County Fight Litigation

Pinal County AZ — County Attorney Signs Rogue 287(g), Board Declares It Illegal

Pinal, AZ FIPS 04021

Vote: Board of Supervisors unanimously declared agreement illegal and void; later unanimously declared 'potential conflict of interest exists'

Current status: Active litigation in Maricopa County Superior Court before Judge Michael Gordon. At April 9, 2026 status conference, Miller agreed not to engage in ICE activities beyond information sharing during pendency of the lawsuit. Combined hearing on County's preliminary injunction motion and Miller's motion to dismiss set for May 15, 2026. Board has now also declared a 'potential conflict of interest' exists with Miller's office (April 2026). Outside legal fees reportedly ~$257,000. Miller's top investigator (Richard 'Hank' Mueller) is on Arizona's Brady list.

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.

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.
