Pinal County AZ — County Attorney Signs Rogue 287(g), Board Declares It Illegal
The Fight
In December 2025, Pinal County Attorney Brad Miller unilaterally signed a 287(g) agreement with ICE that went beyond the existing jail-based program, effectively turning his office’s 10 investigators into ICE support staff. He did this without informing or getting approval from the Pinal County Board of Supervisors.
Why This Fight Matters
This is a governance crisis, not just an immigration fight. A county attorney bypassed the elected board to expand federal immigration enforcement authority on his own — then hired employees without board authorization or pay. The Board’s unanimous response suggests this overreach threatens the basic structure of county government regardless of where officials stand on immigration.

- April 3, 2026: Pinal County (via Snell & Wilmer) files reply seeking preliminary injunction, arguing Miller “had no statutory right” to enter the agreement
- April 9, 2026: Status conference before Judge Michael Gordon (Maricopa County).

Combined hearing on the preliminary injunction and motion to dismiss set for May 15, 2026 (Pinal County newsflash)
- April 13, 2026: AZ Mirror / Tucson Sentinel coverage — Snell & Wilmer’s reply quotes the public-interest test, arguing “the public interest does not support” county officers “acting as vigilantes outside the bounds of their appropriate, statutory authority”
- April 16, 2026: Pinal County (via Snell & Wilmer) files Response to Motion to Dismiss in Maricopa County Superior Court (case CV2026-008061, before Judge Gordon), arguing Miller “fails to point to any authority granting his office the power to enter into a contract on behalf of the County” and citing A.R.S. § 11-201(A)(3) and 8 U.S.C. § 1357(g)
- April 22, 2026: Board agenda includes executive sessions targeting the County Attorney’s Office. Miller’s office responds publicly: “We did not start this fight, but we will finish it where it belongs: in a courtroom” and accuses Board of “frivolous legal actions” (InMaricopa)
- ~April 22-24, 2026: Board votes unanimously to declare that “a potential conflict of interest exists” regarding the County Attorney’s ethical obligations to the Board and how PCAO investigators exercise law-enforcement authority. Board sets a Friday-noon deadline for Miller to respond; if he does not, the county manager is directed to hire outside counsel to represent the Board (KJZZ, April 24, 2026)
- As of late April 2026: Outside-legal-fee spending in the dispute reportedly totals ~$257,000 (KJZZ, InMaricopa)
- May 1, 2026: Additional filing in Pinal County case CV2026-003106 (Pinal County document portal)
- May 15, 2026 — RULING: Judge Michael Gordon rules from the bench against Miller, finding he had no power to unilaterally enter the federal 287(g) program. Gordon holds the Pinal County Attorney’s Office is not a “political subdivision” under Arizona law, so it cannot enter intergovernmental agreements on its own; only the county (via the Board) or the sheriff is authorized. The agreement is “determined to be void.”
- May 18-20, 2026: Coverage and analysis (Tucson Sentinel, KJZZ “a lawyer explains why”) underscore the structural holding — a stand-alone county officer cannot bind the county to a federal IGA.
- May 28, 2026: Per AZPM, Miller has not filed an appeal, so Gordon’s ruling stands as a final judgment in full force. Miller publicly states he is “disappointed” and “strongly considering an appeal.”
- June 2, 2026 (news check): No appeal filed and no new docket activity surfaced in the ~5 days since May 28; Miller’s status is unchanged (“strongly considering an appeal”). The void judgment remains final and in force.
The Outcome and Why It Matters
This is a win for democratic accountability. The court did not rule on immigration policy; it ruled on structure — that a single elected county officer cannot unilaterally pull county personnel and resources into federal immigration enforcement over the objection of the elected Board. The “not a political subdivision” holding is the load-bearing finding: it forecloses the workaround of routing 287(g) authority through a county attorney’s office rather than the sheriff or the board. If Miller does not appeal (none filed as of May 28), the precedent in Arizona is that rogue-officer 287(g) deals are void from inception.
The Brady List Investigator
Miller’s chief of investigations and ICE liaison, Richard “Hank” Mueller, has a documented history:
- 2009: “Multiple red-flag issues and questions of veracity” in personnel file at Pinal County Sheriff’s Office
- 2010: Forced entry into innocent couple’s apartment at gunpoint on false assumptions
- 2012: Drunken altercation, punched a patron, attempted to flee. Resigned rather than face termination.
- 2016: Participated in using an invalid warrant to enter a disabled man’s home. Officers Tasered and beat the man; city settled the resulting lawsuit.
- Currently on Arizona’s Brady list — prosecutors must disclose his problematic history to defense attorneys
Having a Brady-listed officer as the point of contact for a 287(g) agreement creates credibility problems for any immigration case his office touches.
Key Actors
- Brad Miller — Pinal County Attorney. Hired and deployed employees without board authorization.
- Board of Supervisors — Unanimously opposed. Referred Miller to AG.
- Judge Joseph Georgini — Issued the restraining order.
- ACLU — Scrutiny following the unauthorized agreement.
- Mexican Consulate in Phoenix — Issued warnings about ICE-PCSO joint operations in San Tan Valley.
Implications for the IGSA Model
If a county attorney can unilaterally sign ICE agreements over the objections of elected supervisors, it creates a template for expanding detention infrastructure without democratic accountability. This is a different vector than the Sabot Consulting sheriff-recruitment model but achieves the same end: local government resources deployed for federal immigration enforcement without a transparent public process.
