It's a debatable matter and probably won't be resolved by SB 58 or CADL v. MOC.
To solve it would mean a modification to MCL 123.1101 and/or another lawsuit. Total cost would likely exceed $20k.
Got some $ to help us start a lawsuit?
FWIW, I think chances of success under this lawsuit would be less than the CADL case as local school boards get their authority directly from the State Board of Education -- unlike CADL which was formed from Lansing and Ingham County.
If the CADL suit is lost -- this matter is almost assuredly lost as well. If the CADL suit is won, this is still an open question.
