Which group of people has the highest degree of immunity?

Diplomatic agents possess the highest degree of immunity due to the principles outlined in international law, specifically the Vienna Convention on Diplomatic Relations. This treaty establishes the framework for diplomatic relations between independent countries and outlines the privileges and immunities granted to diplomatic personnel. These immunities are essential for ensuring that diplomats can perform their duties without fear of coercion or harassment by the host country.

Diplomatic agents enjoy extensive protections, including immunity from arrest and detention, exemption from taxation for their official activities, and protection from legal processes related to their official functions. This level of immunity is crucial for maintaining international relations and enabling effective diplomacy.

In contrast, while military personnel, judicial officials, and international observers do have certain protections and privileges, they do not generally enjoy the same breadth of immunity that diplomatic agents do. For example, military personnel may be subject to the laws of the host country under certain conditions, judicial officials have specific judicial immunity that can vary widely, and international observers operate under agreements that grant them limited immunity related to their specific missions.
