Rule 8.4New York Rules of Professional Conduct / ABA Model Rules
Misconduct
Rule Text
It is professional misconduct for a lawyer to: (a) violate or attempt to violate the Rules of Professional Conduct; (b) engage in illegal conduct that adversely reflects on the lawyer's honesty, trustworthiness or fitness; (c) engage in conduct involving dishonesty, fraud, deceit or misrepresentation; (d) engage in conduct that is prejudicial to the administration of justice.
What Constitutes a Violation
Rule 8.4 is the profession's general misconduct rule — the catchall that covers conduct not addressed by more specific rules. Subsection (b) reaches criminal conduct that reflects on fitness to practice law, even when the conduct is unrelated to law practice. Subsection (c) covers dishonesty and fraud in any context. Subsection (d) applies to conduct that prejudices the administration of justice broadly. Rule 8.4 is frequently charged alongside other rule violations when the underlying conduct involves dishonesty, criminality, or fundamental untrustworthiness. It is also the rule used to discipline attorneys for misconduct in private life that calls their fitness to practice into question.
Typical Discipline
Rule 8.4 violations span the full range of sanctions. Criminal convictions that trigger Rule 8.4(b) — particularly for crimes of dishonesty, violence, or moral turpitude — frequently result in immediate suspension or disbarment. Fraud and dishonesty violations under Rule 8.4(c) are treated seriously because they undermine the foundation of trust on which the attorney-client relationship depends. Rule 8.4 charges accompanying other violations contribute to more serious cumulative sanctions.
