Case Explained: United States of America v. Theotis Thornton

Court: United States Court of Appeals for the Eighth Circuit

Filed: 2026-07-07

The eighth-circuit affirmed the defendant’s conviction despite noting that his notice of appeal was filed one day late, classifying the filing deadline as a non-jurisdictional claims-processing rule rather than a bar to jurisdiction. The court held that because Thornton entered an unconditional guilty plea to charges under 21 U.S.C. § 841(a)(1), (b)(1)(a), 18 U.S.C. § 922(g)(1), and 18 U.S.C. § 924(c)(1)(A), he waived all nonjurisdictional defenses, including the suppression of evidence seized during a house search, unless such issues were expressly reserved by a conditional plea. As the record showed no indication that Thornton could reasonably expect to appeal the denial of his motion to suppress and no reservation was made, the court ruled he lacked standing to challenge the district court’s ruling on those grounds. The practical consequence is that the conviction stands and the appeal is dismissed on the merits due to the waiver resulting from the unconditional plea.
