Which description best fits concurrent jurisdiction?

Concurrent jurisdiction refers to the situation where two or more different courts have the authority to hear the same case or legal matter. This typically involves both state and federal courts having jurisdiction over certain types of violations. The correct choice captures this concept well because concurrent jurisdiction is often applied to a range of legal infractions, including both serious and minor offenses.

Minor legal infractions like misdemeanors can fall under concurrent jurisdiction, allowing either state or federal authorities to bring charges depending on the specifics of the case. This duality provides flexibility in prosecution and ensures that both levels of government are able to address violations according to their laws.

Additionally, concurrent jurisdiction is not limited to minor offenses, nor is it exclusive to federal law prosecution. The other options either narrow the scope too much, focusing mainly on either specific infractions or provoking an exclusive focus, which does not accurately represent the nature of concurrent jurisdiction.
