In the United States Supreme Court case of The United States v. George Fleming's Heirs, the court was asked to decide whether a patent issued by Congress for land in Kentucky could be revoked due to an alleged fraud committed by its original owner. The appellant argued that since the patent had been granted and accepted without any knowledge of fraud, it should remain valid despite evidence of fraudulent activity during its acquisition. However, the respondents argued that because there was clear evidence of fraud on behalf of George Fleming when he acquired his title from Virginia in 1783, they were entitled to have their claim recognized as valid under common law principles. After considering both sides' arguments and examining relevant statutes and precedents related to patents issued by Congress, the court ultimately ruled in favor of revoking Mr. Fleming's patent due to his fraudulent behavior when obtaining it from Virginia over fifty years prior.

In the United States v. George Fleming's Heirs, the Supreme Court was tasked with determining whether a certain tract of land in Kentucky belonged to the United States or to heirs of George Fleming. The majority opinion held that it belonged to the United States because they had acquired title from Virginia prior to Kentucky becoming a state and therefore had superior rights over any claim by individuals who may have obtained title after that time. However, Justice McLean dissented on this ruling as he believed that there were sufficient facts presented which showed that Mr. Fleming did indeed possess valid legal title at the time when Kentucky became a state and thus his heirs should be entitled to ownership of said property regardless of any prior claims made by Virginia or subsequently acquired by the US government. Furthermore, Justice McLean argued that if such an interpretation was not adopted then it would lead to unjust results whereby private citizens could be deprived of their property without due process simply because another party claimed superior rights based upon earlier possession even though those claims lacked validity under existing law.
