Arizona Supreme Court

McMahan v. Grasshopper

July 30, 2026

Summary

The Arizona Supreme Court held that Grasshopper Trans, Inc. did not waive its right to challenge the entry of default because the service of process was defective and the superior court lacked personal jurisdiction when the default became effective. Consequently, the entry of default was void and the lower court's order vacating it was proper. The Court reversed the Court of Appeals decision that had reinstated the default.
