The Arizona Supreme Court is letting stand lower courts' rulings that a state voucher program to provide grants to parents of students with disabilities is constitutional.

The justices Friday without comment declined to review an October decision in which the Court of Appeals upheld a judge's 2012 ruling.

The rulings rejected opponents' arguments that the Arizona Empowerment Scholarship Accounts program violates state constitutional prohibitions on using public money to support religious or private schools.

The courts also said it is constitutional because parents have discretion on how to spend the money for education costs.

Permitted uses can include private school tuition, tutoring, required textbooks and savings for college expenses.

Challengers included groups representing school district boards, teachers and school officials.

State lawyers and advocacy groups supported the program.
