The Impossibility Defense
Your house building company (Builder) is halfway done with the building of a large house when during a thunderstorm, lighting strikes the house, catching it on fire and destroying it. The Builder does everything he can to rebuild the house as fast as possible but he still ends up being 4 months late in finishing the house. Builder’s contract had a serious penalty for each day the job was delayed in being completed. Builder contests the penalty on the basis of the Impossibility Defense.
