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. A lawyer shall not counsel or assist another person to do any such act;
- falsify evidence, counsel or assist a witness to testify falsely, or offer an inducement to a witness that is prohibited by law;
- knowingly disobey an obligation under the rules of a tribunal except for an open refusal based on an assertion that no valid obligation exists;
- in pretrial procedure, make a frivolous discovery request or fail to make reasonably diligent effort to comply with a legally proper discovery request by an opposing party;
- in trial, allude to any matter that the lawyer does not reasonably believe is relevant or that will not be supported by admissible evidence, assert personal knowledge of facts in issue except when testifying as a witness, or 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; or
- request a person other than a client to 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 such information.
- In representing a client, a lawyer shall not use means that have no substantial purpose other than to embarrass, delay, or burden a third person, or use methods of obtaining evidence that violate the legal rights of such a person.
- A lawyer who receives a document or electronically stored information relating to the representation of the lawyer's client and knows or reasonably should know that the document or electronically stored information was inadvertently sent shall promptly notify the sender.
. . . . [T]his Rule does not address the legal duties of a lawyer who receives a document that the lawyer knows or reasonably should know may have been wrongfully obtained by the sending person.
