Background
Hon. Brent A. Detsoi served as a magistrate judge in McKinley County, New Mexico. Over an extended period, he dismissed as many as sixty-three criminal prosecutions by raising the question of tribal criminal jurisdiction sua sponte—often at arraignment—then informally confirming a defendant’s Indian status, and summarily dismissing the case without providing notice to the parties or holding a hearing. The New Mexico Judicial Standards Commission formally charged him based on thirteen such dismissals. Despite being reversed on appeal multiple times and being counseled, warned, and admonished by fellow judges, court staff, and Administrative Office of the Courts personnel, Detsoi continued the practice.
The Commission conducted a hearing, found willful misconduct in office, and recommended Detsoi’s immediate and permanent removal. The New Mexico Supreme Court ordered removal on February 25, 2026, and subsequently issued this opinion at the Commission’s request to explain the reasoning behind that order.
Detsoi raised two principal defenses. First, he argued that the Commission’s dual roles as investigator and adjudicator—combined with its failure to appoint a panel of masters to hear the charges—violated procedural due process under the New Mexico and federal constitutions. Second, he argued that his dismissals amounted to nothing more than legal error, which he contended cannot constitute willful misconduct and for which the proper remedy is appellate reversal, not judicial discipline. Notably, Detsoi did not contest the sufficiency of the evidence supporting the Commission’s factual findings.
The Court’s Holding
The Court rejected Detsoi’s due process challenge to the Commission’s combined investigatory and adjudicatory functions. Relying on Article VI, Section 32 of the New Mexico Constitution, decades of its own precedent—including In re Rodella (2008) and In re Castellano (1995)—and the United States Supreme Court’s decision in Withrow v. Larkin (1975), the Court held that combining investigative and adjudicative functions in an administrative body does not, of itself, violate due process absent evidence of actual or inherent bias. The Court further noted that the Commission’s authority is limited to recommending discipline; the Supreme Court independently reviews the record de novo and retains final decision-making authority, which serves as a significant structural safeguard against bias.
The Court also declined Detsoi’s invitation to construe New Mexico’s due process clause more broadly than its federal counterpart. Detsoi relied on three psychological and law review articles discussing confirmation bias, but the Court found that this slim body of literature fell far short of the extensive empirical scientific record that had justified an independent state constitutional departure in State v. Martinez (2021). The Court likewise distinguished Reid v. New Mexico Board of Examiners in Optometry (1979) and New Mexico Board of Veterinary Medicine v. Riegger (2007) as inapposite, holding that neither case displaced the core rule that a combined investigative-adjudicative structure is permissible absent unconstitutional bias.
Having rejected the procedural challenge, the Court affirmed the Commission’s finding of willful misconduct and upheld the sanction of permanent removal from office. The Court noted that Detsoi’s persistent dismissals continued despite repeated reversals and official warnings, supporting a clear-and-convincing-evidence finding of willful—rather than merely erroneous—conduct.
Key Takeaways
- A judicial disciplinary commission’s combined investigatory and adjudicatory functions do not violate due process under either the New Mexico Constitution or the federal Due Process Clause, so long as there is no evidence of actual or inherent bias and the state supreme court independently reviews the record.
- The decision whether to appoint masters is committed to the Commission’s discretion; a respondent judge seeking appointment bears the burden of demonstrating unconstitutional bias and resulting prejudice—neither of which Detsoi established.
- Three law review and psychology articles on confirmation bias are insufficient to justify departing from Withrow v. Larkin under New Mexico’s interstitial state constitutional analysis; a departure requires the kind of substantial empirical and legal consensus that supported the Court’s eyewitness-identification ruling in Martinez.
- A magistrate judge’s repeated, summary dismissal of criminal cases without notice or hearing—continued in defiance of appellate reversals and official warnings—constitutes willful misconduct in office warranting permanent removal, not merely an appealable legal error.
Why It Matters
This decision reaffirms the constitutional validity of New Mexico’s single-tiered judicial disciplinary structure—one shared by at least thirty-two other states—against procedural due process attack. Defense attorneys representing judges in disciplinary proceedings will face a high bar to disqualify a commission on structural grounds: they must produce evidence of actual or inherent bias and show that the bias caused prejudice, not merely point to the commission’s dual roles.
The case also clarifies the boundary between reviewable legal error and sanctionable judicial misconduct. A judge who persists in a pattern of legally defective rulings after repeated reversal and official warning can no longer credibly characterize the conduct as innocent mistake. For courts and commissions nationwide, In re Detsoi stands as a reminder that the appellate remedy of reversal is not the exclusive check on a judge whose misconduct is willful and recurrent.
