Contracts can be declared void if the conditions of the contract become impossible (aka the doctrine of frustration). However, the doctrine cannot be invoked just because one side is going to lose a lot of money on the deal. Maple Farms learned this the hard way in the case of Maple Farms Inc. v. City School Dist. (76 Misc.2d 1080, 352 N.Y.S.2d 784 (N.Y.Sup. 1974)). In that case, Maple Farms supplied milk to a local school district for a set price (a fixed price contract). Market factors in 1973 drove the price of milk too high and it became impractical for Maple to sell the milk without a taking a huge loss. They sued for a declaratory judgment that performance had become impractical The Court dismissed the claim and held Maple responsible for selling the milk.
