In the case of Allenberg Cotton Co., Inc. v. Pittman, 1974, the U.S Supreme Court dealt with a dispute over cotton futures contracts between Allenberg Cotton Company and farmer W.E. Pittman. The court had to decide whether federal law preempted state laws that allowed farmers to avoid their obligations under such contracts if they were not licensed commodity merchants as required by Mississippi law at that time. The Supreme Court ruled in favor of Allenberg, holding that federal commodities laws did indeed preempt state licensing requirements for those engaged in interstate commerce involving commodities futures trading. This decision was based on the Supremacy Clause of the United States Constitution which establishes federal law as supreme over conflicting state laws when it comes to regulating interstate commerce. This ruling clarified that individual states cannot impose additional restrictions or requirements on parties involved in federally regulated activities like commodity futures trading beyond what is stipulated by federal legislation.

In the dissenting opinion for Allenberg Cotton Co., Inc. v. Pittman, the justice argued that there was a fundamental misunderstanding of the nature and purpose of futures contracts in cotton trading. The majority's decision to uphold an award based on "lost profits" from a repudiated contract failed to recognize that such contracts are primarily used as hedging tools against price fluctuations rather than speculative investments for profit-making. The dissent further contended that it is impossible to accurately calculate lost profits due to the inherent uncertainty and volatility in commodity markets, making any damage awards purely conjectural or speculative at best. This view held by the minority suggested that damages should be limited only to out-of-pocket losses directly resulting from breach of contract, not hypothetical future gains.
