New Mexico Judicial Discipline: The Judicial Standards Commission May Investigate and Adjudicate Without Masters Absent Unconstitutional Bias, and Repeated, Defiant Legal Error Can Constitute Willful Misconduct Warranting Removal

Introduction

In Re Detsoi (Supreme Court of New Mexico, July 10, 2026) arises from a petition for discipline filed by the New Mexico Judicial Standards Commission (the “Commission”) seeking the immediate and permanent removal of the Honorable Brent A. Detsoi, a McKinley County magistrate judge.

The Commission found that Respondent engaged in willful misconduct across thirteen cases by raising criminal jurisdiction sua sponte, informally confirming defendants’ Indian status, and then summarily dismissing prosecutions at various stages—often at arraignment—without sufficient notice and without a hearing. Evidence at the Commission hearing indicated Respondent may have dismissed as many as sixty-three prosecutions under similar circumstances and continued doing so despite appellate reversals and repeated warnings from judges, staff, and AOC personnel.

Respondent’s defense centered on two issues:

  • Procedural due process / state constitutional challenge: The Commission allegedly could not be impartial because it both investigated and adjudicated, engaged in “secret, ex parte communications” consistent with Rule jsc-15(G)(1) NMRA, and denied his motion to appoint masters.
  • Substantive limit on discipline: The charges allegedly reflected only legal error, which Respondent argued should be addressed by appeal rather than judicial discipline.

After ordering supplemental briefing on whether the Commission’s procedure is constitutional under the New Mexico Constitution, the Court granted the petition and imposed removal by order (Feb. 25, 2026), then issued this opinion to explain its reasoning.

Summary of the Opinion

The Court affirmed the Commission’s recommendation and held:

  • Commission procedure constitutional: Under Article VI, Section 32 of the New Mexico Constitution and federal due process, the Commission has wide discretion to either hold the hearing itself or appoint masters; combining investigative and adjudicative functions does not itself establish unconstitutional bias.
  • No basis to expand state due process here: Respondent failed to justify departing from federal doctrine (notably Withrow v. Larkin) under an interstitial analysis; neither Reid nor Riegger required a different result.
  • Legal error can be willful misconduct: Respondent’s argument that legal error cannot support discipline was foreclosed by In re Locatelli; repeated, intentional, defiant misapplication of law—especially as a pattern—may constitute willful misconduct.
  • Removal warranted: Given the pattern, escalation despite training, and credibility concerns paralleling In re Rodella, permanent removal was “more than sufficient.”

Analysis

Precedents Cited

1) New Mexico judicial discipline structure and review

  • State ex rel. N.M. Jud. Standards Comm'n v. Espinosa (2003-NMSC-017): Used to describe the Commission’s constitutional origin and role as an advisory body whose recommendations are reviewed by the Supreme Court, which has final authority. This case supports the Court’s repeated theme that the Court’s independent review is a structural safeguard against bias.
  • In re Rodella (2008-NMSC-050): Central authority for (a) the Court’s independent evaluation standard with deference to credibility findings, (b) the Commission’s discretion whether to appoint special masters, and (c) the proposition that combined functions are not inherently biased given confidentiality and the Court’s final review power. The opinion also supplies removal rationale grounded in patterns of misconduct, failure to correct after mentoring, and credibility deficits.
  • In re Castellano (1995-NMSC-007): Supplies multiple key principles: Commission proceedings must provide due process; procedural errors are reviewed for actual prejudice (harmless error framing); and the Court declined to restrict Commission flexibility in procedures, including masters’ appointment practices—even where masters were also Commission members. The case is also cited for the distinction between whether misconduct occurred and what sanction is appropriate.
  • In re Griego (2008-NMSC-020): Cited for de novo review of conclusions of law and discipline recommendations.
  • State ex rel. Child., Youth & Fams. Dep't v. Joseph M. (2006-NMCA-029): Quoted via In re Rodella for the meaning of “clear and convincing evidence.”
  • In re O'Dea (622 A.2d 507 (Vt. 1993)): Cited (through In re Castellano) for the idea that due process concerns are reduced when the administrative body is not the final decisionmaker.

2) Due process and combined investigative/adjudicative functions

  • Seidenberg v. N.M. Bd. of Med. Exam'rs (1969-NMSC-028): Establishes New Mexico’s longstanding administrative-law rule that the same body can charge and adjudicate without automatic disqualification; dual roles do not, “in itself,” violate due process.
  • Withrow v. Larkin (421 U.S. 35 (1975)): The foundational federal case creating a presumption of honesty and integrity in adjudicators and rejecting the idea that combining investigative and adjudicative powers is constitutionally forbidden absent a showing of intolerable risk (e.g., pecuniary interest, personal animus).
  • Knapp v. U.S. Dep't of Agric. (796 F.3d 445 (5th Cir. 2015)): Reinforces the mainstream federal view that dual roles alone do not show unconstitutional bias.

3) Unanimous national treatment in judicial discipline

  • Gentry v. Jud. Conduct Comm'n (612 S.W.3d 832 (Ky. 2020)); Adams v. Comm'n on Jud. Performance (897 P.2d 544 (Cal. 1995)); In re Zoarski (632 A.2d 1114 (Conn. 1993)): Each is cited as persuasive authority applying Withrow in the judicial discipline context to reject structural-bias claims based on combined functions.
  • In re Hanson (532 P.2d 303 (Alaska 1975)): Particularly influential because it (a) states the structural-bias argument had been rejected by all courts then considering it, (b) emphasizes the supreme court’s ultimate authority as a safeguard, and (c) rejects the claim that due process requires a commission to always appoint a master.
  • In re Del Rio (256 N.W.2d 727 (Mich. 1977)); In re Morrow (976 N.W.2d 644 (Mich. 2022)): Reinforce that “authority is legion” supporting combined functions in judicial fitness proceedings.

4) State constitutional “interstitial” departure analysis

  • State v. Crane (2014-NMSC-026) and State v. Gomez (1997-NMSC-006): Cited for the interstitial framework and grounds for departing from federal constitutional analysis.
  • Lujan Grisham v. Van Soelen (2023-NMSC-027): Noted for inviting reconsideration of the interstitial approach, though Respondent relied on it.
  • State v. Martinez (2021-NMSC-002): Respondent’s main analogy for expanding Article II, Section 18; the Court distinguished it because Martinez was driven by a substantial body of empirical research and broad legal developments, unlike Respondent’s sparse materials here.
  • Reid v. New Mexico Board of Examiners in Optometry (1979-NMSC-005): Treated as a bias-by-evidence case (a prejudicial statement suggesting prejudgment), not a structural combined-functions case.
  • New Mexico Board of Veterinary Medicine v. Riegger (2007-NMSC-044): Treated as a pecuniary-interest/appearance-of-bias problem involving costs and compensation that could create an objective belief of bias—again not a rule invalidating combined functions.
  • State ex rel. Hannah v. Armijo (1933-NMSC-087) and Rule 21-211(A)(3) NMRA: Used to explain the long-standing pecuniary-interest disqualification rule.

5) Legal error vs. willful judicial misconduct

  • In re Locatelli (2007-NMSC-029): The decisive New Mexico authority rejecting a categorical “legal error is only for appeals” defense; legal error can support discipline when it constitutes willful misconduct—intentional, knowing, generally in bad faith—and more than negligence.
  • In re Rodella (2008-NMSC-050) and In re Castellano (1995-NMSC-007): Cited for discipline often responding to patterns of behavior undermining integrity and independence of the judiciary.
  • In re Curda (49 P.3d 255 (Alaska 2002)) and Oberholzer v. Comm'n on Jud. Performance (975 P.2d 663 (Cal. 1999)): Quoted by Respondent for independence, but the Court highlights that their actual holdings support discipline for willful or patterned legal error (not blanket immunity).
  • In re Holien (612 N.W.2d 789 (Iowa 2000)): Cited (through a secondary source) for sanctioning patterns of procedural violations at arraignments.
  • State v. Cutnose (1974-NMCA-130) and State v. Verdugo (901 P.2d 1165 (Ariz. Ct. App. 1995)): Cited for the proposition that defendants bear the burden to show facts establishing an exception to state jurisdiction in Indian Country contexts.
  • State v. Gomez (2003-NMSC-012): Cited for the principle that pretrial dismissal is inappropriate if the State could reasonably assert additional evidence.

Legal Reasoning

1) Constitutional and statutory text: “may … or” means discretion

The Court anchors its procedural holding in the text of Article VI, Section 32, which provides that the Commission may order a hearing before itself, or appoint three masters “to hear and take evidence.” The Court reads this as broad discretion, reinforced by:

  • NMSA 1978, § 34-10-2.1(B)(3) (2023): masters appointed “if the commission deems it necessary or convenient.”
  • Rule jsc-4(G)(1) NMRA: same “necessary or convenient” standard.

The Court therefore treats Respondent’s request for a mandatory masters requirement as inconsistent with the constitution’s structure.

2) Due process: combined functions are not unconstitutional per se

On federal due process, the Court relies on the long-standing administrative law principle (in New Mexico and nationally) that a body can investigate and adjudicate without violating due process absent evidence of actual or inherently intolerable bias. The Court ties Seidenberg v. N.M. Bd. of Med. Exam'rs to Withrow v. Larkin, adopting Withrow’s presumption of integrity and insisting that structural claims must be supported by evidence.

Critically, Respondent conceded he did not claim actual bias and did not challenge the sufficiency of the evidence supporting the Commission’s factual findings. That posture made it especially difficult to translate an “appearance” argument into a constitutional defect.

3) Harmless error / prejudice requirement in Commission procedure challenges

The Court reiterates In re Castellano’s rule that procedural errors in Commission proceedings do not affect review “unless the errors actually prejudiced the respondent.” The opinion explicitly notes Respondent did not show (or even claim) prejudice from the Commission’s denial of masters—an independent barrier to relief even if one accepted an “appearance” critique.

4) State constitutional expansion rejected under interstitial analysis

Respondent urged the Court to “part company with Withrow” by expanding Article II, Section 18 due process. The Court distinguishes State v. Martinez—where extensive empirical research and widespread legal developments justified a broader state rule— from Respondent’s limited materials (three commentaries largely about confirmation bias).

Respondent also argued New Mexico’s cases emphasize “the appearance of complete fairness,” but the Court treats Reid v. New Mexico Board of Examiners in Optometry as an actual-evidence-of-bias case and New Mexico Board of Veterinary Medicine v. Riegger as a pecuniary-interest problem—neither supporting a categorical rule that dual functions require masters or violate Article II, Section 18.

5) Legal error can be misconduct when it becomes willful, patterned, and defiant

On the merits of discipline, the Court uses In re Locatelli to reject Respondent’s categorical immunity theory. The dividing line is not “legal error vs. no discipline,” but whether the conduct constitutes willful misconduct in office: improper and wrong conduct done intentionally, knowingly, and generally in bad faith—more than negligence.

The Court contrasts Locatelli—where the judge consulted and researched, and the record supported at most negligence—with Detsoi’s record (unchallenged factually) establishing: a repeated practice of sua sponte jurisdictional dismissals at arraignment, without hearings, continuing despite reversals and warnings.

The Court further underscores that jurisdictional exception claims typically require the defendant to carry a burden (State v. Cutnose) and that the State must have an opportunity to present evidence (citing State v. Gomez (2003-NMSC-012)). The mismatch between those principles and Respondent’s summary practices supports the conclusion that the error was not isolated or good-faith, but willful and systemic.

6) Why removal (not lesser discipline) was upheld

Following In re Rodella and In re Castellano, the Court treats removal as appropriate where a judge’s conduct threatens the integrity and independence of the judiciary—especially when misconduct persists despite training/mentoring and where the judge shows “defiance” rather than remorse and lacks credibility. The Court concludes those considerations applied “the same” here.

Impact

  • Procedural challenges to the Commission will face a high bar: This opinion consolidates New Mexico doctrine that the Commission’s combined functions are constitutionally acceptable and that appointment of masters is discretionary; future litigants will likely need concrete proof of actual bias or an inherently intolerable risk (e.g., pecuniary interest), plus a showing of prejudice under In re Castellano.
  • Limits on “legal error” defenses in discipline: Judges cannot treat appealability as a shield against discipline where there is clear and convincing evidence of a willful, patterned disregard of procedural requirements or fundamental rights. The opinion strengthens the practical reach of In re Locatelli by applying it to repeated jurisdictional dismissals.
  • Operational guidance for trial courts: The Court signals that sua sponte jurisdiction dismissals—especially at arraignment—without notice and hearing are highly vulnerable, and that jurisdictional determinations in Indian Country contexts ordinarily require a developed record and an opportunity for the State to be heard.
  • Institutional legitimacy: By emphasizing the Court’s final authority under Article VI, Section 32 and its independent record review, the opinion frames New Mexico’s model as structurally legitimate even while acknowledging that alternative procedures (e.g., using non-Commission masters) may be “wise” as a policy precaution.

Complex Concepts Simplified

  • Sua sponte: The judge raises an issue on the judge’s own initiative, not because a party filed a motion.
  • Masters (special masters): A panel (here, “three masters who are justices or judges of courts of record”) appointed to take evidence and report findings, instead of the Commission hearing the case itself.
  • Clear and convincing evidence: A heightened standard of proof—more than “preponderance,” less than “beyond a reasonable doubt”—leaving the factfinder with an abiding conviction the claim is true.
  • Willful misconduct in office: Not every mistake qualifies. Discipline requires intentional/knowing improper conduct (generally bad faith) that is more than negligence or mere judgment error.
  • Interstitial analysis: A method for deciding whether the state constitution provides broader protections than the federal constitution by examining federal law first and then identifying reasons to depart (e.g., flawed federal analysis, distinctive state characteristics).
  • Confirmation bias (as discussed): A tendency to interpret new information in ways that confirm an existing belief; Respondent cited this concept to argue that a body that investigates may become predisposed when later adjudicating. The Court held the cited materials were insufficient to overturn settled structural doctrine.

Conclusion

In Re Detsoi reinforces two practical rules in New Mexico judicial discipline:

  1. Procedure: Under Article VI, Section 32 and due process principles reflected in Seidenberg, Withrow, In re Rodella, and In re Castellano, the Commission may investigate and adjudicate and may deny a request for masters absent evidence of unconstitutional bias—and procedural complaints generally require a showing of prejudice.
  2. Substance: A judge’s “legal error” can become disciplinable willful misconduct when it is intentional, repeated, defiant, and contrary to basic procedural fairness—especially where it manifests as a pattern that undermines the judiciary’s integrity.

The opinion’s broader significance lies in its institutional message: judicial independence does not include a license to persist in systemic procedural violations, and New Mexico’s Commission-and-review-by-Supreme-Court structure remains constitutionally stable against structural-bias attacks.
