Calvin consulted a lawyer and asked the two questions below.
Did he have the mental capacity to enter into the contract when he agreed to let Billy sell the penny? What would he have to prove to show a court that he did not have the necessary mental capacity when he authorized Billy to sell the penny?
Did Billy exert undue influence over Calvin to cause Calvin to enter into the contract that allowed Billy to sell the penny?
What do you think? Does Calvin have a case to set aside the contract with Billy on either of these theories?
