Any priest has the right to celebrate the TLM any time he wants without the permission of the local ordinary. Summorum Po tificum made that quite clear.
The letter to the bishops makes it very clear that the local ordinary is still in charge:
“In conclusion, dear Brothers, I very much wish to stress that these new norms do not in any way lessen your own authority and responsibility, either for the liturgy or for the pastoral care of your faithful. Each Bishop, in fact, is the moderator of the liturgy in his own Diocese (cf. Sacrosanctum Concilium, 22: “Sacrae Liturgiae moderatio ab Ecclesiae auctoritate unice pendet quae quidem est apud Apostolicam Sedem et, ad normam iuris, apud Episcopum”).
Nothing is taken away, then, from the authority of the Bishop, whose role remains that of being watchful that all is done in peace and serenity.”
