litigation — Arizona AG Kris Mayes filed Arizona v. Mullin on April 24, 2026 — fourth state in the multi-state NEPA cluster after MD, NJ, MI. The $313M GardaWorld Federal Services contract for warehouse conversion had already been stopped via federal stop-work order at least two days before the lawsuit filing. Same NEPA argument as the Hurson Maryland precedent (April 15, 2026). Warehouse sits across from a facility storing thousands of gallons of hazardous chemicals subject to Risk Management Plan requirements under the Clean Air Act. Capacity numbers fit the documented pattern: 550 in legal filings, hundreds-to-1,500 documented as planned operational density. UPDATE (Jul 1, 2026): Mayes and federal defendants filed a stipulated agreement (Jun 30) pausing all conversion work and barring any detainee housing pending completion of the NEPA environmental assessment — first concrete check on the project since the stop-work order, pending court approval.

active-opposition — Resolutions passed, ordinances restricting ICE use of county property adopted, but federal preemption likely limits enforceability on MTC-owned land. Facility still on track for Nov 2026.

active-crisis — Nanos submitted 20-page unsworn response on April 21, 2026. Board voted to delay review until May 12. ACLU records lawsuit ongoing. Recall petition active.

won — WON (May 15, 2026): Maricopa County Superior Court Judge Michael Gordon ruled from the bench that County Attorney Brad Miller exceeded his authority and that his 287(g) agreement with DHS/ICE is VOID. Gordon held the County Attorney's Office is not a 'political subdivision' under Arizona law and so cannot enter intergovernmental agreements on its own. As of May 28, 2026 Miller had not filed an appeal — the judgment is a final judgment in full force — though he said he is 'strongly considering an appeal.' Outside legal fees in the dispute reportedly totaled ~$257,000. Miller's top investigator (Richard 'Hank' Mueller) is on Arizona's Brady list.

contested — City passed an unenforceable 5-year ban; ICE purchased the warehouse ($70M+) regardless. GardaWorld's $313M/$704M conversion contract is now under NEPA litigation (see surprise-az-ice-warehouse-fight); AZ AG Mayes and DHS filed a stipulated agreement (June 30, 2026) pausing all conversion work and barring any detainee housing pending environmental review. Separately, activist Jeremy Helfgot filed a petition (~June 21, 2026) to disincorporate the City of Surprise entirely, citing council inaction — needs 70,000 signatures within 180 days of approval to force a Maricopa County Board of Supervisors vote.
