Under which legal theory or theories might Sun Farms claim that its obligation under the contract has been discharged by operation of law? Discuss fully.
Val’s Foods signs a contract to buy 1,500 pounds of basil from Sun Farms, a small organic herb grower, as long as an independent organization inspects the crop and certifies that it contains no pesticide or herbicide residue. Val’s has a contract with several restaurant chains to supply pesto and intends to use Sun Farms’ basil in the pesto to fulfill these contracts. While Sun Farms is preparing to harvest the basil, an unexpected hailstorm destroys half the crop. Sun Farms attempts to purchase additional basil from other farms, but it is late in the season and the price is twice the normal market price. Sun Farms is too small to absorb this cost and immediately notifies Val’s that it will not fulfill the contract.
