Paul owns a large vacant lot in a small town. Last year, he subdivided his lot and sold two plots to Marie Renard and Jean Lafouine. When he learned of the sale, the mayor of the municipality was furious and promised to pass a municipal by-law to prevent the development of a new neighborhood in this area (better known in the municipality as By-law 13) . Aline contacts Paul. She wants to buy land from him for $100,000. Their agreement dated March 3, however, provides that the sale will take place only if the municipality does not ratify by September 30, its draft by-law aimed at limiting real estate development (By-law 13). On June 4, the mayor dies. A new mayor is elected for a 4-year term on August 15, his only electoral promise was to bury the draft by-law 13. On September 2, during the first municipal assembly, the new mayor confirms that the municipality will not go move forward with the contested project to prevent real estate development in the municipality. The next municipal assembly will only take place on October 8. It is September 4, does Aline have an obligation to pay Paul?
