Reverse Search Warrants

NACDL is working with coalition partners in New York to ban reverse search warrants. 

Reverse search warrants, or geofence warrants, require companies like Google to produce data regarding all devices using the company's services within a certain geographic area during a given period of time.

NACDL's Fourth Amendment Center worked with organizational partners and legislators to draft legislation in 2020 (Senate Bill 8183) to prohibit geofence warrants and voluntary reverse location requests, through which law enforcement can attain location data from data brokers and other companies without a warrant.
