§1. Whenever a person considers himself or herself aggrieved by a decree, it is particularly desirable that the person and the author of the decree avoid any contention and take care to seek an equitable solution by common counsel, possibly using the mediation and effort of wise persons to avoid or settle the controversy in a suitable way.
§2. The conference of bishops can determine that each diocese establish in a stable manner an office or council whose function is to seek and suggest equitable solutions according to the norms determined by the conference. If the conference has not ordered this, however, the bishop can establish a council or office of this kind.
§3. The office or council mentioned in §2 is especially to be of assistance when the revocation of a decree has been requested according to the norm of can. 1734 and the time limits for making recourse have not elapsed. If recourse has been proposed against a decree, however, the superior who deals with the recourse is to urge the person making recourse and the author of the decree to seek a solution of this kind whenever he sees hope of a favorable outcome.
