Diplomatic immunity is a legal principle that protects diplomats from being prosecuted or sued under the host country's laws. This immunity allows diplomats to perform their duties without fear of harassment or interference. It is based on international agreements, primarily the Vienna Convention on Diplomatic Relations of 1961, which outlines the rights and responsibilities of diplomats. While diplomatic immunity provides significant protections, it is not absolute. Diplomats can still be expelled from the host country for serious offenses. Additionally, their home country may choose to waive immunity in cases of severe misconduct, ensuring accountability while maintaining diplomatic relations.
