activists were unable to hold the Detroit assessor accountable because they were unaware of the state constitutional provision or they did not have access to the data and empirical skills necessary to prove systemic unconstitutionality.
The third hypothesis is that it is easier for Detroit to raise revenues by illegally assessing residents than by legally raising property tax rates. A Michigan constitutional amendment—the 1978 Headlee Amendment—requires voter approval for increases in property tax rates that go beyond the Amendment’s guidelines. Given the property tax rate is already one of the highest in the nation, it may be challenging to get voters to approve a hike. In contrast, Wayne County reimburses Detroit for any property tax revenue that it fails to collect; in exchange, the county receives the right to collect the revenues (with penalties and interests) and to confiscate the home if payment is not forthcoming after three years of delinquency. Without this arrangement, the Detroit officials would be incentivized to legally assess residents, which would decrease revenues but increase the probability that people would be able to afford their property taxes. With this arrangement, the city has a short-term incentive to make assessments high and extract as much money as possible to fill budget shortfalls, even though this is not in the city’s long-term interest because tax foreclosure devastates neighborhoods.
A fourth hypothesis is that even when the county does not make much money from the foreclosure auction sales, the county makes significant sums of money in late fees and interest, which is supposed to go into the Delinquent Tax Revolving Fund. The Fund should be used solely for foreclosures, but Wayne County has been using the Fund to fill its chronic budget shortfalls and to recover from its recent financial emergency. Consequently, the financially distressed county has come to rely on property tax foreclosures in Detroit to stay afloat.
These four hypotheses attempt to explain why Detroit has been unconstitutionally assessing its residents, but they have not yet been empirically confirmed or refuted. We leave this for other scholars to investigate.
The findings of the study are clear: The City of Detroit is assessing homeowners in violation of the Michigan Constitution. More significantly, city and county coffers have benefitted greatly from this theft. But, in many ways, Detroit’s illicit actions are not unique. It is not unprecedented for state agents to increase state revenues using illegal means, and we create the term stategraft to describe this phenomenon. Stategraft is when state agents transfer property from residents to the state in violation of the state’s own laws and to the detriment of a vulnerable group. The term intentionally combines the words statecraft and graft or corruption. A widely agreed-upon definition of corruption is “[t]he abuse of an entrusted power for private gain,” but stategraft is different because there is no private gain. Instead, the abuse of state power primarily benefits the state itself. Statecraft is the art of conducting state affairs, but stategraft highlights instances when state agents advance the state’s financial interests by stealing from those under its authority.
The term stategraft was born from the case of property tax injustice in Detroit. Detroit assessors are state agents who imposed inflated property tax assessments on Detroit property owners, and this act has transferred millions of dollars from property owners to city and county coffers in violation of Michigan’s state constitution. There are, however, several other poignant examples of stategraft. To initiate the conversation, we will discuss three.
The first example is lands taken from Native Americans in direct violation of a valid treaty. For instance, the Oneidas once occupied about six million acres in what is now New York. Likewise, the Black Hills of South Dakota once belonged exclusively to the Lakota Sioux who considered it sacred land. In both cases, U.S. state agents entered into legally binding treaties with the tribes but then later reneged and commandeered native lands, illicitly increasing their nascent nation’s territory. That is, the state itself (not private actors) benefitted from property illicitly taken from a vulnerable group. Prior to the introduction of the term stategraft, there was no vocabulary to discuss this phenomenon.
Second, the Department of Justice (DOJ) has sued the City of Ferguson for what amounts to stategraft. The DOJ argues that Ferguson’s police have engaged in unconstitutional policing that targets African Americans and unfairly imposes civil and criminal fines on them. Instead of reining in the unlawful police conduct, the courts issued arrest warrants when the fines went unpaid, advancing the city’s financial interest and foregoing their role as neutral arbiter. It is the City of Ferguson itself, rather than individual police officers or judges, which financially benefits from the unconstitutional policing of African Americans: a classic case of stategraft.
The third and final example of stategraft is the abuse of civil forfeiture laws. These laws are meant to allow law enforcement to confiscate property obtained unlawfully and to use the proceeds in the fight against crime. Nevertheless, in many cities, civil forfeiture has been abused, and police officers illegally seize the property of people never charged or convicted of any crimes. When the opaque legal process that individuals must traverse to regain their property is more costly than the property taken, the police department often keeps the property. For instance, in 2013, the Washington, D.C. public defender service filed a lawsuit against the district on behalf of 375 car owners who shared one thing in common: the police confiscated their vehicles but did not charge them with crimes. The district court granted a preliminary injunction in the case, finding that the main plaintiff was likely to prevail on his claim under the Due Process Clause in the US Constitution. Given the constitutional violations brought to light by the suit, the parties settled the case after the City agreed to modify its forfeiture laws. More significantly, this is a classic case of stategraft because police officers abused civil forfeiture laws and confiscated cars from innocent people whose poverty rendered them unable to recover their vehicles. Most importantly, it was the police department itself (rather than individual officers) that financially benefitted from this illicit action.
This list of examples is not meant to be exhaustive; instead, the goal is to highlight the pervasiveness of stategraft, which has five principle elements: (1) state agents, (2) transferring property, (3) from residents to the state, (4) in violation of the state’s own laws, (5) to the detriment of a vulnerable group.
State agents. “State agents” are individuals or groups who use the state’s police powers to compel people to act or refrain from taking certain actions. When working in their official capacity, state agents either have the power to make laws, policies, and administrative rules, or are acting upon the explicit directions of those with the power to do so. But in their unofficial capacity, state agents promote the state’s financial interests without explicit permission from lawmakers, who either look the other way or support their actions without directly authorizing them. In Ferguson, for example, the targeting of African Americans for fees and fines was not an official written policy, but it was a pervasive practice which used the police and courts to enlarge city coffers.
Transferring property. Property includes tangible property such as money, financial instruments, real property, and personal property. It also includes intangible property like entitlements, licenses, and intellectual property. Property transfer can involve taking away the right to use, exclude, or transfer property, or taking the property itself. In the three examples discussed above, the American government took land from native Americans; the city of Ferguson took money away from its African-American citizens using discriminatory fees and fines; through civil forfeiture, many cities have taken all types of real and personal property away from people not charged with a crime; and illegal property tax assessments have led to inflated property tax bills in Detroit.
From residents to the state. For these purposes, a “resident” is anyone who is subject to the state’s police powers, even if the person is not physically within the state’s geographic boundaries. To qualify, property must be transferred from residents directly or indirectly to state accounts. For instance, land usurped from Native Americans went to U.S. federal and state governments; fees and fines charged by Ferguson enlarged that city’s coffers; and property taken through civil forfeiture benefits the law enforcement agencies that confiscate the property.
In violation of the state’s own laws. Laws include legislation, judicial decisions, administrative rules, and policies that have the power to bind residents and regulate their actions. Only the law in effect at the time the property was taken is relevant. In the examples above, police officers abuse civil forfeiture laws to illegally confiscate property, the US government abrogated legally binding treaties with Native peoples; the DOJ has argued that the City of Ferguson contravened the Equal Protection and Due Process clauses of the US constitution; and the Detroit assessor violated the Michigan Constitution’s property tax assessment limits.
To the detriment of a vulnerable group. If the state breaks a law, then ideally citizens can go to the courts, police, or other state functionaries to correct the injustice. A vulnerable group is one that occupies a subordinate position within the polity, so they are often unable to identify or resist stategraft due to limited financial resources, lack of access to justice, and inadequate information. That is, vulnerability makes groups more likely to experience stategraft and also less able to combat it when it does occur. Tax injustice in Detroit is the perfect example. Our data show that homeowners with lower-valued homes experienced unconstitutional property tax assessments at a far greater rate than homeowners with higher-valued homes. This is because people with more information and resources had the ability to hire lawyers and other intermediaries to assist with appealing their property tax assessments and averting stategraft. But due to lack of information and resources, Detroit’s established appeals process was unavailable to the most vulnerable populations.
Stategraft is a valuable concept because existing categories do not well describe this phenomenon. The most common definitions of corruption are predicated on private gain, and there is currently no concept to describe state-led theft that primarily benefits the state. Constitutional takings is a category ill-equipped to describe the phenomenon because while sometimes instances of stategraft qualify as a takings, other times they do not. For instance, while courts have ruled that certain broken treaties with Native Americans violated the Fifth Amendment’s Takings Clause, illegal property tax assessments in Detroit would most likely not qualify because courts have ruled that the state’s tax-and-spend powers do not infringe upon the Takings Clause. Courts have also ruled that civil forfeiture does not run afoul of the taking clause. Lastly, because stategraft, by its definition, involves an illegal transfer of property, the due process clauses of the Fifth and Fourteenth Amendments will always apply. Stategraft, however, is a unique type of due process violation that deserves focused analysis because when a state steals from its own citizens, this has dire consequences for a nation’s democratic foundations. Consequently, stategraft is a theoretical framework that fills an important gap in the literature. We have provided the theoretical scaffolding for the concept of stategraft, upon which other scholars can build.
Property tax assessments provide a penetrating lens into governmental abuses of power that elude detection. Given the complexity of calculating property tax assessments, it is difficult for citizens to know when local government has exceeded its legitimate taxing authority and crossed into the realm of illegal extraction. By assessing properties in violation of the Michigan Constitution, Detroit has crossed this line and is engaging in stategraft. The illegality is systemic and has persisted since 2009, which is when property values in Detroit declined precipitously. In 2014, the City of Detroit recognized the need to comply with its state constitution by correctly aligning assessments with property values. Consequently, in 2014 and 2015 Mayor Duggan announced across-the-board cuts to property assessments. Nevertheless, lower-valued properties are still assessed far in excess of 50 percent of their market value, while the assessed values for higher-valued properties have fallen below this constitutional limit.
The illegal assessments in Detroit have severe consequences, the most dire being that it has unleashed a property tax foreclosure epidemic. Based on our analysis, we recommend that Detroit place a moratorium on property tax foreclosures of owner occupied homes until it can ensure that it is in compliance with Michigan’s constitutional and statutory laws. At the very least, Detroit must ensure that delinquent taxpayers—on the verge of foreclosure—are not subject to unconstitutional tax assessments and inflated property tax bills. More significantly, we encourage the City of Detroit to begin a dialogue with its citizens about how to heal from the social, economic, and psychological consequences of stategraft.

[I]t is impossible under these conditions to assure an industry seeking to settle in this state that it will be treated equitably in the matter of property taxes. The training, technique, and skill of the assessor are so varied in this state that in some instances it has been a deterrent to new industry. Dr. Harvey E. Brazer, of the University of Michigan, an eminent authority in this field, has stated that a study of a typical Michigan county revealed that some properties were assessed at less than 2% of market value, and others were assessed as high as 175% of their sales price. In one of our large metropolitan counties we have witnessed the practice of assessing inventories at 80% of book value, machinery and equipment at 100% of depreciated value, and real property assessed at 50% of current value.”).

. The mean is calculated by adding all assessment ratios together and dividing by the total number of ratios. The median is the middle ratio in an uneven number of ratios ordered by magnitude, or the average of the two central ratios in an even number of ordered ratios. The median is less affected by extreme outliers than the mean. Id. at 13.

. See IAAO, supra note 80, at 13–14, 28–29; Hodge et al., Assessment Inequity, supra note 5, at 241.
. We recognize other IAAO-recommended measures for analyzing assessments exist, including price-related bias, weighted mean, median absolute deviation, and regression analysis. See IAAO, supra note 80, at 12–14. However, we have presented the traditional assessment performance statistics highlighted in the IAAO’s publication, id., and used in other papers analyzing assessment ratios. See, e.g., Hodge et al, Assessment Inequity, supra note 5, at 241; Krupa, supra note 2, at 565–69; Daniel P. McMillen, Assessment Regressivity: A Tale of Two Illinois Counties, Land Lines, January 2011, at 10–12.
. As outlined in the IAAO’s publication for analyzing assessment accuracy, the COD is calculated as follows: “1. subtract the median from each ratio; 2. take the absolute value of the calculated differences; 3. sum the absolute differences; 4. divide by the number of ratios to obtain the average absolute deviation; 5. divide by the median; and 6. multiply by 100.” IAAO, supra note 80, at 13 (emphasis omitted).
. While the median and mean give equal weight to each parcel in the sample, the weighted mean gives equal weight to each dollar. Id. at 13.
. Id. at 14, 17 tbl.1-3.
. Quintiles are determined by dividing the data into five equal groups according to a variable (e.g. sale prices). See Hodge et al, Assessing Inequity, supra note 5, at 247 n.13.
. We also recognize non-descriptive techniques to analyze vertical and horizontal inequity exist. Particularly, regression analysis has been the standard method for deriving causal inference with the inclusion of various control variables. For studies using alternate regression specifications for examining vertical inequity, see generally Earl J. Bell, Administrative Inequity and Property Assessment: The Case for the Traditional Approach, 3 Prop. Tax J. 123 (1984); Pao Lun Cheng, Property Taxation, Assessment Performance, and Its Measurement, 29 Pub. Fin. 269 (1974); John M. Clapp, A New Test for Equitable Real Estate Tax Assessment, 3 J.

Sunderman, Property Tax Inequities on Ranch and Farm Properties, 74 Land Econ. 374 (1998). For studies using alternate regressions with emphasis on horizontal inequity, see generally Marcus T. Allen & William H. Dare, Identifying Determinants of Horizontal Property Tax Inequity: Evidence from Florida, 24 J. Real Est. Res. 153 (2002); Brian J.L. Berry & Robert S.

Goolsby, Assessment Error in the Valuation of Owner-Occupied Housing, 13 J. Real Est. Res. 33 (1997). Although these regression techniques are not the focus of this paper, since we examine assessments through the standards set forth by the IAAO, we have analyzed each technique using various functional forms. Results are available upon request. Our findings are consistent with the results presented in this paper: vertical and horizontal inequity is present as lower-value properties are consistently over-assessed.

. Non-arm’s length transactions excluded from our study comprise the following sales terms: “bank sale,” “city sale,” “county land bank sale,” “court order,” “government transfer,” “HUD,” “land bank,” “land contract,” “create trust,” “multiple parcels,” “NEZ,” “NQ,” “death cert/estate,” “deed in lieu of FCL,” “deed of personal rep,” “family sale,” “review needed,” “sheriff/tax deed,” “investor sale,” “to bank,” and “to investor.”
. Mich. Comp. Laws § 211.27(1) (2017).
. The estimates of illegality increase substantially when non-arm’s length transactions are included. For instance, the median assessment ratio when only arm’s length transactions are included versus when non-arm’s length transactions are included: 2009 (0.79 vs. 2.69), 2010 (1.95 vs. 4.13), 2011 (0.52 vs. 2.79), 2012 (0.69 vs. 3.85), 2013 (0.91 vs. 5.41), 2014 (1.04 vs. 2.88), 2015 (.69 vs. 2.32). Mean assessment ratios are even more severe when non-arm’s length transactions are included, ranging from 2,100 to 4,300 vs. 0.53 to 3.44. See infra Table 3.
. It may seem reasonable to assign a portion of the total price to each property based on the parcel’s size and characteristics; however, unobserved factors may prevent this split from accurately representing each property. For example, a parcel with a larger house and lot may be expected to have a higher value, but the house may be in worse condition than a smaller property it is bundled with, and thus should not automatically be granted a higher price.
. The IAAO defines an outlier as an assessment ratio below the first quartile or above the third quartile by 1.5 times the interquartile range (IQR), where the IQR is the difference between the first and third quartiles. The first quartile is the median value of the lower half of the data and the third quartile is the median value of the upper half of the data (the second quartile is the median of the entire dataset). The IAAO also recognizes that ratio distributions are often skewed to the right (i.e., a greater number of high ratios may be present), so to prevent dropping a disproportionate number of high ratios, the IAAO suggests taking the logarithm of each assessment ratio prior to trimming the outliers. IAAO, supra note 80, at 12, 53. The steps for trimming outliers are: (1) locate the first quartile (i.e., median value of the lower half of the data); (2) locate the third quartile (i.e., median value of the upper half of the data); (3) compute the interquartile range (IQR) and multiply by 1.5 = (Step 2 – Step 1) x 1.5; (4) establish the lower boundary = (Step 1 – Step 3); (5) establish the upper boundary = (Step 2 + Step 3). Id. Again, our results represent conservative estimates because they only increase when we include non-trimmed transactions. Here are the mean assessment ratios when only trimmed arm’s length transactions are included vs. when non-trimmed arm’s length transactions are included: 2009 (2.52 vs. 3.52), 2010 (3.44 vs. 5.59), 2011 (0.53 vs. 40.20), 2013 (1.57 vs. 1.65), 2014 (1.73 vs. 4.18), 2015 (1.28 vs. 60.74).
. See supra Part II.
. See supra notes 86 & 89 and accompanying text (explaining the process for calculating COD and PRD).
. See infra Figure 1.
. Other years experienced increases in mean assessment ratios when “Review Needed” sales were included. However, they were not as drastic as the increases in 2011 and 2012.
. See supra notes 77–78 and accompanying text (regarding Detroit’s tax cuts).
. The reduction is calculated by using the percentage change formula: [(new value–old value)/old value]*100. In this case, the old value is 1.73 and the new value is 1.28. Therefore, [(1.28–1.73)/1.73]*100 = [-0.45/1.73]*100 = [-0.26*100] = 26% decrease.
. See supra note 106 and accompanying text (suggesting that Detroit assessor’s office likely miscategorized several arm’s length transactions in 2011 and 2012 as “Review Needed”). Only in 2012 are the highest-valued properties (quintile 5) above 0.5.
. The decrease is more than the 20 percent decrease that Duggan authorized, in part due to our sample, which captures only properties sold (a much smaller subset of the total number of residential properties in each district).
. See Mike Duggan, Mayor of Detroit, Address at a City of Detroit Press Conference (Jan. 28, 2015) (“As I said when I was campaigning, I felt like the assessments in this city were higher than the actual sales price that people could sell their house for. We made a commitment to have honest assessments. Last year, you remember most Detroiters got assessment cuts between 10 and 20 percent and we have embarked on a parcel by parcel assessment—the first one in fifty years—and that’s going to be done at the end of 2016. We are assessing each individual home. We didn’t want to wait for that parcel to parcel assessment to be done to continue to try to do the best we can to make sure our assessments are accurate. And so we are again doing significant assessment cuts for 2015.”).
. See supra note 106 and accompanying text.
. See id. at 9 (“In the City’s electronic assessing system known as ‘Equalizer,’ a property is in an ‘override status’ when its assessed value is input as a total amount, versus the system method of calculating a value based on physical property attributes and other assessment criteria. The property’s assessed value is ‘disconnected’ in the system. Assessed values in Equalizer are historical aggregate amounts, which were transferred from the previous assessing system known as ‘IPDS’ (Integrated Physical Data Systems): Of the 42 properties audited, 28 (66.7%) remain in override status; A representative in the Assessments Division estimated that 92% of the City’s parcels 387,000 [sic] remain in override status in Equalizer.”).

Rev. 1443, 1447 (2014) (“I find that reducing property tax salience makes homeowners less likely to appeal their property-value assessments, which makes it more likely that those homeowners will remain overassessed and overtaxed.

I also find that property taxes are less salient for recent homeowners with higher-priced mortgages, who are more likely to be racial minorities, immigrants, and working families with children.”); Andrew T.

Barnett, Big-War Thinking in a Small-War Era: The Rise of the AirSea Battle Concept, 6 China Security 3, 4 (2010) (“And to the extent that America eschews such responsibilities, other rising powers seeking to protect their expanding network of economic interests will inevitably step into that void—albeit with less militarized delivery systems. China may do so, but, as is now becoming apparent, it prefers stategraft to nation-building, paying upfront from its sizeable cash coffers.”); Stephen S. Wise, The Return of Roosevelt, 191 N. Am. Rev. 738, 741–42 (1910) (“When, for example, the corrupt followers of the Quay-Stone régime in the Keystone State desperately sought to avert the crushing defeat that even apathetic Pennsylvania seemed ready to inflict upon its betrayers, these masters of Stategraft rather than Statecraft brazenly utilized the name and prestige of Roosevelt in order to stave off the day of wrath.”); Art Buchwald, The Fine Points of Stategraft, er, Statecraft, Wash.

The origin of the word is from the Latin corruptus (spoiled) and corrumpere (to ruin; to break into pieces). The working definitions presently in vogue are variations of ‘the misuse of a public or private position for direct or indirect personal gain.’”); World Bank, Helping Countries Combat Corruption: The Role of the World Bank 8–9 (1997), http://www1.worldbank.org/publicsector/anticorrupt/corruptn/corrptn.pdf (“We settled on a straightforward definition—the abuse of public office for private gain. Public office is abused for private gain when an official accepts, solicits, or extorts a bribe. It is also abused when private agents actively offer bribes to circumvent public policies and processes for competitive advantage and profit. Public office can also be abused for personal benefit even if no bribery occurs, through patronage and nepotism, the theft of state assets, or the diversion of state revenues.”); Oguzhan Dincer & Michael Johnston, Measuring Illegal and Legal Corruption in American States: Some Results from the Corruption in America Survey, Edmond J. Safra Ctr. for Ethics Harv U. (Dec. 1, 2014), http://ethics.harvard.edu/blog/measuring-illegal-and-legal-corruption-american-states-some-results-safra (emphasis omitted) (“We define illegal corruption as the private gains in the form of cash or gifts by a government official, in exchange for providing specific benefits to private individuals or groups. It is the form of corruption that attracts a great deal of public attention. A second form of corruption, however, is becoming more and more common in the U.S.: legal corruption. We define legal corruption as the political gains in the form of campaign contributions or endorsements by a government official, in exchange for providing specific benefits to private individuals or groups, be it by explicit or implicit understanding.”).

(June 25, 2000), https://nyti.ms/2jL63aB (“The Oneidas, who once occupied six million acres in New York, treated with President Washington himself. But over the next century, state officials bought and sold their land, in violation of laws and court cases requiring federal approval of Indian land transfers. By 1919, the tribal land had shrunk to 32 acres. With recent gambling revenues, the Oneidas bought back 11,000 acres, and hired top legal talent to regain the 250,000 acres lost from the reservation. The 20,000 non-Indians who own some of that land say they should not have to pay the price for a failure by the state to follow the law—nor should they have to fight their own government to hold onto their cabins, farms and houses.”).
. See id. (“[T]he Black Hills of South Dakota . . . is the longest unresolved Indian land claim in the country. Promised to the Lakota Sioux in a treaty from 1868, the land was opened to white settlement after gold was discovered, leading to the Battle of the Little Big Horn. More than a century later, the Lakota won a settlement that would have given them $106 million in 1980. But for 20 years, the Indians living in the poorest county in America have refused it, holding out for the return of their sacred hills.”).
. See U.S. Dep’t of Justice Civil Rights Div., supra note 6, at 3 (“The municipal court does not act as a neutral arbiter of the law or a check on unlawful police conduct. Instead, the court primarily uses its judicial authority as the means to compel the payment of fines and fees that advance the City’s financial interests. This has led to court practices that violate the Fourteenth Amendment’s due process and equal protection requirements. The court’s practices also impose unnecessary harm, overwhelmingly on African-American individuals, and run counter to public safety.”); id. at 15 (“Ferguson’s strategy of revenue generation through policing has fostered practices in the two central parts of Ferguson’s law enforcement system—policing and the courts—that are themselves unconstitutional or that contribute to constitutional violations. In both parts of the system, these practices disproportionately harm African Americans. Further, the evidence indicates that this harm to African Americans stems, at least in part, from racial bias, including racial stereotyping. Ultimately, unlawful and harmful practices in policing and in the municipal court system erode police legitimacy and community trust, making policing in Ferguson less fair, less effective at promoting public safety, and less safe.”).
. See id. at 2–3 (“Police supervisors and leadership do too little to ensure that officers act in accordance with law and policy, and rarely respond meaningfully to civilian complaints of officer misconduct. The result is a pattern of stops without reasonable suspicion and arrests without probable cause in violation of the Fourth Amendment; infringement on free expression, as well as retaliation for protected expression, in violation of the First Amendment; and excessive force in violation of the Fourth Amendment.”).
. See id. at 3 (“Most strikingly, the court issues municipal arrest warrants not on the basis of public safety needs, but rather as a routine response to missed court appearances and required fine payments. In 2013 alone, the court issued over 9,000 warrants on cases stemming in large part from minor violations such as parking infractions, traffic tickets, or housing code violations. Jail time would be considered far too harsh a penalty for the great majority of these code violations, yet Ferguson’s municipal court routinely issues warrants for people to be arrested and incarcerated for failing to timely pay related fines and fees.”).

Describing the policy as ‘devastating for hundreds of families who depend on their cars for many of the urgent and important tasks of daily life,’ it called for higher standards of proof and the end of penal-sum fees.”).
. It can be extremely expensive to secure the return of property confiscated through civil forfeiture laws. See Stillman, supra note 131 (“Most of those detained had to pay more than a thousand dollars for the return of their cars; if the payment wasn’t made promptly, the car would become city property.”).

. This includes both documented and undocumented citizens. The tax code’s definition of “resident” is also expansive. Harry A. Shannon, III, The General Definition of Residence Under United States Income Tax Treaties, 16 Intertax 204, 206 (1988) (“Under Article 4(1) [of the 1976 Treasury Department’s Model Income Tax Treaty], a person is a resident of a contracting state if he is subject to tax in that state on the basis of his domicile, residence, citizenship, place of management, place of incorporation or any other criterion of a similar nature. ‘Person’ is defined in Article 3(1)(a) to include an individual, a partnership, a company, an estate, a trust and any other body of persons. Both natural and juridical persons can be ‘residents’ for treaty purposes.”).
. See Stillman, supra note 131 (“But civil-forfeiture statutes continued to proliferate, and at the state and local level controls have often been lax. Many states, facing fiscal crises, have expanded the reach of their forfeiture statutes, and made it easier for law enforcement to use the revenue however they see fit. In some Texas counties, nearly forty per cent of police budgets comes from forfeiture. (Only one state, North Carolina, bans the practice, requiring a criminal conviction before a person’s property can be seized.) Often, it’s hard for people to fight back. They are too poor; their immigration status is in question; they just can’t sustain the logistical burden of taking on unyielding bureaucracies.”).
