In 2016, the American Bar Association House of Delegates added discrimination and harassment to the definition of professional misconduct. ABA Rule 8.4(g) specifically states:

“It is professional misconduct for a lawyer to: … (g) engage in conduct that the lawyer knows or reasonably should know is harassment or discrimination on the basis of race, sex, religion, national origin, ethnicity, disability, age, sexual orientation, gender identity, marital status or socioeconomic status in conduct related to the practice of law. This paragraph does not limit the ability of a lawyer to accept, decline or withdraw from a representation in accordance with Rule 1.16. This paragraph does not preclude legitimate advice or advocacy consistent with these Rules.”
