Enforcing Civility and Fitness: The ODC’s Amended Disciplinary Complaint Against Mark E. Anderson Under MRPC 3.1, 3.5, and 8.4

Enforcing Civility and Fitness: The ODC’s Amended Disciplinary Complaint Against Mark E. Anderson Under MRPC 3.1, 3.5, and 8.4

Important procedural note: Although the source is labeled as an “Opinion,” the text provided is an Amended Complaint filed by the Montana Office of Disciplinary Counsel (ODC) on October 29, 2025, with leave of the Commission on Practice granted October 15, 2025, in ODC File No. 24-056, Supreme Court Cause No. PR 25-0746. It is a charging document, not a judicial opinion or final decision. No new precedent or binding rule is established at this stage. What follows is a comprehensive analysis of the allegations, the rules invoked, and their implications within Montana’s attorney-discipline framework.

Introduction

This disciplinary matter arises out of contentious litigation surrounding the estate planning, guardianship, and probate affairs of the mother of Respondent, attorney Mark E. Anderson (admitted to the Montana bar in 1997). According to the Amended Complaint, a February 2024 grievance alleged malpractice and constructive fraud after Respondent quitclaimed his mother’s property to himself for no consideration. The ensuing disputes allegedly prompted a pattern of abusive and disruptive conduct in court filings and proceedings, as well as off-court conduct that culminated in a disorderly conduct charge and guilty plea in March 2024.

The Montana Office of Disciplinary Counsel now charges that Anderson’s conduct violated three core provisions of the Montana Rules of Professional Conduct (MRPC):

  • Rule 3.1 (Meritorious Claims and Contentions), focusing on filings and positions asserted for harassment, delay, or leverage;
  • Rule 3.5 (Impartiality and Decorum of the Tribunal), prohibiting conduct intended to disrupt a tribunal;
  • Rule 8.4(b) and (d) (Professional Misconduct), addressing criminal acts reflecting adversely on fitness, and conduct prejudicial to the administration of justice.

The Complaint emphasizes allegedly derogatory and profane remarks directed at the presiding judge, opposing counsel, and family members in court submissions, as well as disruptive conduct at a nursing facility. It seeks formal adjudication before the Commission on Practice, findings and recommendations to the Montana Supreme Court, and the imposition of appropriate discipline with costs.

Summary of the Filing

Because this is an Amended Complaint—not a judicial opinion—there are no findings of fact or conclusions of law at this time. The ODC’s theory is as follows:

  • Count One alleges violations of MRPC 3.1 and 3.5. While acknowledging that Respondent may have had legitimate legal issues, the ODC contends the defense strategy “consisted primarily” of derogatory attacks against the judge, counsel, and family, even after court warnings, thereby constituting harassment (Rule 3.1) and disruption of the tribunal (Rule 3.5).
  • Count Two alleges violations of MRPC 8.4(b) and (d). The ODC asserts that Respondent’s guilty plea to disorderly conduct, arising from threatening and disruptive behavior at a nursing home, reflects adversely on fitness to practice (8.4(b)), and that his litigation behavior unnecessarily delayed and burdened the proceedings, prejudicing the administration of justice (8.4(d)).

Requested relief: Citation to Respondent; a formal hearing before an Adjudicatory Panel of the Commission on Practice; findings and recommendations to the Montana Supreme Court; and appropriate discipline including costs and expenses.

Analysis

Procedural posture and forum

The Commission on Practice of the Montana Supreme Court oversees formal attorney discipline. The ODC prosecutes the case; the Adjudicatory Panel conducts hearings and issues findings and recommendations to the Montana Supreme Court. Ultimately, the Supreme Court imposes any discipline. While the Amended Complaint references the oath of admission and Chapter 61, Title 37, MCA (governing the professions and the discipline framework), the operative standards are the Montana Rules of Professional Conduct adopted by the Court.

Authorities cited or relied upon in the Complaint

  • Montana Rules of Professional Conduct
    • MRPC 3.1: Prohibits defending a proceeding or asserting or controverting an issue for harassment, delay, to advance non-meritorious contentions, or solely to gain leverage (the Complaint references 3.1(a)(2)).
    • MRPC 3.5: Prohibits conduct intended to disrupt a tribunal.
    • MRPC 8.4(b): Makes it professional misconduct to commit a criminal act reflecting adversely on the lawyer’s honesty, trustworthiness, or fitness.
    • MRPC 8.4(d): Prohibits conduct prejudicial to the administration of justice.
  • Title 37, Chapter 61, Montana Code Annotated: Cited in the oath-of-admission context to underscore the professional standards to which Montana attorneys are bound.

Notably, the Amended Complaint does not cite judicial precedents by name. Instead, it pleads specific rule violations grounded in asserted facts, a common approach in disciplinary pleadings.

Legal reasoning implicit in the ODC’s pleading

Although a complaint is not a reasoned opinion, the charging theory is clear and tracks the elements of the cited rules:

  • MRPC 3.1 (Harassment/Leverage vs. Merits): The ODC alleges that, even if legitimate legal grievances existed concerning guardianship and probate management, Respondent’s filings relied largely on abusive epithets and unfounded accusations against the court, counsel, and family members. If proven, that would support the conclusion that filings were used to harass, delay, or gain leverage rather than to present grounded legal contentions—conduct prohibited by Rule 3.1.
  • MRPC 3.5 (Decorum and Disruption): The Complaint asserts a “consistent practice” of derogatory statements “in nearly every filing and appearance,” despite judicial warnings. Persistently injecting scurrilous, inflammatory material into court submissions and proceedings can constitute intentional disruption of the tribunal’s processes—precisely what Rule 3.5 forbids.
  • MRPC 8.4(b) (Criminal act reflecting on fitness): Respondent allegedly engaged in threatening and disruptive behavior at a nursing home, was trespassed, and pled guilty to disorderly conduct in March 2024. The ODC contends this demonstrates an inability to control temper and emotions, reflecting adversely on fitness to practice. Although disorderly conduct is not a crime of dishonesty, Rule 8.4(b) is broader: the act need only “reflect adversely on fitness.” If the behavior shows poor judgment, lack of self-control, or disregard for lawful authority in a way that carries over to professional obligations, it can trigger 8.4(b).
  • MRPC 8.4(d) (Prejudice to the administration of justice): The alleged pattern of invective-laden pleadings and courtroom behavior purportedly caused delay, extra cost, and friction that impaired the efficient and fair administration of the guardianship/probate litigation. That is the core target of subsection (d).

The Complaint also states that Respondent continued the conduct “even after warnings from the Court,” which—if proven—would aggravate the seriousness of the misconduct by showing disregard for judicial authority and the inability or unwillingness to correct course when cautioned.

What is not charged but is contextually relevant

The disciplinary narrative begins with allegations that Respondent quitclaimed his mother’s property to himself for no consideration and that a malpractice/constructive fraud complaint was filed in February 2024. The ODC’s pleading here, however, is tightly limited to litigation conduct (Rules 3.1, 3.5) and off-court criminal behavior (8.4(b), (d)). It does not charge, for example:

  • Rule 8.2(a) (false statements about judges) for the alleged accusations of bias and vulgar name-calling directed at the presiding judge;
  • Rule 4.4(a) (no substantial purpose other than to embarrass, delay, or burden a third person) for alleged personal attacks on family and counsel;
  • Rules 1.7/1.8 or related fiduciary-duty rules in connection with the property transaction.

This focused charging strategy suggests that, at least at this juncture, the ODC is prioritizing conduct that directly undermines tribunals and the justice system’s functioning, as well as the fitness concerns evidenced by a criminal conviction.

Potential defenses and counter-arguments

  • First Amendment considerations: Lawyers do not forfeit free speech rights, but when acting in or in relation to judicial proceedings, their speech is subject to professional regulation aimed at protecting the administration of justice. The boundary between protected “rhetorical hyperbole” and sanctionable disruption or knowingly false attacks is fact-intensive. Respondent could argue that some statements were opinion, truthful, or made in the course of zealous advocacy. Whether such arguments prevail depends on context, veracity, and effect on the proceedings.
  • Merits vs. methods: Respondent may contend that his underlying legal positions were non-frivolous and that any intemperate language did not convert meritorious contentions into violations of Rule 3.1. ODC’s position is that the “primary” defense method was harassment rather than legal argument—an assertion that will be tested against the record.
  • Fitness nexus for 8.4(b): The defense might argue that a misdemeanor disorderly conduct conviction arising from a personal family crisis lacks a sufficient nexus to professional fitness. ODC counters that self-control, judgment, and respect for institutional order are core lawyering competencies.
  • Mitigation: Stress from a parent’s decline, familial conflict, lack of prior discipline, remorse, corrective action, or treatment for underlying causes (e.g., counseling) can mitigate sanctions, even if rule violations are found. Conversely, persistence after judicial warnings could be treated as aggravation.

Likely analytical framework at the hearing stage

At a contested hearing before the Commission on Practice, the ODC bears the burden of proof (in many jurisdictions, and typically in Montana discipline, by clear and convincing evidence) to establish the charged violations. If violations are found, sanction analysis generally follows the ABA Standards for Imposing Lawyer Sanctions, considering:

  • Duties violated (to the legal system, the profession, the public);
  • Mental state (intentional, knowing, negligent);
  • Actual or potential injury (to the proceedings, reputation of the judiciary, parties, or the public);
  • Aggravating and mitigating factors (pattern of misconduct, prior discipline, refusal to acknowledge wrongdoing, victim vulnerability, cooperation, remorse, personal or emotional problems, etc.).

Sanctions can range from admonition or public censure to suspension or disbarment. Cases driven by repeated, defiant, and disruptive conduct toward a tribunal—especially in defiance of warnings—often draw meaningful suspension. Documented mitigation and rehabilitation can materially affect outcome and sanction length.

Impact and signals for the bar

Though not a final decision, this Amended Complaint sends several clear signals to Montana practitioners:

  • Incivility is not a litigation strategy. Persistently abusive and profane filings aimed at judges, counsel, or parties invite Rule 3.1 and 3.5 scrutiny. Even if meritorious issues exist, an ad hominem “strategy” can independently violate the rules.
  • Fitness is holistic. Off-court criminal conduct, even outside a client matter, can implicate 8.4(b) if it bears on a lawyer’s judgment, emotional regulation, or respect for legal institutions.
  • Warnings matter. Continuing misconduct after judicial admonitions aggravates the case and can push sanctions upward.
  • Self-representation does not immunize conduct. Lawyers appearing as parties are still subject to the MRPC; the rules regulate the professional’s conduct, not only the attorney-client relationship.
  • Cost to the system is sanctionable harm. Delays, needless expense, and burdens on court administration are recognized injuries under 8.4(d).

Complex Concepts Simplified

  • MRPC (Montana Rules of Professional Conduct): Ethics rules adopted by the Montana Supreme Court that govern the behavior of lawyers. They address duties to clients, courts, third parties, the public, and the profession.
  • Rule 3.1 (Meritorious Claims/Contentions): You cannot file pleadings or take positions solely to harass, delay, or gain leverage. Even a good claim must be pursued with appropriate means.
  • Rule 3.5 (Decorum of the Tribunal): You must not engage in conduct intended to disrupt a court—this covers filings and in-court behavior that undermine orderly proceedings.
  • Rule 8.4(b) (Criminal Acts Reflecting on Fitness): Not every misdemeanor triggers discipline, but those showing poor judgment, lack of self-control, or disrespect for law can.
  • Rule 8.4(d) (Prejudicial to Administration of Justice): Conduct that hampers the fair and efficient functioning of courts—causing needless delays or expenses—is sanctionable.
  • Commission on Practice: The body that conducts disciplinary hearings in Montana. It hears evidence, makes findings, and recommends sanctions to the Montana Supreme Court, which issues the final order.
  • “Trespassed from the facility”: The nursing home issued a no-trespass directive; violating or disregarding it can lead to criminal charges like disorderly conduct.
  • Standard of proof: In attorney discipline, the charging authority typically must prove violations by “clear and convincing evidence,” a standard higher than “preponderance” but lower than “beyond a reasonable doubt.”

Conclusion

This Amended Complaint does not establish new legal precedent; rather, it illustrates the ODC’s application of well-settled professional norms to alleged conduct that, if proven, crosses the line from zealous advocacy to harassment and disruption, and from personal crisis to fitness-impairing criminality. The case underscores four core points for Montana practitioners: civility is obligatory; filings are not vehicles for invective; off-bench misconduct can affect licensure; and ignoring judicial warnings escalates disciplinary risk.

As the matter proceeds, the adjudicatory focus will likely center on whether the ODC can prove a sustained pattern of abusive litigation tactics and a fitness-implicating criminal episode; whether any legitimate legal arguments were obscured by improper methods; and how aggravation and mitigation balance out under the sanction analysis. Whatever the outcome, the filing itself is a cautionary account of how quickly family-driven disputes can devolve into conduct that implicates Rules 3.1, 3.5, and 8.4—rules designed to protect the integrity of tribunals, the profession, and the public’s trust in the justice system.
