Legal scholar Ed Whelan argues that Judge Vaugh Walker should have been disqualified from the Prop 8 case now undergoing appeal - and that the decision he rendered in that case should be vacated:
Two weeks ago, former federal district judge Vaughn Walker, who ruled last summer in Perry v. Schwarzenegger that California’s Proposition 8 is unconstitutional, publicly disclosed for the first time that he has been in a same-sex relationship for the past ten years. A straightforward application of the judicial ethics rules compels the conclusion that Walker should have recused himself from taking part in the Perry case. Further, under well-established Supreme Court precedent, the remedy of vacating Walker’s judgment is timely and necessary.
... In taking part in the Perry case, Judge Walker was deciding whether Proposition 8 would bar him and his same-sex partner from marrying. Whether Walker had any subjective interest in marrying his same-sex partner — a matter on which Walker hasn’t spoken — is immaterial under section 455(a). (If Walker did have such an interest, his recusal also would be required by other rules requiring that a judge disqualify himself when he knows that he has an “interest that could be substantially affected by the outcome of the proceeding.”) Walker’s own factual findings explain why a reasonable person would expect him to want to have the opportunity to marry his partner: A reasonable person would think that Walker would want to have the opportunity to take part with his partner in what “is widely regarded as the definitive expression of love and commitment in the United States.” A reasonable person would think that Walker would want to decrease the costs of his same-sex relationship, increase his wealth, and enjoy the physical and psychological benefits that marriage is thought to confer.
