A licensee may not make any effort, direct or indirect, which in any manner is calculated to influence the sound professional judgment of another licensee. It is the right of any licensee, without fear or favor, to give proper advice to those seeking relief against substandard or neglectful veterinary or equine dentistry services, to make a complaint to the Board, or to act as a witness in a Board investigation or a contested hearing. A licensee who makes a complaint against another licensee that is groundless and brought in bad faith, for the purpose of harassment, retaliation, or for any other improper purpose shall be in violation of this rule.
