(e) 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

(f) request a person other than a client to refrain from voluntarily giving relevant information to another party unless:

(1) the person is a relative or an employee or other agent of a client; and

(2) the lawyer reasonably believes that the person's interests will not be adversely affected by refraining from giving such information.

Minn. R. Prof'l. Cond. 3.4

Comment

[1] The procedure of the adversary system contemplates that the evidence in a case is to be marshalled competitively by the contending parties. Fair competition in the adversary system is secured by prohibitions against destruction or concealment of evidence, improperly influencing witnesses, obstructive tactics in discovery procedure, and the like.

[2] Documents and other items of evidence are often essential to establish a claim or defense. Subject to evidentiary privileges, the right of an opposing party, including the government, to obtain evidence through discovery or subpoena is an important procedural right. The exercise of that right can be frustrated if relevant material is altered, concealed or destroyed.

[3] With regard to paragraph (b), it is not improper to pay a witness's expenses or to compensate an expert witness on terms permitted by law.

[4] Paragraph (f) permits a lawyer to advise employees of a client to refrain from giving information to another party, for the employees may identify their interests with those of the client. See also Rule 4.2.
