Adeia, ‘immunity’, sometimes in Greece offered to men accused of involvement in a crime who were willing to inform on others (e.g. Andocides in Athens' religious scandals of 415 bce). In Athens the term is used also of a special vote by the assembly permitting itself to discuss a subject which otherwise it would be forbidden to discuss (e.g. to levy the tax called eisphora) or more generally to override an ‘entrenchment clause’ in an earlier decree forbidding discussion of a matter without a vote of immunity. Such clauses were intended to prevent over-hasty decisions by requiring two votes at separate meetings of the assembly before action could be taken on an entrenched matter.
