A Delaware Court of Chancery judge has refused to dismiss a lawsuit accusing state and county officials of failing to provide adequate school funding for disadvantaged students, thanks in part to outdated property tax assessments.

Vice Chancellor J. Travis Laster on Oct. 5 said that he has jurisdiction to decide whether Delaware's three counties are complying with state law requiring property to be assessed at fair market value.

In a 25-page memorandum opinion, Laster said two plaintiff groups, represented by attorneys from the American Civil Liberties Union of Delaware, had supported allegations that the counties have been ignoring the mandate for decades. While the law does not require counties to conduct assessments on any particular schedule, Laster said the court could grant equitable relief, if he finds an ongoing violation of state law.

“This court also can adapt its decree to accommodate changed conditions. Through the exercise of its equitable jurisdiction, this court will be in a position to consider the facts and circumstances, balance the equities,” Laster wrote.

ACLU attorneys sued the county finance directors in January, claiming that low-income students, children with disabilities and English language learners are not being provided with enough resources to succeed in school.

A key part of the complaint targeted the officials' adherence to a provision of the Delaware code requiring that the local portion of public school funding be based on the property's “true value in money,” which the state Supreme Court has held equates to its “fair market value.” However, property in Delaware continues to be assessed at values from three to four decades ago. New Castle County last assessed property values in 1983, and Kent County's assessment dates back to 1987. Sussex County hasn't assessed property values since 1974.

The plaintiffs did not allege any personal wrongdoing by the individual defendants; rather they sued the officers in their official capacities as property-tax collectors. The suit also named Gov. John Carney, Secretary of Education Susan Bunting and state Treasurer Kenneth Simpler as defendants.

The officials moved to dismiss the suit in April, arguing that the Chancery Court lacked subject matter jurisdiction over the complaint. The plaintiffs, they said, were essentially asking for an order compelling the counties to conduct a general assessment and should instead petition the Superior Court for a writ of mandamus.

But Laster said such a petition was not available in this case because the Delaware law does not require counties to conduct general assessments on any regular schedule. Instead, the plaintiffs had made a “classic appeal to the powers of equity,” arguing that so much time had passed since the last assessments that the current system no longer meets the mandatory value requirement.

“Because the statute does not specifically command when general assessments are to take place, only this court could grant that relief,” he wrote.

“What the plaintiffs ask for is an equitable remedy that will restore compliance with the market value requirement. What form that remedy takes will be determined after trial, based on the evidence, taking into account the equities, and after hearing from all parties. To state the obvious, the court will only reach that issue if the plaintiffs prevail.”

Delaware public schools rely on local property taxes for about one-third of their revenue, with the rest of the funding coming from state and federal sources. However, median property values in Delaware have increased 116 percent since 1980, according to Laster's opinion.

The result, Laster said, was a tax base that remains flat while operational costs continue to increase, leaving school boards to repeatedly ask voters to approve tax hikes in a series of special elections.

“Confronted with regular requests for tax increases, some residents naturally infer that school officials are wasting money. Community resentment does not help the public schools or disadvantaged students,” he said.

The ACLU has said the funding gap particularly impacts disadvantaged students, whose standardized test scores, the organization said, fall well below the state's own benchmarks.

According to the lawsuit, 64 percent of low-income students, 85 percent of English language learners and 86 percent of students with disabilities did not meet the state standards in grades three through eight for English language arts. At the same time, 74 percent of low-income students, 81 percent of English learners and 89 percent of students with disabilities fell below the state's math standards in those grades.

Among other things, the plaintiffs are seeking permanent injunctions compelling the officials to “establish, fund and maintain a general and efficient system of free public schools that provides all disadvantaged students.”
