Canon 1513

1. No administrative act is revoked by a contrary law, unless

it is provided otherwise in the law itself or the law is enacted

by the authority superior to the one who issued the administrative act. 2. Unless it is expressly provided otherwise in the

law, an administrative act does not cease with the termination of

the authority of the one who issued it. 3. The revocation of

an administrative act by means of another administrative act of

competent authority takes effect only from the moment at which

the latter act has been made known to the person for whom it has

been given. 4. A dispensation which has successive applications ceases also by the certain and complete cessation of the

motivating cause. 5. An individual decree or precept ceases to

have force also through the cessation of the law for whose execution it has been issued; a singular precept ceases on the termination of the authority of the one who issued it, unless it has

been imposed through a legitimate document.
