After a court battle that lasted more than seven years, Michigan teachers will get their money back. Money was collected under a 2010 law that required teachers and others to contribute 3 percent of their salaries toward their retirement health care. That was before 2013 and before a legal battle that threw it into an escrow account, which has since grown to $550 million. An order issued by the supreme court agreed that the money had been collected unconstitutionally.
