Illicit Marijuana Use and Lack of Candor by a Judge Warrant a 60-Day Unpaid Suspension Under Indiana Judicial Discipline

Case: In the Matter of the Honorable John M. Plummer III, Judge of the Lawrence Superior Court I (Ind. May 20, 2026) (per curiam)

Posture: Judicial Discipline Action; decision on a jointly tendered “Statement of Circumstances and Conditional Agreement for Discipline.”

1. Introduction

This judicial-discipline decision addresses whether a sitting Indiana trial judge’s marijuana use—illegal in Indiana at the time— and his diminished candor during the Commission’s investigation warrant suspension. The Respondent, the Honorable John M. Plummer III, served as Judge of the Lawrence Superior Court I and presided over a general docket including criminal matters and domestic violence cases.

The key issues were (1) whether Respondent’s possession and ingestion of marijuana, coupled with observed impairment and erratic behavior, violated the Indiana Code of Judicial Conduct’s core duties of lawfulness and public confidence; and (2) whether Respondent’s contradictory, incomplete deposition testimony violated the duty of candor and cooperation with disciplinary authorities.

The Indiana Commission on Judicial Qualifications filed formal charges, but the matter came to the Indiana Supreme Court through a negotiated conditional agreement stipulating facts and recommending a sanction of a 60-day unpaid suspension. The Court accepted that sanction.

2. Summary of the Opinion

The Court found judicial misconduct based on Respondent’s marijuana ingestion over approximately four months, which coincided with visible impairment at a county council meeting and reports of erratic and agitated conduct. The Court also emphasized Respondent’s lack of forthrightness during the Commission’s investigation—particularly his contradictory and minimizing deposition testimony.

Respondent agreed he violated:

  • Rule 1.1 (compliance with the law and the Code);
  • Rule 1.2 (promoting public confidence; avoiding impropriety and its appearance); and
  • Rule 2.16(A) (cooperation; candor and honesty with disciplinary agencies).

Accepting the parties’ conditional agreement, the Court imposed a 60-day unpaid suspension beginning May 21, 2026, with automatic reinstatement July 20, 2026, and terminated the proceedings.

3. Analysis

3.1 Precedents Cited

In re King, 857 So.2d 432 (La. 2003)

The Court invoked In re King for the proposition that criminal conduct is “much more serious” when committed by a judge. This framing supports treating Respondent’s marijuana crimes not as private missteps but as institutional harms because judges embody the legal system’s authority and legitimacy.

In re Gilbert, 668 N.W.2d 892 (Mich. 2003), Weaver, J., dissenting

Quoting the dissent’s “hypocrisy” observation—judges “sit in judgment of others” for conduct they themselves commit—the Court reinforced that illegality by a judge uniquely undermines moral authority and perceived fairness, particularly salient here given Respondent’s criminal docket.

Matter of Oliver, 493 N.E.2d 1237 (Ind. 1986)

Oliver supplied an Indiana analogue: the conduct of judges and prosecutors can “bolster or damage public esteem for the system” in a way different from private attorneys. The Court used this to situate Respondent’s misconduct within Indiana’s tradition of heightened accountability for government legal actors charged with administering the law.

Matter of Sims, 665 N.E.2d 584 (Ind. 1996)

The Court cited Sims for the blunt institutional reality: when law enforcers break the law, the public questions whether the system deserves respect. This rationale directly supported a meaningful suspension—discipline aimed not merely at the individual but at preserving confidence in the system.

Matter of Cox, 275 N.E.3d 883 (Ind. 2026)

Cox provided the Court’s contemporary statement that judicial discipline is “not only remedial” but also intended to preserve judicial integrity and public confidence. The Court applied that remedial/public-protection lens to Respondent’s impairment episode and reputational harm, signaling that discipline need not mirror criminal punishment to be warranted.

Matter of Brown, 4 N.E.3d 619 (Ind. 2014)

Brown underscored that judges must cooperate truthfully during investigations; providing “factually inaccurate information” aggravates misconduct. This precedent shaped the Court’s treatment of Respondent’s contradictory deposition answers as an independent and serious violation of Rule 2.16(A), not a peripheral issue.

Matter of Cichowicz, 213 N.E.3d 1022 (Ind. 2023)

The Court relied on Cichowicz to calibrate sanction severity: suspensions longer than 30 days reflect “extremely serious” misconduct, “just shy” of what might warrant removal. This case thus served as a benchmark, justifying that 60 days is a major sanction while also explaining why the Court could still allow return to office.

Matter of Hawkins, 251 N.E.3d 1062 (Ind. 2025)

Hawkins supported the Court’s mitigation analysis: acceptance of responsibility and rehabilitative prospects may indicate the judge can “regain the public’s confidence.” Here, the Court referenced treatment, no substance use disorder diagnosis, no prior discipline, and eventual responsibility-taking to justify reinstatement after suspension rather than removal.

Matter of Meade, 200 N.E.3d 448 (Ind. 2023)

The Court drew from Meade the principle that conditional agreements often reflect negotiation and may warrant a less severe sanction than one imposed after a contested evidentiary hearing. This explicitly explains why the Court accepted the parties’ agreed sanction and signals an institutional preference for resolving discipline matters through negotiated stipulations when appropriate.

3.3 Impact

This opinion’s practical significance lies less in novel doctrine than in how it consolidates and applies existing disciplinary principles to illicit substance use and investigation candor:

  • Substance use by judges will be analyzed as institutional harm, not private behavior: The Court tied illegality to reputational damage and to the judge’s role in adjudicating criminal conduct, making “hypocrisy” and public-confidence concerns central to sanction selection.
  • Visible impairment and public-facing incidents matter: The county council meeting episode functioned as an evidentiary anchor for “appearance of impropriety” and public confidence concerns, suggesting that misconduct manifested in public or quasi-public settings can intensify sanctions.
  • Candor failures can materially increase sanction exposure: By foregrounding Rule 2.16(A) and analogizing to Matter of Brown, the opinion signals that contradictory testimony and minimization during investigation may be treated as a distinct and serious violation—potentially pushing conduct into “extremely serious” territory.
  • Negotiated discipline remains influential: The explicit reliance on Matter of Meade indicates the Court will continue to treat conditional agreements as worthy of deference (though not automatic acceptance), which may encourage early candor and stipulations in future cases.
  • Mitigation is framed in terms of “regaining public confidence”: Treatment, assessment, lack of prior discipline, and acceptance of responsibility mattered because they supported future trustworthiness, not merely sympathy for personal hardship.

4. Complex Concepts Simplified

“Appearance of impropriety” (Rule 1.2)
Even if a judge could argue no case was directly affected, conduct that reasonably makes the public suspect unfairness, bias, or unfitness can violate the Code. The judiciary depends on trust; perceived wrongdoing can be as damaging as proven case-specific harm.
Judicial discipline is “remedial”
The goal is not primarily to punish like a criminal sentence. It is to protect the public, safeguard the courts’ integrity, and ensure confidence in the judiciary. Sanctions are calibrated to restore trust and prevent recurrence.
Rule 2.16(A) duty of candor and cooperation
Judges must be truthful and forthcoming with disciplinary investigators. Incomplete answers, contradictions, and minimization can themselves constitute misconduct, because they obstruct oversight and suggest the judge cannot be trusted to self-report or comply with ethical obligations.
“Conditional agreement for discipline”
A negotiated resolution where the judge and the Commission stipulate to facts and propose a sanction. The Supreme Court still decides whether to accept it, but it may treat the negotiated nature as a reason not to impose an even harsher sanction that might follow a contested hearing.

5. Conclusion

The Indiana Supreme Court disciplined Judge Plummer for illicit marijuana use that coincided with observed impairment and erratic behavior, and for a separate, serious failure of candor during the Commission’s investigation. Applying established principles that judicial discipline protects public confidence, and guided by benchmarks for “extremely serious” misconduct, the Court approved a negotiated 60-day unpaid suspension with automatic reinstatement.

The decision reinforces two enduring themes in judicial ethics: (1) criminal conduct by a judge is uniquely corrosive to the legitimacy of the courts; and (2) honesty and full cooperation with disciplinary authorities are non-negotiable, with evasiveness treated as misconduct in its own right.
