Arizona schools are free to require students and staff to wear masks on campus, at least for the time being.
In a ruling Monday, Maricopa County Superior Court Judge Randall Warner said the state law banning such mandates approved by the Republican-controlled legislature at the end of June is not yet in effect.
"Under Arizona law, new laws are effective 90 days after the legislative session ends, which is Sept. 29 this year.
Warner acknowledged that there is an exception for emergency measures. But he said this does not qualify.
"They require a two-thirds vote and this statute was not approved by a two-thirds majority," Warner wrote.
