Code_of_Canon_Law

§2 Customs apart from the law, whether universal or particular, which have been in effect
hitherto, are retained.
Can. 6 §1 When this Code comes into force, the following are abrogated:
1° the Code of Canon Law promulgated in 1917;
2° other laws, whether universal or particular, which are contrary to the provisions of this Code,
unless it is otherwise expressly provided in respect of particular laws;
3° all penal laws enacted by the Apostolic See, whether universal or particular, unless they are
resumed in this Code itself;
4° any other universal disciplinary laws concerning matters which are integrally reordered by
this Code.
§2 To the extent that the canons of this Code reproduce the former law, they are to be assessed in
the light also of canonical tradition.
TITLE I: ECCLESIASTICAL LAWS
Can. 7 A law comes into being when it is promulgated.
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 m 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.
Can. 9 Laws concern matters of the future, not those of the past, unless provision is made in
them for the latter by name.
Can. 10 Only those laws are to be considered invalidating or incapacitating which expressly
prescribe that an act is null or that a person is incapable.
Can. 11 Merely ecclesiastical laws bind those who were baptised in the catholic Church or
received into it, and who have a sufficient use of reason and, unless the law expressly provides
otherwise, who have completed their seventh year of age.
Can. 12 §1 Universal laws are binding everywhere on all those for whom they were enacted.
