Remaining in a Restricted Area Outside Authorized Hours

A subject knowingly remains within a restricted physical area after their authorized access period has ended, or enters the area during a time when their role, assignment, escort approval, or access authorization does not permit their presence.

 

The subject may have legitimate daytime or task-based access to the location, but that authority does not extend to the time at which the presence occurs. Relevant behaviors include remaining after a shift or escorted visit, entering during a closed period, concealing continued presence after other personnel depart, or returning outside an approved access window.

 

The infringement is distinguished from accidental overstay by evidence that the subject understood the temporal restriction and deliberately remained or entered regardless.
