As I forgot to mention on Friday, a US district judge ruled that Michigan's Marriage Amendment is unconstitutional and that Michigan does not have the right to ban same-sex marriage.
Many Michigan residents have religious convictions whose principles ... inform their own viewpoints about marriage. Nonetheless, these views cannot strip other citizens of the guarantees of equal protection under the law. The same Constitution that protects the free exercise of one's faith in deciding whether to solemnize certain marriages rather than others, is the same Constitution that prevents the state from either mandating adherence to an established religion ... or enforcing private moral or religious beliefs without an accompanying secular purpose.
So it was a great win for marriage equality, hooray, yay, etc. But. The decision happened after 5pm, and most offices around Michigan had closed. So marriage equality was legal, but no one could get married that day, and no courts could appeal the decision. The state's Attorney General, Bill Schuette (R), acted as fast as possible to put the kibosh onto same-sex marriage, but he didn't act immediately and so, on Saturday morning, 323 couples got married. Those people may or may not be legally married; Michigan's governor, Rick Snyder (R), has yet to act on the issue. What has happened is that a different court has put a stay on the ruling and so no same-sex marriages can occur in Michigan.
Where is US marriage equality at, as of this week
There are 16 states wherein marriage equality is legal and being carried out; in Illinois it is currently legal but will not be carried out until June. The District of Columbia is also a zone wherein it is legal and able to be carried out. At the federal level, marriage equality is fully recognized: a same-sex couple married in 16 states (or DC) who moves to one of the other 34 (as of June, 33) states legally is still a married couple. Those 34 states are trying to figure out how to deal with this. In 5 of those states, legal challenges have already been decided against anti-same-sex marriage laws, but subsequent court decisions very quickly made it so that new marriages could not happen. Michigan is the latest in this series of "You can marry now... just kidding, not yet" decisions that have occurred in the past three months.
EDITED: Because I had OHIO in the title and not MICHIGAN. ... Sorry everyone I apparently am not awake.
