What does proprietary jurisdiction refer to?

Proprietary jurisdiction refers to the military exercising rights similar to those of a property owner. This concept arises in the context of military installations and properties where the military has certain authorities and responsibilities akin to those of a private landowner. Under proprietary jurisdiction, the military is not acting in the capacity of government authority but rather as an owner of the land, giving them the ability to control activities on that property with a focus on security, management, and regulation of that space. This form of jurisdiction does not extend to law enforcement powers over civilians outside the property, distinguishing it from other types of jurisdiction.

The other choices do not correctly capture the essence of proprietary jurisdiction. The military maintaining authority over criminal behavior focuses on the enforcement aspect, which is more aligned with exclusive jurisdiction. The exclusive rights of a city to regulate property pertain to municipal jurisdiction, and joint ownership of law enforcement rights suggests a collaborative governance model that does not accurately reflect the situation under proprietary jurisdiction.
