The Facts
Keshawn Carter was charged with federal firearm and drug offenses. He entered a conditional guilty plea under Fed. R. Crim. P. 11(a)(2), reserving the right to appeal the denial of his motion to suppress. On appeal, Carter sought to raise a Fourth Amendment theory — the automobile exception's inapplicability — that was not raised or fully developed in the district court. The Eighth Circuit held the argument forfeited. The Supreme Court granted certiorari to resolve a circuit split on the scope of conditional plea preservation.
The Application
Carter's conditional plea preserved his right to appeal the denial of his suppression motion, which created the scope for appellate review of any Fourth Amendment theory challenging that ruling's validity. Although Carter had not specifically argued the automobile exception's inapplicability in district court, the Court held that this alternative legal theory was not forfeited because it went directly to the suppression issue he had preserved—arguing that the search fell outside the automobile exception amounts to a different avenue for attacking the same ruling, not a wholly new claim. The ruling rejects the forfeiture doctrine as an absolute bar in this context, instead tying preservation to the substance of the suppression determination rather than the particular arguments the defendant presented below. This shifts the burden away from defendants to anticipate every possible Fourth Amendment angle and allows appellate development of theories that directly implicate the preserved issue.
The Conclusion
Decided 2025. The Court clarified that conditional plea preservation is coextensive with the suppression ruling designated in the plea — defendants may raise any theory going to that ruling on appeal, not just arguments actually made below. The ruling resolves a significant circuit split on appellate preservation in federal criminal cases.
