The Supreme Court heard arguments regarding same-sex marriage for a second day Wednesday, looking at the case of Windsor v. United States and the Defense of Marriage Act. The case involves a lesbian couple married in Canada that moved to New York where one partner died, and because the pair was never legally married in the eyes of the federal government, the partner pays taxes for the house she was left that a opposite-sex partner would not pay for.

The attorney for the plaintiff intends to argue that the 14th amendment guarantees all citizens equal protection and that the government has to have a “good reason” to distinguish between gay and straight couples.

On ‘Real News‘ Wednesday the panel discussed what that “good reason” could be, what implications may come if the court declares the government prohibiting same-sex marriage unconstitutional, and what the government is doing in the marriage business in the first place.
