Answer:
If a court finds that the one of Pilgrim's principal purposes in the agreement was the inclusion of an ice-skating pond, the Pilgrim-Celestial contract could be discharged via the doctrine of:
Frustration of Purpose.
Step-by-step explanation:
The doctrine of Frustration of Purpose occurs when there is a change of circumstances that is not the fault of either Pilgrim Industries or Celestial City Resort. Since these two parties did not cause the circumstances that made it legally, physically, or commercially impossible to fulfil the contract, the contract can be discharged by the court based on this doctrine. It is also known as Force Majeure.
