In Crespin v. United States (1897), the U.S. Supreme Court examined a case involving land grants in New Mexico, which were given by Spain and later recognized by the Treaty of Guadalupe Hidalgo after the Mexican-American War. The plaintiff, Crespin, claimed that he was entitled to certain lands based on an 1823 grant from Spanish authorities to his ancestors. However, this claim was rejected by both lower courts and eventually reached the Supreme Court. The main issue before the court was whether or not Crespin could prove that his family had maintained continuous possession of these lands since they were granted in 1823 - a requirement under Spanish law for maintaining ownership rights over such grants. The Supreme Court ruled against Crespin because he failed to provide sufficient evidence proving continuous possession of these lands since their original grant date. This ruling upheld previous decisions made by lower courts rejecting Crespin's claims due to lack of proof regarding uninterrupted control over said property.

The dissenting opinion in the Crespin v. United States case argued that the majority's decision to uphold Crespin's conviction was flawed due to a lack of evidence proving his guilt beyond reasonable doubt. The dissenting justices believed that there were significant inconsistencies and contradictions within the testimonies provided by government witnesses, which raised questions about their credibility. They also pointed out that no physical evidence directly linked Crespin to the crime he was accused of committing, making it difficult for them to confidently affirm his guilt. Furthermore, they expressed concerns over potential bias within the jury selection process as well as procedural errors during trial proceedings which may have unfairly influenced its outcome against Crespin. Therefore, they felt an acquittal or at least a retrial would be more appropriate under these circumstances.
