A basis for a court's authority to adjudicate a dispute arising from the nature of the subject matter presented.
Roberto Reyes filed a federal suit against Redline Automotive alleging breach of a supply contract. The district court determined it lacked subject-matter jurisdiction over the state-law claim. The court dismissed the action under the governing rule.
Rhea Reynolds sued Riverside Healthcare in federal court for damages arising from a medical procedure. Riverside filed a motion asserting lack of subject-matter jurisdiction. The court considered the motion as a threshold defense before addressing the merits.
Robert Rivera, an insured party, sued Raven Logistics after a coverage denial in an international shipping loss. The court examined whether the claims fell within its authority based on the subject matter of the dispute. The analysis turned on the nature of the underlying conduct and applicable law.
In the late 1970s, ISO, an association of approximately 1,400 domestic property and casualty insurers that serves as the almost exclusive source of support services for CGL insurance in the United States, began revising its 1973 standard CGL policy form. The 1973 form provided occurrence-based coverage for sudden and accidental pollution and did not cap defense costs. Primary insurers including Hartford Fire Insurance Company, Allstate Insurance Company, Aetna Casualty and Surety Company, and CIGNA Corporation sought four changes: a shift to claims-made coverage with a retroactive date, elimination of pollution coverage, and a legal defense cost cap. After ISO proposed 1984 forms that omitted some of these changes, Hartford persuaded General Reinsurance Corporation, the largest American reinsurer, to procure the modifications or derail the program. The Reinsurance Association of America agreed to boycott the 1984 forms unless the changes were added, and domestic and London reinsurers informed ISO they would withhold reinsurance until the forms were altered. ISO then withdrew the 1984 forms and adopted 1986 forms containing a retroactive date and pollution exclusion; it later withdrew support services for the 1973 form. Separate agreements among London reinsurers required primary insurers to switch to claims-made policies and excluded pollution coverage from reinsurance contracts covering North American risks. Nineteen states and many private plaintiffs filed 36 complaints alleging that these actions violated section 1 of the Sherman Act. The cases were consolidated in the Northern District of California. The District Court granted motions to dismiss in 1989, holding the conduct fell within McCarran-Ferguson immunity and applying international comity to the foreign defendants. The Ninth Circuit reversed in 1991. The Supreme Court granted certiorari in 1992.
View caseRaymond Ramos, a local official, challenged a federal directive requiring state enforcement actions. The court assessed whether the subject matter implicated core sovereign functions. The decision hinged on the limits of federal power over the disputed regulatory scheme.
In 1993 Congress amended the Gun Control Act of 1968 by enacting the Brady Handgun Violence Prevention Act, which directed the Attorney General to create a national instant background-check system by November 30, 1998, and imposed interim requirements on firearms dealers and chief law enforcement officers until that system became operational. Under the interim scheme a dealer proposing to transfer a handgun had to obtain a sworn Brady Form from the purchaser, verify the purchaser's identity, forward notice and a copy of the form to the CLEO of the purchaser's residence, and wait five business days before completing the sale unless the CLEO notified the dealer that the transfer would not violate the law. Jay Printz, CLEO for Ravalli County, Montana, and Richard Mack, CLEO for Graham County, Arizona, filed separate federal actions challenging the constitutionality of the interim provisions that required CLEOs to perform background checks and related tasks. In each case the district court held that the obligation imposed on CLEOs was unconstitutional but severable from the remainder of the Act, leaving in place a voluntary background-check system. The Ninth Circuit consolidated the appeals and reversed, holding that none of the Brady Act's interim provisions violated the Constitution. The Supreme Court granted certiorari.
View caseRebecca Ross, a detainee, petitioned for review of proceedings before a military commission. The court evaluated whether the charges fell within the tribunal's subject-matter authority. The ruling addressed the scope of offenses cognizable in that forum.
Salim Ahmed Hamdan, a Yemeni national, was captured by militia forces in Afghanistan in November 2001 during hostilities between the United States and the Taliban regime that then governed the country. The militia turned him over to the United States military, which transported him to the detention facility at Guantanamo Bay, Cuba, in June 2002. Over a year later, on July 3, 2003, the President determined that Hamdan was eligible for trial by military commission for then-unspecified crimes. Subsequently, on July 13, 2004, the government charged Hamdan with one count of conspiracy to commit offenses triable by military commission. The charging document alleged that from February 1996 to November 2001 he had joined an enterprise with al Qaeda members and committed four overt acts in furtherance of that conspiracy. Hamdan then filed petitions for writs of habeas corpus and mandamus in the United States District Court for the District of Columbia to challenge both the authority of the military commission and the procedures it would employ. The District Court granted Hamdan's habeas petition on November 8, 2004, stayed the commission proceedings, and concluded that the commission lacked authority under the law of war and violated both the Uniform Code of Military Justice and Common Article 3 of the Geneva Conventions. The Court of Appeals for the District of Columbia Circuit reversed that decision, holding that the Geneva Conventions were not judicially enforceable and that the commission's jurisdiction and procedures were lawful. The Supreme Court granted certiorari on November 7, 2005. On December 30, 2005, Congress enacted the Detainee Treatment Act, after which the government moved to dismiss the case for lack of jurisdiction. The Supreme Court postponed ruling on the motion and later denied it, retaining jurisdiction over the appeal.
View caseRatione materiae concerns jurisdiction based on the subject matter of the dispute. Ratione personae concerns jurisdiction based on the identity or status of the person involved.
The ICC's jurisdiction ratione materiae extends only to genocide, crimes against humanity, war crimes, and the crime of aggression. These are the four core crimes enumerated in the Rome Statute.
No. Article 27 of the Rome Statute provides that official capacity or immunities under national or international law shall not bar the Court from exercising jurisdiction over a person.
A federal court must dismiss the action at any time if it determines that subject-matter jurisdiction is lacking. This obligation applies even if the parties have not raised the issue.
