9. The Supreme Pontiff has been pleased to confer on the Pontifical Commission Ecclesia Dei ordinary vicarious power for all matters within the bounds of its competence, especially in the matter of diligent observance and watchfulness in carrying out the provisions contained in the Apostolic Letter Summorum Pontificum(cf. art. 12).
10. § 1. Apart from the faculties previously granted by John Paul II and confirmed by Benedict XVI (cf. the Apostolic LetterSummorum Pontificum, art. 11 and art. 12), the Pontifical Commission exercises power of this sort also in deciding about recourses legitimately sent to it, as hierarchical Superior, against an individual administrative act of any Ordinary which appears contrary to the Apostolic Letter.
13. It is the task of Diocesan Bishops, according to the Codex Iuris Canonici, to be watchful about liturgical matters so that the common good may be preserved and so that all things may happen in their Dioceses worthily, peacefully and even-temperedly, according to the intent of the Roman Pontiff clearly expressed in the Apostolic Letter Summorum Pontificum.
If any controversy should arise, or well-founded doubt, about the celebration of the forma extraordinaria, judgment is reserved to the Pontifical Commission Ecclesia Dei.
