If the Society and priests who minister to me are about to be declared schismatic and excommunicated, I want to know the rationale and justification for their consecrating bishops without a papal mandate. Canon law 1387 from the 1983 revised code of 1917 says this about those consecrations:
Can. 1387 Both the Bishop who, without a pontifical mandate, consecrates a person a Bishop, and the one who receives the consecration from him, incur a latae sententiae excommunication reserved to the Apostolic See. [For anyone who wants to read the law, the entire 1983 code is online here.]
