Which of the following scenarios illustrates proprietary jurisdiction?

Proprietary jurisdiction refers to the authority exercised by the military over property it owns, where it has the right to manage and enforce regulations specific to that property, much like a private entity would. In this scenario, a military base managing its own property and enforcing laws on that property exemplifies this concept clearly. The military has the ability to regulate activities and maintain order within its own space without interference from local or state authorities, reflecting the independence and control associated with proprietary jurisdiction.

The other scenarios do not illustrate proprietary jurisdiction as clearly. The enforcement of state traffic laws by the military is more indicative of concurrent jurisdiction, where both military and civilian authorities have overlapping responsibilities. Joint management of laws involves collaboration rather than sole authority, which does not align with the definition of proprietary jurisdiction. Lastly, a local agency taking precedence over military authority suggests a limitation on military control, contradicting the essence of proprietary jurisdiction, where the military retains authority over its own land and operations.
