4. Desiree, a wealthy industrialist with failing eyesight and bad kidneys, enters into a contract with David wherein he agrees to sell one of his eyes and a kidney to her in exchange for a payment of $1,000,000 in cash plus all medical expenses. [The buying and selling of body parts is a crime under both federal and state law.] A week after the successful organ transplant, Desiree informs David that she's changed her mind about the agreed-upon payment because she could have got-ten cheaper prices for the organs on the international organ black market and will only give him $25,000 and pay all medical expenses. David, furious, sues for breach of contract. You are the judge. What result? Explain fully.
