The Nevada Supreme Court ruled on a petition challenging judicial bias in a criminal case, granting partial relief to defendant Thomas Lamont Williams who sought to disqualify a district court judge. The court issued an opinion in *Williams v. Second Judicial District Court* (Nev. 2025) that addresses the presumption of innocence and standards for judicial disqualification in criminal proceedings.

Williams filed an original petition for a writ of mandamus challenging the Second Judicial District Court's denial of his motion to disqualify Judge Kathleen A. Sigurdson for bias. The petition also named Judge David A. Hardy as a respondent and sought reassignment of the criminal case to a different judge.

The case originated from a criminal proceeding where Williams filed a motion to sever, which the district court denied. According to the Supreme Court's opinion written by Justice Pickering, while the denial of the severance motion was "relatively routine," the order issuing that denial was "anything but," ultimately giving rise to the motion to disqualify the judge for judicial bias.

The Supreme Court noted that the case "addresses a writ petition implicating the presumption of innocence that underpins our criminal justice system." Justice Pickering, writing for a three-judge panel that included Justices Cadish and Lee, emphasized the court's task of "applying the standard for evaluating" allegations of judicial bias.

Williams was represented by Katheryn Hickman, Alternate Public Defender, and Thomas L. Qualls, Deputy Alternate Public Defender for Washoe County. The State of Nevada, as the real party in interest, was represented by Attorney General Aaron D. Ford, Washoe County District Attorney Christopher J. Hicks, and Appellate Deputy District Attorney Kevin Naughton.

The petition centered on allegations that Judge Sigurdson demonstrated bias in the criminal proceeding. While the specific details of the alleged bias are not fully outlined in the available portions of the opinion, the case appears to involve concerns about judicial conduct that Williams argued warranted disqualification and reassignment of his case.

Judicial disqualification motions in criminal cases require courts to balance several competing interests: ensuring fair trials free from judicial bias, maintaining public confidence in the judiciary, and preventing strategic manipulation of the court assignment process. Nevada law, like that in other states, establishes specific standards for when a judge must recuse themselves from a case.

The Supreme Court's mixed ruling suggests that while Williams raised legitimate concerns about judicial bias, not all aspects of his petition warranted relief. The partial grant indicates the court found merit in some of his arguments, while the partial denial suggests other claims were either unfounded or did not meet the legal standard for mandatory disqualification.

This case highlights the ongoing tension in criminal justice between defendants' rights to impartial judges and the practical necessity of avoiding frivolous disqualification motions that could disrupt court proceedings. The involvement of the Nevada Supreme Court in what began as a routine severance motion underscores the seriousness with which appellate courts treat allegations of judicial bias.

The opinion's emphasis on the presumption of innocence suggests that the underlying concern may relate to how the district court's handling of the case affected this fundamental principle of criminal law. When judges make statements or rulings that appear to prejudge a defendant's guilt, it can undermine the presumption of innocence that protects all criminal defendants.

For practitioners in Nevada's criminal justice system, this case serves as a reminder of the high standards expected of judicial conduct and the availability of appellate remedies when those standards may not be met. The mixed nature of the ruling also demonstrates that while courts take bias allegations seriously, petitioners must meet specific legal standards to obtain relief.

The case number 90071 has been assigned to this matter, and it represents part of the Nevada Supreme Court's ongoing oversight of the state's judicial system. The involvement of multiple judges as respondents and the designation of the State of Nevada as the real party in interest reflects the complex procedural nature of mandamus petitions challenging judicial conduct.

While the full implications of this ruling will depend on the complete text of the opinion and how lower courts interpret it, the case establishes important precedent for handling allegations of judicial bias in Nevada criminal proceedings. The partial relief granted to Williams suggests that courts will intervene when necessary to protect defendants' rights while maintaining appropriate deference to trial court discretion.
