Canon 1517

1. Before issuing an extra-judicial decree the authority is to

seek out the necessary information and proofs; hear or consult

those who should, by law, be heard or consulted; and also hear

directly whom the decree touches and especially those whose

rights can be injured. 2. The authority is to disclose to the

petitioner and also to the one who legitimately contradicts it

the information and proofs which can be known without danger of

public or private injury, and present the arguments from both

sides of the question, giving the possibility to respond to them

even by means of an advocate, within the period of time established by the authority itself.
