Who holds the taxing power of the school systems not the schools themselves certainly, if so why does the state always
bail out the school systems as Detroit is a good example of that.
What's odd is that the MI SC and CoA have both previously ruled that school districts ARE quasi-municipal units of government. Here are some examples:
Supreme Court of Michigan: http://law.justia.com/cases/michigan/supreme-court/1960/359-mich-478-2.html
Michigan Court of Appeals: http://www.leagle.com/decision/197453951MichApp488_1471/DETROIT%20BD.%20OF%20EDUC.%20v.%20MICH.%20BELL%20TEL.%20CO
School districts have been classified as municipal corporations in Michigan for some 95 years. School District No 4 of the Township of Marathon v Gage, 39 Mich. 484 (1878); Attorney General, ex rel McRae v Thompson, 168 Mich. 511; 134 NW 722 (1912); Hall v Ira Twp, 348 Mich. 402; 83 N.W.2d 443 (1957); Rasmussen v Lincoln Park School District, 4 Mich.App. 278; 144 N.W.2d 644 (1966).
And here's an AG opinion for good measure: http://www.ag.state.mi.us/opinion/datafiles/1990s/op10026.htm
A public school academy is defined as a "public school" and a "governmental agency." Section 501
Also, this opinion (you have to read down it pretty far. It discusses taxation and appropriations for schools). http://www.ag.state.mi.us/opinion/datafiles/1960s/op04181.pdf
"In Michigan the law is settled that school districts are local state agencies of legislative creation...Further, the boards of education of school districts have only such powers as are expressly or by reasonably necessary implication conferred upon them by statute." Obviously they state legislature has not specifically exempted them from law regarding firearms preemption.
So how three anti-gun justices can say otherwise is baffling.
