Rule 408 - Compromise and offers to compromise(a)Prohibited Uses. Evidence of the following is not admissible - on behalf of any party - either to prove or disprove the validity or amount of a disputed claim or to impeach by a prior inconsistent statement or a contradiction: (1) furnishing, promising, or offering - or accepting, promising to accept, or offering to accept - a valuable consideration in compromising or attempting to compromise the claim; and(2) conduct or a statement made during compromise negotiations about the claim. Compromise negotiations encompass mediation.(b)Exceptions. The court may admit this evidence for another purpose, such as proving a witness's bias or prejudice, negating a contention of undue delay, or proving an effort to obstruct a criminal investigation or prosecution. This rule does not require the exclusion of any evidence otherwise discoverable merely because it is presented in the course of compromise negotiations.Adopted January 8, 1985, effective 7/1/1985; amended March 23, 1990, effective 7/1/1990; amended March 26, 2018, effective 7/1/2018.
