United States · Federal appellate briefing

When must the cross-appeal appellee serve and file its principal and response brief?

FRAP 28.1(f)(2) requires the appellee’s principal and response brief to be served and filed within thirty days after service of the appellant’s principal brief. Rule 28.1(c)(2) combines the cross-appeal principal case and appeal response in one brief. Rule 26(c) may add three days. The isolated preset does not calculate that addition.

Which filing or service starts this briefing stage?

Verify the actual Rule 28.1 appellee role.

Identify service of the appellant’s principal brief.

Establish service method and actual delivery facts.

Prepare the one combined principal and response brief and read actual directions.

FRAP 28.1(f)(2)

Why is no combined deadline calculated?

  1. Identify the actual procedure and required actor.
  2. Read the controlling event, service or stay evidence.
  3. Apply applicable additions, coupled limits and actual directions.
  4. Complete the required acts and preserve proof.

First compute the base period under FRAP 26(a), excluding the service day and counting every calendar day, with final-day rollover. When the paper was neither served electronically nor delivered on the date stated in the proof of service, Rule 26(c) adds three days after that base otherwise expires. Apply final-day rollover to the added period. The isolated preset does not calculate that addition.

Rule 26(a)(6) includes the listed federal holidays and days declared holidays by the President or Congress. For periods after an event, it also includes holidays declared by the state of the district court that rendered the challenged judgment or order, or the circuit clerk’s principal office. Establish the actual applicable calendar and inaccessibility. The national preset does not infer additional state holidays or granted relief.

FRAP 26(a)(4)–(6), (b) and (c)

Why is no automated date shown?

The isolated thirty-day cross-appeal appellee preset omits the possible Rule 26(c) addition. No computed date or paid calculation record is published.

Which qualifications affect the briefing stage?

Combined brief
Rule 28.1(c)(2) requires the appellee’s principal brief in the cross-appeal and response to the principal appeal in the same brief.
Actual role
Rule 28.1(b) role designations can be modified by agreement or court order. Establish the actual appellee before identifying this stage.
Service-based period
The thirty days start after service of the appellant’s principal brief. Rule 26(c) may add days based on actual service and delivery conditions.
Both acts
Rule 28.1(f) requires the combined brief to be served and filed, not merely prepared.
FRAP 28.1(f)(2)
  • This guide does not read local rules or orders, infer service or delivery, determine an appeal’s merits or grant relief.
  • Confirm actual briefing roles, separate service and current circuit requirements before using a national default.

What should I check before completing this act?

Common questions

Briefing roles, events and service

Are the principal cross-appeal and response separate briefs?

Rule 28.1(c)(2) requires them in the same brief.

FRAP 28.1(a)–(c)

Does record filing start this appellee stage?

Rule 28.1(f)(2) uses service of the appellant’s principal brief. Record filing starts a distinct principal-brief stage.

FRAP 28.1(f)

Does the thirty-day preset include added service time?

No. Rule 26(c) requires actual service and delivery facts, which this preset does not collect.
