A coalition of public school advocates filed a lawsuit Wednesday seeking to block House Bill 93, Idaho’s first private school choice program. The petition will ask justices to declare HB 93’s tax credit unconstitutional and block the Idaho State Tax Commission from implementing it. The lawsuit came as no surprise to HB 93 co-sponsor Rep. Wendy Horman, R-Idaho Falls. “Private schools get taxpayer dollars without disclosing their curriculum, test scores or even requiring background checks,” Stark said during the news conference. But he said the constitutional arguments are similar to those presented in other states where challenges to private school subsidy programs were successful.
