Jacob Le Roy brought a case against William Beard to the Supreme Court of the United States. Le Roy argued that he had been wrongfully evicted from his land by Beard, who was claiming ownership over it. The court found in favor of Le Roy and ruled that he should be restored to possession of his property as well as damages for any losses suffered due to being unlawfully removed from it. This decision established an important precedent for future cases involving wrongful eviction and clarified the rights of landowners under U.S law at the time. It also set out guidelines on how courts should handle disputes between two parties when one is attempting to take control over another's land without proper legal authority or justification, such as through force or intimidation tactics. Ultimately, this ruling provided greater protection for individuals' private property rights and ensured they could not be taken away without just cause or due process of law

In Jacob Le Roy v. William Beard, the Supreme Court was asked to decide whether a contract between two parties could be enforced if it had been made in violation of an existing state statute. The majority opinion held that such contracts were not enforceable and thus granted judgment for the defendant. However, Justice McLean dissented from this decision on the grounds that there is no legal principle which states that all contracts made in violation of a law are void and unenforceable. He argued that while some laws may make certain agreements illegal or void ab initio (from their inception), others merely impose penalties upon those who enter into them without invalidating them entirely. Therefore, he concluded, each case must be decided based on its own facts and circumstances rather than by general rules applicable to all cases involving violations of statutes.
