Summary

The Second Circuit denied Jason Robinson’s motion to dismiss the Government’s interlocutory appeal from an order suppressing cellphone evidence. The court held that later certifications by the interim United States Attorney and the Attorney General satisfied 18 U.S.C. § 3731, and that any late filing did not preclude jurisdiction or warrant discretionary dismissal.

Questions Presented

  1. Whether the Second Circuit had jurisdiction over the Government's interlocutory appeal under 18 U.S.C. § 3731 despite a challenge to the validity of the initial certification by an interim United States Attorney.
  2. Whether a later ratification by the interim United States Attorney, after appointment by the district court, could validate or serve as a belated certification under § 3731.
  3. Whether a supplemental certification by the Attorney General independently satisfied § 3731.
  4. Whether the court should exercise its discretion under Federal Rule of Appellate Procedure 3(a) to dismiss the appeal because the certification was filed late.

Holdings

  1. Timely filing of the United States Attorney's certification is not a jurisdictional requirement under 18 U.S.C. § 3731; a late certification does not preclude appellate jurisdiction, although it permits discretionary dismissal under Federal Rule of Appellate Procedure 3(a).
  2. The interim United States Attorney's later ratification of his prior actions after a valid district-court appointment, considered together with his original certification, was sufficient to satisfy § 3731 as a belated filing of the original certification.
  3. The Attorney General may certify a Government appeal under § 3731, and the Attorney General's supplemental certification independently defeated Robinson's jurisdictional challenge.
  4. The court declined to dismiss the appeal because the Government carefully analyzed the case before appealing and Robinson suffered no substantial prejudice from the late certifications.

Factual background

When Jason Robinson returned to the United States from a trip abroad in 2022, customs officials diverted him for inspection at JFK Airport. A search of his cellphone revealed evidence of child sexual abuse material, and a later warrant-authorized forensic search uncovered additional videos and photographs. The district court suppressed the cellphone evidence, finding the initial search unlawful for lack of probable cause or a warrant and rejecting the good-faith exception.

Procedural history

After Robinson returned to the United States, the district court suppressed evidence obtained from an initial cellphone search at JFK Airport, concluding that the search lacked probable cause or a warrant and that the good-faith exception did not apply. The Government timely filed a notice of interlocutory appeal and an initial certification under § 3731. The Government later submitted a ratification by the interim United States Attorney and a supplemental certification by the Attorney General. The Second Circuit denied Robinson's motion to dismiss and retained jurisdiction to decide the merits.
