Hain Celestial Group, Inc. v. Palmquist

The Supreme Court affirmed the Fifth Circuit's decision to vacate a federal judgment and remand a product liability case to state court because the District Court lacked diversity jurisdiction at the time of removal. The Court held that a district court's erroneous dismissal of a non-diverse defendant does not cure a pre-existing jurisdictional defect, as federal courts must assess jurisdiction based on the facts existing when the case was filed.

BARRETT v. UNITED STATES

The Supreme Court held that Congress did not clearly authorize cumulative convictions under both 18 U.S.C. § 924(c)(1)(A)(i) and § 924(j) for a single act. The Court reversed the Second Circuit, ruling that a single fatal violation yields only one conviction despite the provisions satisfying the Blockburger test for separate offenses.

Bost v. Illinois State Bd. of Elections

The Supreme Court held that congressional candidates possess Article III standing to challenge state election counting rules based on a concrete interest in the integrity of the electoral process. The Court reasoned that candidates suffer a particularized reputational injury when unlawful procedures undermine public confidence in election results, regardless of whether the rules alter the election outcome.

Case v. Montana

The Supreme Court clarified that the Fourth Amendment permits warrantless home entries for emergency aid when officers have an objectively reasonable basis to believe someone needs help, rejecting a probable cause requirement. The Court affirmed a conviction for assaulting an officer after police entered a home to prevent a suspected suicide based on a 911 call and visible evidence.

Bowe v. United States

The Supreme Court held that the Antiterrorism and Effective Death Penalty Act does not bar federal prisoners from seeking certiorari review of a court of appeals' denial of authorization for a second or successive § 2255 motion. The Court further ruled that the statutory bar on 'do-over' claims in § 2244(b)(1) applies only to state prisoners, not federal prisoners.
