Can. 8 §1 Universal ecclesiastical laws are promulgated by publication in the ‘Acta Apostolicae Sedis’, unless in particular cases another manner of promulgation has been prescribed. They come into force only on the expiry of three months from the date appearing on the particular issue of the ‘Acta’, unless because of the nature of the case they bind at once, or unless a shorter or a longer interval has been specifically and expressly prescribed in the law itself.
§2 Particular laws are promulgated in the manner determined by the legislator; they begin to oblige one month from the date of promulgation, unless a different period is prescribed in the law itself.
