Legislative functions are delegated to the unicameral Pontifical Commission for Vatican City State, led by the President of the Pontifical Commission for Vatican City State. Its seven members are cardinals appointed by the Pope for terms of five years. Acts of the commission must be approved by the Pope, through the Holy See's Secretariat of State, and before taking effect must be published in a special appendix of the "Acta Apostolicae Sedis". Most of the content of this appendix consists of routine executive decrees, such as approval for a new set of postage stamps.
