A possible court battle may occur on University's right to grant same-sex benefits to its employees. Proposal 2 amended the state constitution to ban gay marriage or similar unions, meaning that same-sex partnerships can't be recognized as equal to marriage in the state. Robert Sedler, a professor of constitutional law at Wayne State University, said it will be unclear whether the amendment legally bans any domestic partner benefits until a state court provides a ruling. If courts rule that it does, he said, the University's last line of defense would be to argue that, as a constitutionally autonomous institution, it is exempt from the amendment.
