How many categories of federal territorial jurisdiction exist?

Federal territorial jurisdiction is categorized into three distinct types: exclusive jurisdiction, concurrent jurisdiction, and proprietary jurisdiction. Exclusive jurisdiction occurs when the federal government has sole authority over a territory, such as federal land, military bases, and the District of Columbia, meaning no state laws apply. Concurrent jurisdiction allows both state and federal governments to exercise authority, often seen in areas where federal laws and state laws coexist. Lastly, proprietary jurisdiction refers to instances where the federal government has control over a specific area and can legislate and enforce laws, but the state retains the right to govern in other aspects. Understanding these three categories is vital for law enforcement, legal professionals, and anyone involved in federal jurisdiction matters, as they define the scope and limits of legal authority across different territories.
