Davis-Conforming Superseding Indictments Are Timely When They Do Not Materially Broaden the Charged Conduct

1. Introduction

In United States v. Padilla-Galarza (1st Cir. May 6, 2026), the First Circuit affirmed Jose Padilla-Galarza’s post-bench-trial convictions arising from a 2010 armed robbery of a Puerto Rico police compound shooting range, during which two officers were taken hostage and 125 firearms were stolen. The case’s appellate center of gravity was procedural: whether a superseding indictment, filed after the limitations period, could “fix” a now-invalid 18 U.S.C. § 924(c) predicate in light of United States v. Davis, and whether late-stage trial-management rulings (continuances and defense funding) unfairly impaired the defense.

Key issues included:

  • Statute of limitations: Were the superseding § 924(c) count (Count Two) and the newly added substantive Hobbs Act robbery count (Count Six) time-barred?
  • Trial management/discretion: Did denial of last-minute continuances and investigatory/expert funding requests constitute reversible abuse of discretion?
  • Evidence/credibility: Could appellate review overturn guilty verdicts premised on allegedly inconsistent cooperating-witness testimony without specific fact findings under Rule 23(c)?
  • Discovery/evidentiary rulings: Were limits on impeachment methods and denial of access to polygraph results reversible error?

2. Summary of the Opinion

The First Circuit affirmed. It held that the superseding indictment was timely because it did not “materially broaden” or “substantially amend” the charges relative to the original timely indictment, and it provided fair notice of the conduct at issue. It also found no abuse of discretion (and no prejudice) in the district court’s denial of continuances and defense funding requests, rejected credibility-based attacks as improper invitations to reweigh evidence, and found no reversible error in the contested impeachment and polygraph-related rulings.

3. Analysis

A. Precedents Cited

1) Timeliness of superseding indictments: notice and “no material broadening”

  • United States v. O'Bryant, 998 F.2d 21 (1st Cir. 1993): The court applied O’Bryant’s rule that a superseding indictment filed after the limitations period remains timely so long as it “neither materially broadens nor substantially amends” the charges, with the core inquiry being whether the original indictment gave “fair notice” of the conduct for which the defendant must prepare a defense. Here, the First Circuit treated O’Bryant as controlling and found the superseding counts tracked the same robbery conduct already alleged.

2) The legal trigger for the superseding indictment: invalidating a § 924(c) predicate

  • United States v. Davis, 588 U.S. 445 (2019): Davis held Hobbs Act conspiracy can no longer serve as a predicate “crime of violence” for § 924(c). The superseding indictment in Padilla-Galarza was a direct response: it changed Count Two’s predicate from Hobbs Act conspiracy to substantive Hobbs Act robbery and added Count Six charging the robbery (aiding and abetting).

3) Prosecutorial discretion and vindictiveness concerns

  • United States v. Chagra, 669 F.2d 241 (5th Cir. 1982): Cited to support that the government may supersede pretrial for legitimate, non-vindictive reasons (including correcting legal defects), and that superseding is improper if used to harass/punish.
  • United States v. Bucci, 582 F.3d 108 (1st Cir. 2009): Cited for the difficulty of establishing vindictive prosecution pretrial given prosecutorial discretion and a presumption of good faith. The court used Bucci to reinforce that conforming charges to post-Davis law was legitimate.

4) Continuances: “unreasoning and arbitrary insistence upon expeditiousness” plus prejudice

  • United States v. Delgado-Marrero, 744 F.3d 167 (1st Cir. 2014): Standard of review (abuse of discretion) and prejudice requirement.
  • United States v. Saccoccia, 58 F.3d 754 (1st Cir. 1995): Trial-management leeway; abuse exists only with arbitrary insistence on speed.
  • Morris v. Slappy, 461 U.S. 1 (1983): Source of the “unreasoning and arbitrary insistence upon expeditiousness” formulation.
  • United States v. Williams, 630 F.3d 44 (1st Cir. 2010): Factors for continuance analysis (reasons, diligence, inconvenience, utility).
  • United States v. Carbone, 110 F.4th 361 (1st Cir. 2024): Defendant must show “specific, concrete” ways denial caused “substantial prejudice.”

5) Funding for defense services under § 3006A(e)

  • United States v. Correa-Alicea, 585 F.3d 484 (1st Cir. 2009): Abuse-of-discretion review for denying § 3006A(e) requests.
  • United States v. Manning, 79 F.3d 212 (1st Cir. 1996): Funding generally appropriate when services are “pivotal” to the defense.
  • United States v. Mateos-Sanchez, 864 F.2d 232 (1st Cir. 1988): Applicant must show necessity with specificity; general usefulness is insufficient.
  • United States v. Prieto, 812 F.3d 6 (1st Cir. 2016): “Substantial leeway” in necessity determinations; new trial requires “clear and convincing” prejudice.
  • United States v. Scott, 48 F.3d 1389 (5th Cir. 1995): A request for time to hire an expert is not automatically a request for court funds.

6) Credibility, sufficiency, and appellate restraint

  • United States v. Rosario-Pérez, 957 F.3d 277 (1st Cir. 2020): Credibility and reliability are for the factfinder; impeachment does not itself undo sufficiency.

7) Waiver/forfeiture principles on appeal

  • United States v. Torres, 162 F.3d 6 (1st Cir. 1998): Arguments first raised in a reply brief are waived.
  • United States v. Zannino, 895 F.2d 1 (1st Cir. 1990): Undeveloped arguments are waived.

8) Rule 16 discovery violations require prejudice

  • United States v. Rosario-Peralta, 175 F.3d 48 (1st Cir. 1999): A Rule 16 violation warrants relief only upon a showing of prejudice.

B. Legal Reasoning

1) The superseding indictment “related back” because it did not broaden the conduct and, if anything, narrowed exposure

The court treated the superseding indictment as a legally necessary “Davis repair” rather than a new prosecution theory. Two aspects were decisive under United States v. O'Bryant:

  • Fair notice from the original indictment: The superseding Count Six (substantive Hobbs Act robbery) used language that mirrored the original indictment’s description of the robbery conduct (the taking of 125 firearms by force/threat at the shooting range). Because Padilla was already on notice that the government would litigate that robbery conduct, adding Count Six did not change the essential factual scenario he had to defend.
  • No material broadening / no substantial amendment:
    • Count Two was narrowed by changing “brandish and possess” to “carry and use,” reducing the mandatory minimum from seven to five years.
    • Changing the § 924(c) predicate from Hobbs Act conspiracy (Count One) to substantive Hobbs Act robbery (Count Six) did not expand the “activities alleged”; it aligned the charging instrument with Davis and arguably increased the government’s burden (proving the substantive robbery rather than merely an agreement).

The court also rejected the defense claim that Count Six’s late filing prejudiced trial strategy (i.e., a plan to move to dismiss Count Two under Davis): a defendant’s hoped-for procedural advantage is not “prejudice” of the kind that makes an otherwise proper superseding indictment untimely, particularly where the superseding served a legitimate, non-vindictive rationale under United States v. Chagra and United States v. Bucci.

2) Continuances: no arbitrariness and no concrete prejudice

Applying United States v. Saccoccia and related continuance jurisprudence, the First Circuit emphasized the extraordinary passage of time (about twelve years from robbery to trial) and the trial court’s legitimate concern about further erosion of evidence and memory. On the merits of the asserted needs:

  • Cell-site/location interpretation: The government agreed it would not use the phone records for location purposes, undercutting the claimed need for delay.
  • Jencks material and a newly cooperative witness: Although Padilla learned shortly before trial that Samuel Figueroa would testify, Padilla already knew him (they were co-defendants in a prior case), and the additional discovery sought was characterized as largely “collateral impeachment” material.

Critically, the defense did not identify “specific, concrete” prejudice as required by United States v. Carbone—only general claims that more impeachment might have been found.

3) Defense funding: specificity and necessity are required, and courts are not obliged to grant what is not requested

The court separated three issues:

  • No actual expert-funds motion (April 2022): Padilla mentioned needing time to “retain an expert” but did not file a funding request; per United States v. Scott, such language is not automatically a § 3006A(e) motion. The district court therefore could not have abused discretion by denying a request never made.
  • Investigatory funding motions (Oct./Dec. 2021): Under United States v. Mateos-Sanchez and United States v. Manning, Padilla had to show necessity with specific tasks and relevance. The motions were denied as insufficiently specific (first) and unsubstantiated (second, alleging government misconduct). The district court even invited a renewed, better-grounded request, which was not supplied.
  • No hearing required on an inadequate proffer: Under United States v. Prieto, courts have substantial leeway in managing § 3006A(e) applications; declining a hearing was not error where the written showing was facially deficient and the court had invited clarification in writing.

4) Bench trial credibility disputes: without Rule 23(c) findings, appellate review is for sufficiency, not reweighing

Because Padilla did not request specific findings under Fed. R. Crim. P. 23(c), the record contained no explicit credibility determinations. The First Circuit therefore framed the issue as sufficiency: whether evidence existed from which the trial judge could find guilt beyond a reasonable doubt. Relying on United States v. Rosario-Pérez, it rejected the invitation to overturn verdicts based on asserted witness inconsistencies—an argument that effectively asks the appellate court to retry credibility.

5) Impeachment management and polygraph discovery: waiver, discretion, and lack of prejudice

  • Prior inconsistent statements / leading questions: The court found no reversible error because (i) Padilla did introduce certain prior statements (Ayala) through an FBI agent; (ii) an argument raised only in the reply brief was waived under United States v. Torres; and (iii) the trial court acted within discretion under Fed. R. Evid. 611(c) in refusing leading questions on direct absent a showing the witness was hostile or aligned with an adverse party. The opinion also noted Padilla did not otherwise pursue admissibility under Fed. R. Evid. 613.
  • Polygraph results: The district court treated the request under Fed. R. Crim. P. 16 (materiality to preparing the defense) and denied it as immaterial because it would not admit or give weight to polygraphs. On appeal, the First Circuit found no basis for relief because, per United States v. Rosario-Peralta, even assuming error, Padilla did not show prejudice: he did not demonstrate the results were favorable, showed no investigative lead value, and any incremental impeachment would have been cumulative given other impeachment evidence and the court’s stated skepticism of polygraphs.

C. Impact

This decision’s practical precedential force lies in its application of the First Circuit’s “relation-back” doctrine for superseding indictments to the post-Davis charging environment:

  • Post-Davis charging repairs are not automatically time-barred: Prosecutors may supersede after the limitations period to replace an invalid § 924(c) predicate, including by adding a substantive offense count, so long as the original indictment already provided fair notice of the underlying conduct and the superseding does not materially broaden the case.
  • “Broadening” is measured by conduct notice, not by lost defense tactics: The court rejected the notion that thwarting a planned Davis-based dismissal strategy is the type of prejudice that transforms a conforming superseder into a limitations violation.
  • High bar for reversal on docket-control rulings: The decision reinforces that last-minute continuance requests require a concrete showing of necessity and prejudice, particularly in long-delayed prosecutions where courts may prioritize evidentiary reliability.
  • Defense funding requests must be specific and actually filed: Vague assertions of usefulness or generalized concerns about misconduct will not meet § 3006A(e)’s necessity threshold; and courts are not expected to infer requests not made.
  • Polygraph litigation remains an uphill battle: Where the factfinder announces polygraphs will carry no weight, defendants will struggle to show Rule 16 materiality or appellate prejudice.

4. Complex Concepts Simplified

  • Superseding indictment: A new indictment that replaces or modifies an earlier one. It can be filed to correct defects, add charges, or update legal theories.
  • Statute of limitations & “relation back” (O’Bryant): Even if a superseding indictment is filed after the deadline, it can still be treated as timely if it does not significantly change the core conduct alleged and the defendant had fair notice from the original indictment.
  • § 924(c) predicate “crime of violence”: A § 924(c) gun charge requires an underlying qualifying offense. After United States v. Davis, certain offenses (like Hobbs Act conspiracy) no longer qualify, forcing prosecutors to rely on other predicates.
  • Jencks Act (18 U.S.C. § 3500): Requires the government to produce certain prior statements of a testifying witness; it typically operates close to trial.
  • Brady vs. Rule 16: Brady concerns disclosure of favorable, material evidence (often constitutional). Rule 16 is a rule-based discovery regime requiring production of certain items material to preparing the defense. The standards and remedies differ.
  • Rule 23(c) findings in bench trials: In a non-jury trial, the judge need only announce guilty/not guilty unless a party timely requests specific findings. Without such findings, appellate courts generally review for overall sufficiency, not granular credibility calls.
  • § 3006A(e) defense services: Indigent defendants can seek public funds for investigators/experts, but must explain with specificity why the services are necessary (not merely helpful).

5. Conclusion

United States v. Padilla-Galarza confirms that a post-United States v. Davis superseding indictment—adding a substantive Hobbs Act robbery count and retargeting a § 924(c) predicate—remains timely under United States v. O'Bryant when it does not materially broaden the charged conduct and instead preserves fair notice. The decision also underscores the First Circuit’s demanding prejudice requirements for reversing trial-management and discovery rulings: late continuances, vague funding requests, and speculative impeachment theories—especially in a bench trial where the judge disclaims reliance on polygraphs—rarely warrant a new trial absent a concrete showing of necessity and harm.
