This bill aims to prohibit and penalize warrantless surveillance in Montana by establishing the offense of "surveillance stalking." It defines surveillance as monitoring or recording a person's statements, movements, or activities in real time without a warrant or reasonable suspicion of criminal activity. The bill stipulates that law enforcement agencies and officers are not allowed to surveil individuals without proper legal justification. Violating this provision would result in the charge of surveillance stalking, which carries a penalty of up to one year in prison, a fine of up to $1,000, or both.

Additionally, the bill includes a severability clause, ensuring that if any part of the act is found to be invalid, the remaining valid sections will still be enforceable. This clause protects the overall integrity of the legislation by allowing it to remain effective even if certain provisions are challenged or deemed unconstitutional.
