How The Court Could Rule

– A Broad Decision: The best, and most obvious, decision would be for the justices to follow the Constitution and the clear command of precedent and extend marriage equality to all fifty states. It is fairly likely, however, that at least one member of the majority will be too cautious to require Alabama to follow the Constitution, even if they are prepared to order California to do so. If the justices punt on the Alabama question, the important question is whether they hold that anti-gay laws are subject to “heightened scrutiny,” a skeptical kind of constitutional analysis that will make it very difficult for anti-gay discrimination to withstand court review in the future.

— A One-Off: The Ninth Circuit proposed a way to strike down Prop 8 while leaving most other states free to engage in marriage discrimination (the court said that voters were not permitted to withdraw the right to marry once it had been established by the state Supreme Court). The logic of the ruling was thus confined to California. Similarly, two of the Court’s most importantgay rights opinions relied on very narrow reasoning that advanced equality only incrementally. It is possible the justices will repeat this performance.

– Jurisdictional Dodges: In both cases, the Court could potentially rule that it lacks jurisdictionto hear the case, a decision that would cast a cloud of uncertainty over the rights of gay couples.

– A Stealth Attack: Several prominent conservatives are pushing a dangerous legal theory that would strike down DOMA on states’ rights grounds, and potentially endanger Social Security, veterans benefits and progressive taxation in the process.

– A Loss: Ultimately, however, it is important to remember that this is a severely conservative Court, and even so-called swing vote Justice Kennedy is a severely conservative justice. Equality could lose.

What To Expect From The Justices

– The Democratic Appointees: It would be very surprising if any of the Court’s four Democrats vote to uphold discrimination. While some commentators have noted Justice Ginsburg’s critical statements about Roe v. Wade — “It’s not that the judgment was wrong, but it moved too far, too fast” — this statement suggests Ginsburg might take an incremental approach, not that she will vote to uphold discrimination. Chance of pro-equality vote: more than 90 percent.

– Justice Alito: Alito is probably the toughest conservative questioner on the Court, and he has emerged as a strong advocate for whatever outcome conservatives prefer. Chance of pro-equality vote: less than one percent.

Surging Support For Marriage Equality

– Marriage Equality Has Strong Bipartisan Support: Retired Judge Vaughn Walker, the first judge to strike down Prop 8, is a Republican appointed to the bench by President George H.W. Bush. Three of the court of appeals judges that voted to declare DOMA unconstitutional areRepublicans. 131 top Republicans, including six former Republican governors, filed a brief supporting marriage equality.

The Constitution guarantees “the equal protection of the laws” — and that includes same-sex couples. As the Supreme Court has explained, this guarantee is most robust when applied to groups that experienced a “‘history of purposeful unequal treatment‘ or been subjected to unique disabilities on the basis of stereotyped characteristics not truly indicative of their abilities.” LGBT Americans undoubtedly fit this description, and thus neither DOMA nor Prop 8 can stand.
