Leonard purchased an unconstructed condominium in a large development. The contract stated that delivery of the completed condo was to be on a date set by the developer before February 1, 2010. Construction proceeded on schedule except on April 25, 2009, the whole development burned to the ground. After spending some time looking for the cause of the fire, the developer started the process of rebuilding in October 2009. It looks like the condo will be delivered about a year later than originally anticipated. Is Leonard bound by the contract under these circumstances? Does it matter if the fire was caused by the developer's negligence?
