The Arizona Court of Appeals upheld the rejection of two referendum petitions that sought to put Marana's January 2026 data center rezonings to a public vote. The petitions had circulated copies of the ordinances missing required property-description exhibits, which the town clerk had supplied. The court held that proponents must strictly comply regardless of whose mistake caused the error, leaving the rezonings in place.

Legal detail
Arizona Court of Appeals, Division Two, No. CV20260174 (decided Oct. 1, 2026, unanimous three-judge panel), affirming Pima County Superior Court. Referendum petitions on Marana Town Council's January 2026 zoning approvals for a data center project failed strict compliance (incomplete ordinance text without exhibits containing legal descriptions incl. water-rights information). Also held that only individual signers, not the committee, can withdraw signatures. Arizona Chamber of Commerce & Industry appeared as amicus.
