This is the "he's gay so he must be biased" argument. Here's some of what the court said:
In fact, the Court observes that Judge Walker, like all judges, had a duty to preserve the integrity of the judiciary. Among other things, this means that if, in an overabundance of caution, he were to have disclosed intimate, but irrelevant, details about his personal life that were not reasonably related to the question of disqualification, he could have set a pernicious precedent. Such a precedent would be detrimental to the integrity of the judiciary, because it would promote, incorrectly, disclosure by judges of highly personal information (e.g., information about a judge’s history of being sexually abused as a child), however irrelevant or time-consuming. Contrary to the intent of Section 455, which was designed to preserve judicial integrity through practices of transparency, it is clear that fostering the practice of commencing a judicial proceeding with an extensive exploration into the history and psyche of the presiding judge would produce the spurious appearance that irrelevant personal information could impact the judge’s decision-making, which would be harmful to the integrity of the courts.797 (1)
Finally, the presumption that “all people in same-sex relationships think alike” is an unreasonable presumption, and one which has no place in legal reasoning. The presumption that Judge Walker, by virtue of being in a same-sex relationship, had a desire to be married that rendered him incapable of making an impartial decision, is as warrantless as the presumption that a female judge is incapable of being impartial in a case in which women seek legal relief. On the contrary: it is reasonable to presume that a female judge or a judge in a same-sex relationship is capable of rising above any personal predisposition and deciding such a case on the merits. The Motion fails to cite any evidence that Judge Walker would be incapable of being impartial, but to presume that Judge Walker was incapable of being impartial, without concrete evidence to support that presumption, is inconsistent with what is required under a reasonableness standard.
