Palese bought five lottery tickets. He used a “play slip” to select his numbers, then filled them in on the grid. He put his tickets in his pocket. At home, he did the laundry. Several days later, he heard someone had won the lottery but had not claimed the prize. He searched for his ticket, then realized it had been washed and destroyed. His play slip had not been in his pocket, and he realized from the slip that he had won. He wrote the lottery explaining his dilemma. The lottery said he would have to wait a year, and if no one else claimed the prize, it would consider whether the play slip would entitle him to the prize. Later, when he contacted the lottery, it said that he would have to have the ticket in order to claim the prize. Palese sued the lottery claiming it had been unjustly enriched. Should Palese be awarded the prize? Why?
