Brazil: Is marriage equality settled?

Looks like the news out of Brazil yesterday that the country's high court had effectively legalized marriage equality may not be the last word on the subject.

From the New York Times:

Brazil’s courts generally hew to the decisions of the National Council of Justice, which was created in 2004 and has functioned largely as a disciplinary body for the judiciary. But Congress could be another matter, as tensions simmer between Brazil’s legislative and judicial branches over the high court’s conviction of legislators involved in a vast vote-buying scandal.

Moreover, legislators who oppose same-sex marriage have recently grown more vocal in Congress. Marco Feliciano, a conservative evangelical preacher who now leads the lower house’s commission for human rights and minorities, has drawn criticism for comments that gay-rights activists call homophobic, but he has resisted pressure to step down from the post.

Same-sex marriage is already legal in 13 Brazilian states and in the capital federal district.
