NJ Court: Warrants Needed For Cellphone Tracking

TRENTON, N.J. (AP) -

Police in New Jersey will soon have to get a warrant if they want to track a suspect using cellphone locating data, the state Supreme Court ruled unanimously Thursday, invalidating the arrest of a burglary suspect in 2006 because police located him using data from T-Mobile without getting a warrant.

The rule won’t be applied to cases retroactively, with the exception of the case in question.
