Maine Revised Statutes Title 16. Court Procedure--Evidence § 648. Search warrant needed for acquisition of location information

Except as provided in this subchapter, a government entity may not obtain location information without a valid warrant issued by a duly authorized justice, judge or justice of the peace using procedures established pursuant to Title 15, section 55 or 56.

A justice, judge or justice of the peace may issue a search warrant for the location information of an electronic device pursuant to this section for a period of time necessary to achieve the objective of the authorization, but in any case the warrant is not valid for more than 14 days after the issuance. A justice, judge or justice of the peace may grant an extension of a warrant upon a finding of continuing probable cause and a finding that the extension is necessary to achieve the objective of the authorization. An extension may not exceed 30 days.

This subchapter does not apply to tracking devices, as defined in section 638, placed by law enforcement officers.
