Curious you should neglect Archbishop Rigali since he is the person who actually began the response to the lay board's actions.
And my opinion, from the appearance of the original documents, is still that the lay board violated the corporate articles by the series of by-law revisions they engaged in. Those revisions were not legal.
They really are personally financially liable for their actions.
The diocese could drop the legal hammer any time they are in the mood and every judge in the state of Missouri would rule against the lay board.
So, instead of doing that, he decides to keep Catholics away from the sacraments?
If it's such a slam dunk, let him do it.
