State of Minnesota v. Ivan Contreras-Sanchez

Summary

The court held under Article I, Section 10, of the Minnesota Constitution that users have a reasonable expectation of privacy in location data stored by Google, making law enforcement's access to that data a search requiring a warrant. It rejected the categorical claim that geofence warrants are general warrants and concluded that the warrant application established probable cause, but held that the warrant was insufficiently particular because it gave officers unchecked discretion to obtain expanded location data without judicial review. The court reversed and remanded for the court of appeals to consider the good-faith exception and harmless-error issues.
