The Idaho Supreme Court Friday scheduled oral arguments in a lawsuit challenging the state’s new private education tax credit.

Each side will have 30 minutes on Jan. 23 to make arguments and answer questions from the court’s five justices, according to an order from Chief Justice G. Richard Bevan.

The lawsuit seeks to block the state’s first private school choice program from taking effect. In September, a coalition that includes the Idaho Education Association, the Moscow School District and advocacy groups filed a petition asking the court to declare House Bill 93’s “Parental Choice Tax Credit” unconstitutional.

The tax credit offers non-public school students up to $5,000 — or $7,500 for students with special needs — to offset tuition and other education expenses.

The coalition of plaintiffs has argued that the program violates a provision in Idaho’s Constitution that directs the Legislature to “establish and maintain a general, uniform and thorough system of public, free common schools.”

In a Friday statement, the coalition said, “We welcome the opportunity to definitively address a deeply flawed law that tries to bypass the clear constitutional mandate to establish and maintain a single, uniform system of public schools funded by taxpayers.”

Attorney General Raúl Labrador’s office is representing the Idaho State Tax Commission, the agency responsible for administering the tax credit. The Legislature also intervened in the lawsuit, hiring private attorneys to defend the legislation that Republican lawmakers passed in February.

The application period for the tax credit is scheduled to go live Jan. 15, eight days before the Supreme Court arguments.

Idaho Education News asked the Tax Commission to comment Friday afternoon, and a spokesperson didn’t immediately respond.
