This bill establishes comprehensive regulations for the operation and contracting of immigration detention facilities within the state, specifically prohibiting contracts with private corporations for profit-driven detention of immigrants in civil immigration proceedings. It mandates that all such facilities be under civilian control and operated or regulated by the state, unless federally managed. The bill requires that any contracts for immigration detention comply with the 2011 Operations Manual ICE Performance-Based National Detention Standards and include the state as a party, necessitating approval from the attorney general. Additionally, it safeguards detainee rights by prohibiting the deprivation of access to legal counsel and protection against discrimination based on gender identity or sexual orientation.

Moreover, the bill introduces a provision that restricts the governor from deploying the National Guard to immigration detention facilities without prior consent from the executive council, ensuring oversight in the use of state resources for immigration enforcement. The bill is set to take effect on January 1, 2026, and while it does not allocate funding or authorize new positions, it acknowledges the potential for increased civil cases resulting from these changes, with average costs for civil cases estimated at $1,430 in FY 2025 and $1,473 in FY 2026. The Department of Corrections has indicated that there will be no fiscal impact on their operations, as they do not detain immigrants or receive funds for immigrant detention.
