On August 2, Arizona’s highest court released a unanimous opinion explaining its March 14 rejection of several constitutional challenges to the state’s new paid sick time (PST) law. You may remember that, upon denying the requested injunction and special action relief, the Court said it would issue a written opinion further explaining its decision in due course. The August 2 opinion does just that. It discusses the constitutionality of the PST law under the Revenue Source Rule (Ariz. Const. art. 9, § 23), the Separate Amendment Rule (art. 21, § 1), and the Single Subject Rule (art. 4, pt. 2, § 13). Although informative, the opinion does not change anything for Arizona employers. The PST law remains effective and enforceable.
