Diplomatic immunity is based on what assumption?

diplomatic immunity  is a form of  legal immunity  that makes sure  diplomats  are given safe passage and are considered not susceptible to  lawsuit  or  prosecution  under the host country's laws, although they can still be  expelled. modern diplomatic immunity was codified as  international law  in the  vienna convention on diplomatic relations  (1961) which has been ratified by all but a handful of nations, though the concept and custom of such immunity have a much longer history dating back thousands of years. many principles of diplomatic immunity are now considered to be  customary law. diplomatic immunity as an institution developed to allow for the maintenance of government relations, including during periods of difficulties and  armed conflict. when receiving diplomats, who formally represent the sovereign, the receiving head of state grants certain privileges and immunities to ensure they may effectively carry out their duties, on the understanding that these are provided on a reciprocal basis.

originally, these privileges and immunities were granted on a  bilateral,  ad hoc  basis, which led to misunderstandings and conflict, pressure on weaker states, and an inability for other states to judge which party was at fault. an international agreement known as the vienna conventions codified the rules and agreements, providing standards and privileges to all states.

it is possible for the official's home country to waive immunity; this tends to happen only when the individual has committed a serious  crime, unconnected with their diplomatic role (as opposed to, say, allegations of  spying), or has witnessed such a crime. however, many countries refuse to waive immunity as a matter of course; individuals have no authority to waive their own immunity (except perhaps in cases of  defection). alternatively, the home country may prosecute the individual. if immunity is waived by a government so that a diplomat (or their family members) can be prosecuted, it must be because there is a case to answer and it is in the public interest to prosecute them. for instance, in 2002, a colombian diplomat in london was prosecuted for manslaughter, once diplomatic immunity was waived by the colombian government.
