Arizona POST Waiver Practice Test 2026 – Complete Exam Prep

Diplomatic immunity is the key idea here. Ambassadors and foreign ministers are immune from arrest or enforcement actions by state and local authorities because they serve as heads of mission and must be able to perform their duties without fear of detention. This protection is a long-standing principle of diplomacy and is recognized in state practice to ensure smooth communications and negotiations between countries. The immunity generally covers criminal prosecutions and detention, though it can be waived by the sending country or, in some cases, end if the diplomat returns to their home country or faces a waiver.

Local government, university professors, and tourists do not have this blanket protection under the Arizona Constitution, so they can be subject to arrest or enforcement like any other resident or visitor.
