Canon 664

1. The local hierarch may abide by the judgment about books

given by censors selected from the list drawn up by the synod of

bishops of the patriarchal Church, or the council of hierarchs,

or he may rely on others, according to his discretion; also a

special commission of censors may be set up for the local hierarch, the synod of bishops of the patriarchal Church, or the

council of hierarchs to consult. 2. The censors selected are

to be outstanding for their knowledge, right doctrine and prudence; in carrying out their office they are to give their judgment without any partiality but in accordance with Catholic doctrine as proposed by the Church's authentic magisterium. 3.

The censors must give their opinion in writing; if it is favorable, the hierarch may grant permission or approval, according to

his discretion, expressly in his own name; otherwise he must inform the author of the reasons for the refusal.
