Answer: His argument would be “Discharge by Frustration”
Explanation: There are basically four ways by which a contract can be discharged which includes;
Performance
Agreement
Repudiation and
Frustration
When a contract becomes impracticable from either or both parties to the agreement then it would have to be discharged. In this instance, it is not by agreement, there was no deliberate breach of contractual agreement, and neither is it because the terms of the contract have been fulfilled, but rather because some current unforeseen circumstances have made it impossible for the terms to be fulfilled.
There was an unforeseen event that prevented Ron from continuing with the contractual relationship with his clients, namely the relocation of the landfill to a farther distance. This is beyond his control and continuing with that arrangement would turn his expected profits into losses.
In order not to suffer avoidable losses and possible bankruptcy, Ron has the option of petitioning to be discharged from the contract on the basis of frustration of his efforts.
