The Tennessee Senate passed a bill Monday that would require Vanderbilt University to change its anti-bias policies with regard to student organizations, The Tennessean reported. Vanderbilt uses an "all comers" policy of the sort that has been upheld for public institutions by the U.S. Supreme Court. This means that to be recognized as an official student organization, groups cannot discriminate against any student who wants to participate. Some religious groups argue that this endangers their identities as those who do not share their faith could demand leadership positions in the groups. Defenders of such policies note that groups without official recognition can continue to limit membership and can engage in much campus activity, but typically must do so with their own funds rather than university funds. Lawmakers in Tennessee, prompted by the Vanderbilt case, are moving to bar public universities in the state from adopting policies similar to those of Vanderbilt (even though they haven't indicated any plans to do so). And on Monday, the Senate voted to add private institutions to the bill.
