Canon 6

Can. 6 §1. When this Code takes force, the following are abrogated:
1° the Code of Canon Law promulgated in 1917;
2° other universal or particular laws contrary to the prescripts of this Code unless other provision is expressly made for particular laws;
3° any universal or particular penal laws whatsoever issued by the Apostolic See unless they are contained in this Code;
4° other universal disciplinary laws regarding matter which this Code completely reorders.

Can. 6 §2. Insofar as they repeat former law, the canons of this Code must be assessed also in accord with canonical tradition.
