Tony, a hateful, disgruntled, business law teacher notices that a student, Peter, who is past the age of majority, has a nice motorcycle that is for sale. Peter has struggled through school, is in his last semester, and needs to pass business law in order to graduate. Tony tells Peter that he would like to see Peter pass and, in the next sentence, says that he wants to buy the motorcycle for $100, a price far below the value of the motorcycle. Peter asks if Tony is serious about the price, and Tony replies, "I have the power here! Take it or leave it!" Tony proceeds to draw up a contract for the sale of the motorcycle for $100 which Peter signs. Peter does some research and finds that Tony has had several arrests for driving under the influence in a nearby town. As an act of revenge, Peter tells Tony that unless Tony sells Peter his new Mustang convertible for $50, he is publishing the facts about the arrests in the school newspaper. Tony reluctantly agreed to the deal. Which of the following is true if Tony seeks to rescind the contract for the sale of the Mustang?
A. Tony may rescind the contract on grounds of duress.
B. Tony may rescind the contract on grounds of misappropriation of name or likeness.
C. Tony may rescind the contract on grounds of fraud.
D. Tony may not rescind the contract because truth is involved.
E. Tony may rescind the contract on grounds of defamation.

For contracts to be considered enforceable, a key factor is that the parties involved must have entered into the agreement of their own accord and free will. Therefore Duress, which denies a person of that free will, becomes a reason why a contract can be voided.

Tony sold Peter the Mustang convertible because Peter had threatened to release details that Tony would rather were kept private so Tony capitulated and sold the Mustang. Had Peter not threatened him, Tony would not have sold the car. This shows that Tony only sold the car under duress and as such can void the contract.
