The frustration of purpose doctrine arose from the so-called coronation cases in England.Numerous parties had contracted for rooms along the parade route for the king's coronation,but the king became ill and the coronation was canceled.The courts held that the parties' duties under the room contracts should be discharged,and that any payments made in advance should be returned because the essential purposes of the contracts could no longer be fulfilled,through no fault of any of the parties.
