History. Committee comment amended October 17, 1996, effective January 1, 1997; entire Appendix repealed and readopted April 12, 2007, effective January 1, 2008; paragraph (c) amended and Adopted by the Court, En Banc, September 28, 2017, effective immediately. Subsection (i) added by Colorado Supreme Court, September 19, 2019
 Lawyers are subject to discipline when they violate or attempt to violate the Rules of Professional Conduct, knowingly assist or induce another to do so or do so through the acts of another, as when they request or instruct an agent to do so on the lawyer's behalf. Paragraph (a), however, does not prohibit a lawyer from advising a client concerning action the client is legally entitled to take.
 Many kinds of illegal conduct reflect adversely on fitness to practice law, such as offenses involving fraud and the offense of willful failure to file an income tax return. However, some kinds of offenses carry no such implication. Traditionally, the distinction was drawn in terms of offenses involving "moral turpitude." That concept can be construed to include offenses concerning some matters of personal morality, such as adultery and comparable offenses, that have no specific connection to fitness for the practice of law. Although a lawyer is personally answerable to the entire criminal law, a lawyer should be professionally answerable only for offenses that indicate lack of those characteristics relevant to law practice. Offenses involving violence, dishonesty, breach of trust, or serious interference with the administration of justice are in that category. A pattern of repeated offenses, even ones of minor significance when considered separately, can indicate indifference to legal obligation.
 A lawyer who, in the course of representing a client, knowingly manifests by word or conduct, bias or prejudice based upon race, gender, religion, national origin, disability, age, sexual orientation or socioeconomic status, violates paragraph (g) and also may violate paragraph (d). Legitimate advocacy respecting the foregoing factors does not violate paragraphs (d) or (g). A trial judge's finding that peremptory challenges were exercised on a discriminatory basis does not alone establish a violation of this Rule.
 A lawyer may refuse to comply with an obligation imposed by law upon a good faith belief that no valid obligation exists. The provisions of Rule 1.2(d) concerning a good faith challenge to the validity, scope, meaning or application of the law apply to challenges of legal regulation of the practice of law.
 Lawyers holding public office assume legal responsibilities going beyond those of other citizens. A lawyer's abuse of public office can suggest an inability to fulfill the professional role of lawyers. The same is true of abuse of positions of private trust such as trustee, executor, administrator, guardian, agent and officer, director or manager of a corporation or other organization.
[5A] Sexual harassment may include, but is not limited to, sexual advances, requests for sexual favors, and other verbal or physical conduct of a sexual nature that a reasonable person would perceive as unwelcome. The substantive law of employment discrimination, including antiharassment statutes, regulations, and case law, may guide, but does not limit, application of paragraph (i). “Professional activities” are not limited to those that occur in a client-lawyer relationship.
