The local rules of each district court typically will provide a timetable for briefing and opposing motions filed in that district. For example, the Northern District of Texas requires a movant to accompany any motion to quash with a brief in support and a proposed order. N.D. Tex. L.R. 7.1(d), (h). Non-movants must file response briefs to an opposed motion within 20 days of the date on which the motion and brief were filed. Id. 7.1(e). Unless otherwise directed by the presiding judge, the movant's reply brief must be filed within 15 days of the filing of the response brief. Id. 7.1(f). Of course, a presiding judge may be willing to impose a modified briefing schedule if necessitated by the circumstances.
