The Goldberg Conservatory, a music school, ran a notice in several newspapers to announce that it had decided to have a new organ built and installed on its premises. The notice also asked for donations to help fund the project. John Sebastien, a local businessman and patron of the arts, responded to the notice by immediately promising the Conservatory that he would donate $100 000. He explained that a cheque would be sent within a month, after he had made suitable arrangements with his accountant. Before he was able to send a cheque, however, Sebastien's finances suffered a severe setback as a result of several failed business ventures. He therefore informed the Conservatory that, with regret, he would not be able to make a donation after all. The Conservatory insists that he no longer has a choice in the matter. While admitting that it had planned to acquire the organ in any event, it says that it would be unfair if it were to be deprived of the money that Sebastien had promised. It also says that Sebastien is legally obligated to fulfill his promise. Is Sebastien's promise enforceable?
