Some cases of comparative negligence in contract law have found fault by the injured party in breaching a duty contemplated by the agreement. Other cases, however, have gone beyond that. They have found the injured party at fault because of unreasonable actions, despite the absence of a clear agreement.In contractual duty cases, the rationale of comparative negligence is based on the expression of the agreement of both parties. However, that analysis falters in non-contractual duty cases. Why should an injured party be required to behave reasonably in the absence of a contractual obligation? The presence of an agreement or contract is not enough to explain all cases of comparative negligence.
