Jamal has been the owner of a car dealership for 10 years. One day, Jamal sold one of his most expensive cars to Abdul. At the time of the sale, Jamal thought Abdul acted in a peculiar manner, but he gave the matter no further thought until four months later when Abdul's court-appointed guardian appeared in Jamal's office, returned the car, and demanded Abdul's money back. The guardian informed Jamal that Abdul had been adjudicated mentally incompetent two months earlier by a prior court.

A. Discuss the rights of the parties in this situation?

B. If Abdul had been adjudicated mentally incompetent before the contract was formed, what would be the legal effect of the contract?
