AO 102: Application for a Tracking Warrant
AO 102, Application for a Tracking Warrant, is a form from the U.S. Courts in which a federal law enforcement officer or attorney for the government asks a United States District Court, in furtherance of a criminal investigation, for authority to install and use a tracking device or use the tracking capabilities of the property or object described to determine location. The U.S. Courts list it under Law Enforcement, Grand Jury, and Prosecution Forms. The PDF prints the edition (01/09), and the U.S. Courts page lists it as effective on January 1, 2009.
The one-page application names the U.S. Code violations involved, where the person, property or object is located, the bases for the warrant under Fed. R. Crim. P. 41(c), any request to enter a vehicle or private property, and any request for delayed notice under 18 U.S.C. § 3103a. The facts go on an attached sheet. The applicant signs it, and it is sworn to before a judge, who signs it. The form is written for federal officers and government attorneys, not for members of the public.
