Frustration and Termination by Notice
The central proposition is that mere hardship or difficulty or increased expense will not form the basis for terminating the contract under general law. Instead the doctrine of frustration is confined to supervening impossibility, (non-culpable and non-elective) incapacitation, or illegality. Another topic treated here is contracts of indefinite duration. These are normally capable of being terminated by one party giving reasonable notice to the other.
