Rule 3.4 Fairness to Opposing Party and Counsel

(a) A lawyer shall not unlawfully obstruct another party’s access to evidence or unlawfully alter, destroy, or conceal a document or other material having potential evidentiary value, nor shall a lawyer counsel or assist another person to do any of these acts.

(b) A lawyer shall not falsify evidence, counsel or assist a witness to testify falsely, or offer an inducement to a witness that is prohibited by law.

(c) A lawyer shall not knowingly violate or disobey an order of a tribunal or an obligation under the rules of a tribunal, except for an open refusal based on an assertion that the order is invalid or that no valid obligation exists.

(d) A lawyer shall not make a frivolous discovery request or fail to make reasonably diligent effort to comply with a legally proper discovery request by an opposing party.

(e) A lawyer shall not in trial allude to any matter that the lawyer does not reasonably believe is relevant or that will not be supported by admissible evidence. A lawyer shall not assert personal knowledge of facts in issue except when testifying as a witness, nor state a personal opinion as to the justness of a cause, the credibility of a witness, the culpability of a civil litigant, or the guilt or innocence of an accused.

(f) A lawyer shall not request that a person other than a client refrain from voluntarily giving relevant information to another party unless the person is a relative or an employee or other agent of a client and the lawyer reasonably believes that the person’s interests will not be adversely affected by refraining from giving the information.
