PHOENIX – State courts have ruled that Arizona owes public schools a first payment of more than $300 million for failing to make annual inflation adjustments to base funding as called for by a voter-approved law. Over five years, the bill could be $1.6 billion. Whether and when schools get that money may depend in large part on who occupies the governor’s office come January. Democrat Fred DuVal says the state should make the first payment. Republican Doug Ducey says he agrees with Gov. Jan Brewer’s decision to appeal the ruling, though he isn’t ruling out the possibility of a settlement.
