RPC 8.1-8.5

An applicant for admission to the bar, or a lawyer in connection with a bar admission application or in connection with a disciplinary matter, shall not:
(a) knowingly make a false statement of material fact; or
(b) fail to disclose a fact necessary to correct a misapprehension known by the person to have arisen in the matter, or knowingly fail to respond to a lawful demand for information from an admissions or disciplinary authority, except that this Rule does not require disclosure of information otherwise protected by RPC 1.6.

(a) A lawyer shall not make a statement that the lawyer knows to be false or that is made with reckless disregard as to its truth or falsity concerning the qualifications or integrity of the following persons:
(1) a judge;
(2) an adjudicatory officer or public legal officer; or
(3) a candidate for election or appointment to judicial or legal office.
(b) A lawyer who is a candidate for judicial office shall comply with the applicable provisions of the Code of Judicial Conduct.

(a) A lawyer who knows that another lawyer has committed a violation of the Rules of Professional Conduct that raises a substantial question as to that lawyer's honesty, trustworthiness, or fitness as a lawyer in other respects, shall inform the Disciplinary Counsel of the Board of Professional Responsibility.
(b) A lawyer who knows that a judge has committed a violation of applicable rules of judicial conduct that raises a substantial question as to the judge's fitness for office shall inform the Disciplinary Counsel of the Board of Judicial Conduct.
(c) This Rule does not require disclosure of information otherwise protected by RPC 1.6 or information gained by a lawyer or judge while serving as a member of a lawyer assistance program approved by the Supreme Court of Tennessee or by the Board of Professional Responsibility.

It is professional misconduct for a lawyer to:
(a) 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;
(b) commit a criminal act that reflects adversely on the lawyer's honesty, trustworthiness, or fitness as a lawyer in other respects;
(c) engage in conduct involving dishonesty, fraud, deceit, or misrepresentation;
(d) engage in conduct that is prejudicial to the administration of justice;
(e) state or imply an ability to influence a tribunal or a governmental agency or official on grounds unrelated to the merits of, or the procedures governing, the matter under consideration;
(f) knowingly assist a judge or judicial officer in conduct that is a violation of applicable rules of judicial conduct or other law; or
(g) knowingly fail to comply with a final court order entered in a proceeding in which the lawyer is a party, unless the lawyer is unable to comply with the order or is seeking in good faith to determine the validity, scope, meaning, or application of the law upon which the order is based.

(a) Disciplinary Authority. A lawyer admitted to practice in this jurisdiction is subject to the disciplinary authority of this jurisdiction, regardless of where the lawyer's conduct occurs. A lawyer not admitted in this jurisdiction is also subject to the disciplinary authority of this jurisdiction if the lawyer provides or offers to provide any legal services in this jurisdiction. A lawyer may be subject to the disciplinary authority of both this jurisdiction and another jurisdiction for the same conduct.
(b) Choice of Law. In any exercise of the disciplinary authority of this jurisdiction, the rules of professional conduct to be applied shall be as follows:
(1) for conduct in connection with a matter pending before a tribunal, the rules of the jurisdiction in which the tribunal sits, unless the rules of the tribunal provide otherwise; and
(2) for any other conduct, the rules of the jurisdiction in which the lawyer's conduct occurred, or, if the predominant effect of the conduct is in a different jurisdiction, the rules of that jurisdiction shall be applied to the conduct.
