The Procedure phase authority table is a controlled vocabulary listing phases of various decisional processes. It was originally created for AKN4EU specifications concerning documents pertaining to the ordinary legislative procedure, but it can be used for other purposes in the future, as a reference for phases of procedures of all nature – non legislative, legislative, internal, interinstitutional and judicial. It is part of the exchange between the institutions involved in the legal decision making process and the Publications Office of the European Union. It provides an authority code and the start-use date and a definition of each concept. The Procedure phase authority table is under governance of the Interinstitutional Metadata Maintenance Committee (IMMC) and maintained by the Publications Office of the European Union in the Metadata Registry (EU Vocabularies website).
