THE SECOND CIRCUIT'S APPENDIX OPTIONS – STRATEGY IS KEY
- Jul 2
- 3 min read

The appendix plays a critical role in federal appellate practice. Rather than requiring the Court to sift through the entire district court record, the appendix contains the portions of the record relevant to the issues on appeal and serves as the primary source for record citations in the parties' briefs. The full record remains available to the Court, but the appendix is intended to contain only those materials necessary for appellate review.
In Second Circuit appeals, the traditional approach is to prepare a joint appendix. FRAP 30 (c) also permits the use of a deferred appendix. Understanding the differences between these procedures early in the appeal can have a meaningful impact on both litigation costs and the briefing schedule.
The Joint Appendix Process Begins with Designations
FRAP 30 places the initial responsibility for preparing and paying for the joint appendix on the appellant, making disputes over appendix contents particularly significant in record-heavy appeals.
Where the parties cannot agree on the contents of the joint appendix, FRAP 30(b)(1) requires an exchange of record designations. The appellant must serve its designation and statement of issues within 14 days after the record is transferred from the court of original instance. The appellee then has 14 days to designate additional portions of the record.
The appellant is required to include those additional designations in the joint appendix, even if it disagrees with their necessity. While the rules permit cost-shifting for materials the appellant believes are unnecessary, those designations must still be included.
In appeals involving substantial evidentiary records, lengthy transcripts, or extensive motion practice, those additional designations can significantly increase the size—and cost—of the joint appendix.
When the Parties Cannot Agree
In appeals involving larger records, agreement on what should ultimately be included in the appendix can prove difficult.
By the time the designation process is completed, the parties may have identified hundreds—or thousands—of pages for inclusion. Yet many of those documents may never be cited in the briefs. When that occurs, counsel should consider whether a deferred appendix may provide a more efficient path forward.
How the Deferred Appendix Changes the Briefing Schedule
Under the traditional process, a joint appendix is filed with the appellant's opening brief.
However, in some appeals, either by court order or by stipulation of the parties, a deferred appendix may be filed. Instead of preparing the appendix before briefing begins, the parties initially file page-proof briefs containing citations directly to the district court record as outlined in FRAP 30(c)(2).
Once briefing is complete, the deferred appendix is assembled using the portions of the record cited in the briefs. The parties then submit final-form briefs replacing district court record citations with deferred appendix citations. Other than correcting typographical errors and updating the citations, the parties may not make any changes to the briefs.
Because the procedure requires the filing of both page-proof and final-form briefs, any potential savings from a deferred appendix should be weighed against the additional production work and costs associated with those filings. In practice, a deferred appendix is often most effective when a significant reduction in appendix size is expected.
For many appeals, the benefit is straightforward: rather than debating appendix contents before the briefs are drafted, counsel can identify the materials actually necessary to their arguments and provide the Court with a streamlined appendix containing only those documents cited in the briefs. In record-heavy appeals, that approach can reduce costs and avoid disputes regarding documents that ultimately play no role in the appeal.
A Strategic Decision Early in the Appeal
Whether to proceed with a joint appendix or a deferred appendix should be considered at the outset of every Second Circuit appeal. Most importantly, appellants should understand the designation deadlines under FRAP 30 and how those deadlines interact with the briefing schedule. If agreement on the contents of the appendix proves difficult, the deferred appendix process requires either a stipulation between the parties or a court order. Where motion practice becomes necessary, counsel should account for the additional time required to obtain that relief while ensuring compliance with all applicable briefing and filing deadlines.
