Relating to the authority of the Department of Public Safety to act during a state of invasion or imminent danger on the Texas-Mexico border.

SB 81 authorizes the Texas Department of Public Safety (DPS) to take specific actions during a declared "state of invasion or imminent danger" along the Texas-Mexico border. It directly affects individuals crossing the border illegally, migrants apprehended near the border, and suspected cartel members. Key provisions include allowing DPS to detect and repel unauthorized border crossings away from ports, return certain apprehended migrants to Mexico, inspect cargo for drugs and smuggling, and use force against known cartel operatives. The bill requires a two-thirds legislative vote for immediate effect or takes effect September 1, 2025, if not approved. This legislation expands DPS authority under Texas and U.S. constitutional provisions.
