Can. 271

§1. Apart from the case of true necessity of his own particular church, a diocesan bishop is not to deny permission to clerics, whom he knows are prepared and considers suitable and who request it, to move to regions laboring under a grave lack of clergy where they will exercise the sacred ministry. He is also to make provision that the rights and duties of these clerics are determined through a written agreement with the diocesan bishop of the place they request.

§2. A diocesan bishop can grant permission for his clerics to move to another particular church for a predetermined time, which can even be renewed several times. Nevertheless, this is to be done so that these clerics remain incardinated in their own particular church and, when they return to it, possess all the rights which they would have had if they had been dedicated to the sacred ministry there.

§3. For a just cause the diocesan bishop can recall a cleric who has moved legitimately to another particular church while remaining incardinated in his own church provided that the agreements entered into with the other bishop and natural equity are observed; the diocesan bishop of the other particular church, after having observed these same conditions and for a just cause, likewise can deny the same cleric permission for further residence in his territory.
