STEVE INSKEEP, host:
Let's go next to California, where opponents of gay marriage are challenging a court ruling. Last year, a federal judge struck down California's ban on same-sex marriage. Now, the judge's critics contend he was biased because he is in a same-sex relationship.
Scott Shafer reports from our member station KQED in San Francisco.
SCOTT SHAFER: As the trial challenging California's Proposition 8 got underway last year, news reports began circulating that the federal judge overseeing the case was gay. It never came up during the proceedings. But a few months ago, as Judge Vaughn Walker was retiring from the bench, he told reporters he was in a long-term relationship with another man.
Mr. ANDREW PUGNO (Attorney): Judge Walker's 10-year same-sex relationship creates this unavoidable impression that he was just not the impartial judge that the law requires.
SHAFER: Andrew Pugno is one of the attorneys defending Prop 8. He says the issue here isn't Judge Walker's sexual orientation - not exactly - but rather that his relationship left him in the same shoes as the two same-sex couples who wanted to get married.
Mr. PUGNO: The motion is all about the fundamental principle that a judge really can't sit to hear their own case when they have an interest in the outcome.
SHAFER: In other words, Pugno and his legal team say, Walker had a vested interest in his own decision striking down Proposition 8.
But Kate Kendell, executive director of the National Center for Lesbian Rights, doesn't buy it.
Ms. KATE KENDELL (Executive Director, National Center for Lesbian Rights): There is absolutely not one scintilla of evidence that that fact of who he is biased him against the proponents.
SHAFER: Kendell notes our entire legal system rests on the idea that judges can keep an open mind and be objective about the issues before them.
Ms. KENDELL: And we cannot be about assuming that simply because a judge is of a certain sexual orientation, race or gender, he or she is incapable of actually doing the job of a judge.
Mr. RAY MARSHALL (Attorney): I think it'd be a step backwards.
SHAFER: Attorney Ray Marshall is a former chair of the California Bar Association. He fought for more diversity in the legal profession and on the bench. Those changes would be undermined, he says, by disqualifying a judge based on sexual orientation.
Marshall notes that one of the landmark cases in civil rights history - Brown v. the Board of Education desegregating public schools in the 1950s - was decided unanimously by an all-white Supreme Court.
Mr. MARSHALL: The presumption was that of course nine judges, all white men, will read the Constitution and make the decision fairly.
SHAFER: If we begin to challenge gay and lesbian judges based on their sexual orientation, says University of California Hastings Law Professor Rory Little, you'd have to treat straight judges, black judges and female judges the same way.
Professor RORY LITTLE (Law, University of California Hastings College of Law): The immediate reaction is: Oh, he's gay. Of course he ruled for the gay people. That's kind of like saying: Well, he's black and of course he ruled for the black people. It really is sort of insulting accusation.
SHAFER: And, Little says, there's not much case law to support this kind of challenge.
Prof. LITTLE: It begins to look like an act of desperation. Rather than fighting the case on the merits, they are looking for procedural reasons to challenge it.
SHAFER: That said, Professor Little and other legal scholars who think this challenge to the Proposition 8 decision has no merit also think the judge could have avoided these questions.
Deborah Rhode directs the Center on the Legal Profession at Stanford University's Law School.
Ms. DEBORAH RHODE (Director, Center on the Legal Profession, Stanford University): It would have served everyone's interest if Judge Walker had made disclosures at an earlier point. I think he might have anticipated that this would muddy the water.
SHAFER: The symbol of the American legal system is Lady Justice, balancing the scales of truth and fairness, blindfolded and unable to see who's before her. That premise will be tested in federal court here this morning.
