Supporters and opponents of marriage equality gathered on Tuesday in front of the Supreme Court, for the first day of hearings on Proposition 8, California's ban on same-sex marriage.

On Wednesday, the Supreme Court will evaluate the Defense of Marriage Act, the federal law preventing legally married gay couples from receiving the same benefits married straight couples receive, according to the Associated Press.

Lines developed at the Supreme Court days ahead of the cases.
