§ 31-6-14 NMSA 1978

A lawyer or lawyers who are associated in practice shall not continue multiple representation of clients in a grand jury proceeding if the exercise of the lawyer's independent professional judgment on behalf of one of the clients will be or is likely to be adversely affected by his representation of another client. If the court determines that this principle is violated, it may order separate representation of witnesses, giving appropriate weight to an individual's right to counsel of his own choosing.
