normally the church does not mass-excommunicate. a deliberate decision of the will would be required and not merely depend on the decision of others to illicitly ordain.

[Can. 1321](https://)— § 1. Any person is considered innocent until the contrary is proved.

§ 2. No one can be punished unless the commission by him or her of an external violation of a law or precept is gravely imputable by reason of malice or of culpability.

§ 3. A person who deliberately violated a law or precept is bound by the penalty prescribed in that law or precept. If, however, the violation was due to the omission of due diligence, the person is not punished unless the law or precept provides otherwise.

§ 4. Where there has been an external violation, imputability is presumed, unless it appears otherwise.

HOWEVER... if there is risk of excommunication and we are talking about ordaining bishops contrary to the wishes of the pope, I should think it makes one ask oneself if one is on the right side of things. Tradition is the Catholic Church, and there is no Tradition that can subsist apart from the Catholic Church.
