5th Cir. R. 31.4 — Briefs - Time for Filing: the court's own rule, verbatim from RULES and INTERNAL OPERATING PROCEDURES OF THE UNITED STATES COURT OF APPEALS FOR THE FIFTH CIRCUIT (December 2025), official PDF, sha-custodied. Court-level requirement: applies to appeals in the U.S. Court of Appeals for the Fifth Circuit alongside the Federal Rules of Appellate Procedure.
31.4.1 General Provisions. The court expects briefs to be filed timely and without extensions in the vast majority of cases. No extensions are automatic, even where the request is unopposed. Any requests for extensions should be made sparingly. No extension can be granted without good cause shown as required by FED. R. APP. P. 26(b), or without meeting the additional requirements contained in the 5TH CIR. R. (a) A request for extension should be made as soon as it is reasonably possible to foresee the need for the extension. The clerk must receive a request for extension at least 7 days before the due date, unless the movant demonstrates, in detail, that the facts that form the basis of the motion either did not exist earlier or were not and with due diligence could not have been known earlier. (b) As specified in 5TH CIR. R. 27.1, the movant must indicate that all other parties have been contacted and whether the motion is opposed. Movants should request only as much time as is absolutely needed. The pendency of a motion for extension does not toll the time for compliance. 31.4.2 Grounds for Extensions. As justification for extensions, generalities, such as that the purpose of the motion is not for delay or that counsel is too busy, are not sufficient. Grounds that may merit consideration for extensions are, without limitation, the following, which must be set forth if claimed as a reason in any motion for an extension beyond 30 days: (a) Engagement of counsel in other litigation, provided such litigation is identified by caption, number, and court, and there is set forth: (1) A description of any effort taken to defer the other litigation and of any ruling thereon; (2) An explanation of why other litigation should receive priority over the case at hand; and (3) Other relevant circumstances, including why other associated counsel cannot prepare the brief or relieve the movant's counsel of the other litigation. (b) The matter is so complex that an adequate brief cannot reasonably be prepared when due. (c) Extreme hardship will result unless an extension is granted, in which event the nature of the hardship must be set forth in detail. 31.4.3 Levels of Extensions. There are two levels of extensions: a Level 1 extension of 1-30 days from the original due date; and a Level 2 extension of more than 30 days from the original due date. 31.4.3.1 Level 1 Extensions. The clerk is authorized to act on or refer to the court Level 1 extensions. The court prefers that an unopposed request be made by telephone, but it may be by written motion or letter. When making the request, the movant must explain what good cause exists for the extension. If the extension is granted by telephone, the movant will immediately send a confirming letter to the clerk, with copies to all parties. An opposed request for a Level 1 extension must be made by written motion setting forth why there is good cause. The motion must state the initial due date, whether any other extension has been granted, the length of the requested extension, and which parties have expressed opposition. 31.4.3.2 Level 2 Extensions. The clerk is authorized to act on or refer to the court Level 2 extensions. The request must be made by written motion, with copies to all parties, stating the initial due date, whether any other extension has been granted, the length of the requested extension, and whether the motion is opposed. More than ordinary good cause is required for a Level 2 extension, and Level 2 extensions will be granted only under the most extraordinary of circumstances. The movant must demonstrate diligence and substantial need and must show in detail what special circumstances exist that make a Level 1 extension insufficient. 31.4.4 Extensions for Reply Briefs. The court greatly disfavors all extensions of time for filing reply briefs. The court assumes that the parties have had ample opportunity to present their arguments in their initial briefs and that extensions for reply briefs only delay submission of the case to the court.
