Magistrate Judges in this district are assigned criminal matters on a rotating weekly basis. The court is generally not available for civil hearings during its criminal duty week. Criminal call begins at 1:00 p.m. daily in the duty courtroom (Room 114) on the first floor of the Theodore Levin U.S. Courthouse in Detroit. Agents with requests for complaints, arrest warrants and other matters which require a face-to-face meeting with Judge Patti should report to the duty courtroom in person and then to chambers for review of the papers. Requests for search warrants, pen registers, orders to seal or delay notice, or non-disclosure orders are generally submitted through the U.S. Attorney’s Office by electronic means. During the week of criminal duty, questions regarding duty matters should be directed to the duty telephone at (313) 234-5558.
