I think Whitmer can't order shut downs since her emergency order powers ran out.
Correct, but there's more. When the courts shut her down, she moved to using the health department to keep things locked down (masks, distancing, schools, etc) and then using MIOSHA to go around fining any business that did not comply for "health" violations.
Her actions the entire time have been political. This latest one was "recommending" schools close grades 6-12 as well as sports. That puts the school in a real no-win situation. Do they keep going because we know there's been no issues with sick kids or do they close because the Govt has recommended they do so along with their local health dept.
MI is clear proof that none of the restrictions/mandates make a bit of difference from a health perspective, other than a negative impact.
