You really never read the decisions?

In any case, the Archdiocese could have appealed the case since the act which vested all the authority in the parish council was contrary to canon law - see the St Nicholas case.

Archbishop Burke was fully aware of his predecessors in action on the matter.

Staying out of court was tacit endorsement of a de facto schism.

But your original assertion was that somehow this discredited the Archbishop, which it did not, or that the legal community was offended, which it was not.
