**Diplomatic immunity** grants foreign diplomats exemption from local laws and prosecution in the host country, essential for maintaining international relations. This legal protection ensures diplomats can perform their duties without fear of harassment or interference. While they are subject to their home country's laws, immunities cover a range of activities, from **criminal prosecution** to civil suits. However, immunity does not imply blanket protection; serious offenses may lead to **expulsion** or diplomatic negotiations for resolution. Its importance lies in facilitating open dialogue and fostering peaceful international cooperation.
