My translation of Tornielli’s piece:
The signatures of 500 people requesting the application of the Motu Proprio Summorum Pontificum, also in the Ambrosian diocese, have been delivered to the chancery of Milan. … As you might recall, a good part of the Diocese of Milan follows the Ambrosian Rite and formally in the papal document only the Roman Rite is cited (the head of the rite for Ambrosian rite is Card. Dionigi Tettamanzi). On the face of it, the derestriction would be applied only to parishes that follow the Roman Rite. Even in this matter, however, a notification from Msgr. Manganini, episcopale vicar, dodged the issue by sustaining that in the diocese there do not exist any groups attached the the old Rite. The position of the Curia of Milan roused up some tempers in the highest floors of the Vatican. Even if, formally it is on solid ground, in fact the decision of the Curia of Milan certainly does not show any understanding of the intention of the Pontiff. The more than 500 signatures were collected during the last weeks via the internet. Among these, the internet site totustuus, which promoted this initiative, reports that about half (47 percent to be precise) are of people who are less than 50 years.
You might remember there was some about this from Card. Castrillon Hoyos, which I posted about in the entry The correction of Milan. Tornielli said then:
Moreover, it seems to me that Cardinal Castrillòn, President of Ecclesia Dei recently had a conversation (I think by telephone) with one of those people in charge of the Ambrosian Rite, in the course of while he presented the diappointment of the Holy See for the non-application of the Motu Proprio in the Lombard capital.
