Which jurisdiction must courts have in order to hear a particular case?

For a court to have the authority to hear and decide a case, it must have two distinct types of jurisdiction. First, it needs personal jurisdiction (jurisdiction in personam), which is the power over the specific parties (individuals or entities) in the case. Second, it requires subject matter jurisdiction (jurisdiction in rem), which is the power to hear the particular type of legal dispute being presented. Without both, the court cannot issue a valid, binding judgment. This fundamental principle ensures that legal proceedings are conducted in a proper and constitutionally sound forum.

A: "Regulatory jurisdiction" is the authority of an administrative agency, such as the FTC or FCC, not a court. B: "Professional jurisdiction" is not a standard legal term for a court's authority to preside over a legal case. D: "Professional jurisdiction" is not a recognized type of court jurisdiction required to hear a legal case.
