Relating to requiring a search warrant to obtain or use certain purchase information in a criminal action.

HB 4357 requires law enforcement to obtain a search warrant before accessing or using financial records (like bank or credit/debit card transactions) related to firearm or ammunition purchases in criminal investigations. It applies specifically to records showing purchases of firearms or ammunition, directly affecting police and prosecutors seeking such data. The bill mandates warrants must be issued by a judge in the same judicial district as the law enforcement agency, with written applications detailing probable cause and specific record details. Records gathered without a warrant under this law cannot be used in criminal court, effective September 1, 2025.
