An attempt to contract for an illegal purpose—to commit a murder or other crime or to facilitate an illegal objective (a promissory note for the purchase of illegal drugs)—is unenforceable and does not create a contract. A purported contract that is found to be for an illegal purpose is void and treated as if it never existed.
In Minnesota, as in all states, a contract that is created for an illegal purpose is considered void and unenforceable. This means that if a contract's objective is to commit a crime, such as murder, or to facilitate an illegal activity, such as the purchase of illegal drugs, the law treats the contract as if it never existed. Minnesota courts will not enforce any agreement that requires the performance of an act that violates the law or is against public policy. Therefore, any agreement to perform an illegal act is not a valid contract and has no legal effect. This principle is rooted in the public policy consideration that the law should not be used to promote or condone illegal activities.
