Canon 662

1. Ecclesiastical approval or permission to publish books may

be granted, unless expressly stated otherwise in the law, either

by the author's own local hierarch or by the hierarch of the

place of publication, or finally by a superior authority having

executive power over these persons or places. 2. In order to

publish writings dealing with religious and moral topics, members

of religious institutes need also the permission of their major

superior, according to the norm of their typicon or statutes.
