State Governors Sign Bills on Immigration Detention and Environmental Policy

Two distinct state-level legislative developments were reported. In Maine, Gov. Janet Mills signed a law granting local jails greater flexibility in accepting immigration detainees, one of several immigration-related measures advanced by the state legislature during its session. Separately, in Montana, Gov. Greg Gianforte signed five new laws amending the Montana Environmental Policy Act, enacted in response to the state Supreme Court's Held v. Montana climate change decision. In Maine, alongside signing the detainee bill, Mills vetoed separate legislation that would have automatically sealed criminal records for many misdemeanor offenders; specific details of the immigration bill's provisions were not provided. In Montana, the five environmental laws were described by Gianforte as intended to reduce potential litigation risk and provide legal certainty for businesses following the state Supreme Court's rulings. As of the bill signing, Gianforte had signed 222 of the 878 bills passed by the Montana Legislature during the session. Both sets of laws are now enacted, with the Maine detainee measure and Montana's environmental policy changes in effect following their respective governors' signatures. The Maine veto of the record-sealing bill remains a separate, unresolved matter for future legislative action, and no timeline for reconsideration was reported. Additional specifics on the content and expected impact of the Maine immigration law, as well as details on the remaining unsigned bills in Montana, were not included in available reporting.
