Trespass offenses modified to require a warrant signed by a judicial officer for immigration enforcement, and detention of persons subject to civil immigration detainers issued by the federal government prohibited.

HF 3483 modifies Minnesota's trespass law to require law enforcement to obtain a warrant signed by a judicial officer before entering property for civil immigration enforcement. It also prohibits local law enforcement from detaining individuals solely based on federal civil immigration detainers. The bill amends Minnesota Statutes § 609.605 to add a specific provision (subdivision 1, clause (6)) requiring a warrant with probable cause for immigration-related trespass entries. This directly affects local police and sheriff's departments by restricting their ability to act on federal immigration requests without judicial oversight. The law applies to all trespass offenses involving immigration enforcement activities on private property.
