Pileggi owed Young money. Young threatened to bring suit against Pileggi for the amount due. Pileggi feared the embarrassment of being sued and the possibility that he might be thrown into bankruptcy. To avoid being sued, Pileggi executed a promissory note to pay Young the amount due. He later asserted that the note was not binding because he had executed it under duress. Is this defense valid? [Young v Pileggi, 455 A2d 1228 (Pa Super)]
