When must an appellant file an ordinary reply brief?

Identify the appellee’s brief and establish its actual service under Rule 25, including the method and proof.

Establish the argument date and any scheduling change. Check the actual briefing order and local rules.

Distinguish ordinary Rule 31 briefing from a filed cross-appeal. Rule 28.1 displaces the ordinary Rule 31(a)(1) schedule in a cross-appeal.

1. Establish the ordinary reply stage and actual service.
2. Compute the service branch with any qualifying Rule 26(c) addition.
3. Establish and count the seven-day-before-argument filing branch backward.
4. Satisfy both applicable limits and any actual court directions.

Establish the service date under Rule 25 and compute the base service-based period under Rule 26(a), including its final-day rollover. Rule 26(c) adds three days after that base otherwise expires only when the paper was neither served electronically on the party nor delivered to that party on the proof-of-service date. Apply Rule 26(a) to the added period. This addition does not change the separate argument-based filing limit. Independently count the argument branch backward under 26(a)(5). If its final day is closed, continue backward, not forward. State-declared holidays under 26(a)(6)(C) do not apply to that backward branch.

FRAP 26(a)(1) excludes the triggering event, counts intermediate calendar days and carries a final Saturday, Sunday or legal holiday to the next qualifying day. Rule 26(a)(5) continues backward for a period measured before an event. Rule 26(a)(6) includes federal and President or Congress declared holidays. Its additional state-declared holidays apply only to forward periods, using the challenged district court’s state or the circuit clerk’s principal-office state. Check actual calendars, inaccessibility and orders.

The twenty-one-day service limb alone cannot resolve the argument backstop, conditional addition and actual court directions. No combined date or paid calculation is published.

Coupled limits

The reply must satisfy both the service period and the argument-based filing limit. One isolated twenty-one-day or seven-day output is incomplete.

Actual court permission

Later argument-proximate filing requires the court’s good-cause permission. An extension request or assumed agreement does not prove that permission.

Changed schedule

Rule 31(a)(2) permits shortening for courts that routinely consider the merits promptly. Check actual local rules and orders, not only the national default.

• The twenty-one-day service limb alone cannot resolve the argument backstop, conditional addition and actual court directions. No combined date or paid calculation is published.
• The guide does not establish disputed service, read actual orders, grant relief or verify a court’s completed acts.

• Confirm ordinary briefing and the appellant’s role.
• Preserve actual appellee-brief service and delivery evidence.
• Verify current argument scheduling and both timing limits.
• Read granted relief, filing instructions and required service.
• Court-of-appeals electronic filing ends at midnight in the circuit clerk’s principal-office time zone under FRAP 26(a)(4)(B), unless a statute, local rule or order sets a different time. Ordinary other means use scheduled clerk closing under (D). Rule 25(a)(2)(A)(ii) separately permits qualifying brief or appendix mailing or dispatch, with the chosen method’s latest delivery time under 26(a)(4)(C). Verify permitted electronic filing, any actual non-electronic exception, separate service and proof. An ordinary motion does not inherit the brief-dispatch exception.
