[M. Thatcher]

Her attorneys are not very good or she is not listening to them because no, if an act is unconstitutional, not only does she not have the power, but she never had the power. The vow to find other means violates a principal called collateral estoppel. She cannot relitigate the same set of facts, and all legal arguments as to why she had these powers needed to be raised before the courts or she waived the argument.

Actually the state Supreme Court ruled she did not have the authority under two specific laws to extend the emergency after April 30 (court was asked by the 6th circuit to rule on the question).

So Gretchen says fine, I’ll impose the same regulations under different laws which I will find to fit. And I have 21 days to find new authorities because the Michigan Supreme Court ruling doesn’t take effect until then.

The point is that her attorneys were bound to raise those issues. Not having done so they waived the issue. Assuming the SC denies rehearing it's stare decisis.
