A federal criminal appeal is not a second trial. It is a disciplined legal challenge to the judgment of a United States District Court, litigated before a three-judge panel of the governing United States Court of Appeals on the record created below.

Whether a defendant was convicted after a jury trial or entered a guilty plea, post-judgment relief in federal court depends on identifying reversible legal or procedural error, matching each issue to the governing standard of review, and presenting the record with precision. At Federal Criminal Appeals Group, our practice focuses on the two primary pathways available after a federal conviction or sentence: federal direct criminal appeals and federal post-conviction proceedings under 28 U.S.C. § 2255.
Core Services: Direct Federal Criminal Appeals
Under Federal Rule of Appellate Procedure 4(b), a criminal defendant generally has only 14 days from the entry of judgment to file a notice of appeal. Once appellate jurisdiction attaches under 28 U.S.C. § 1291, direct federal criminal appeals examine the complete district-court record—including indictment challenges, pretrial suppression rulings under the Fourth, Fifth, and Sixth Amendments, evidentiary rulings under the Federal Rules of Evidence, jury instructions, prosecutorial conduct, and the constitutional sufficiency of the evidence.
Even when a conviction rests on a guilty plea, direct appellate review may remain available to challenge the validity of the plea colloquy under Federal Rule of Criminal Procedure 11, preserved conditional-plea suppression issues, jurisdictional defects, or errors that fall outside the scope of an appellate waiver.
Federal Sentencing Appeals & Guideline Review
A substantial share of federal appellate litigation involves federal sentencing appeals authorized by 18 U.S.C. § 3742. Appellate courts review federal sentences in two distinct stages: first for procedural reasonableness, and second for substantive reasonableness under 18 U.S.C. § 3553(a).
As detailed in our guide to building the record for procedural sentencing error, a miscalculation of the advisory United States Sentencing Guidelines range—such as an unsupported loss calculation, drug-quantity attribution, role adjustment, firearm enhancement, career-offender designation, or Armed Career Criminal Act predicate ruling—is a significant procedural error that regularly warrants vacatur and remand for resentencing unless the government proves the error was harmless.
Preservation of Error and Governing Standards of Review
Every appellate issue is filtered through its governing standard of review. Pure questions of law, statutory interpretation, constitutional claims, and guideline interpretation are generally reviewed de novo. Factual findings are reviewed for clear error, and discretionary trial or sentencing rulings are reviewed for abuse of discretion.
When trial counsel objected contemporaneously, preserved errors are evaluated under the harmless-error standard of Federal Rule of Criminal Procedure 52(a), which places the burden on the government. When an issue was not objected to in the district court, the appellant must satisfy the four-part plain-error framework under Rule 52(b). Structuring opening and reply briefs around the exact standard of review is essential to persuasive federal appellate advocacy.
Post-Conviction Relief & 28 U.S.C. § 2255 Motions
Because direct appeals are restricted to the existing district-court record, constitutional violations that depend on facts outside the trial transcript—most notably Sixth Amendment claims of ineffective assistance of counsel—must typically be raised in a collateral proceeding through 28 U.S.C. § 2255 motions.
In a § 2255 proceeding, counsel can investigate facts beyond the trial record, submit sworn declarations, expert reports, and documentary exhibits, and seek an evidentiary hearing where trial, plea, or sentencing counsel failed to investigate defenses, misadvised the client during plea negotiations, failed to object to guideline enhancements, or disregarded instructions to file a notice of appeal. Because § 2255 motions are governed by a strict one-year limitations period under 28 U.S.C. § 2255(f), early evaluation of the record and procedural history is critical.
Circuit-Specific Appellate Advocacy Across the United States
While the Federal Rules of Appellate Procedure establish a national baseline, each regional circuit applies its own body of binding precedent, local rules, briefing requirements, and oral-argument practices. Our Federal Appeals by Circuit hub provides jurisdiction-specific guidance across all twelve regional circuits, including the Ninth Circuit, Second Circuit, Fifth Circuit, and Eleventh Circuit.
