New York and Colorado Mining Syndicate and Company v. Frase was a Supreme Court case that was decided in 1891. The case involved a dispute between the New York and Colorado Mining Syndicate and Company and the defendant, Frase. The plaintiff, New York and Colorado Mining Syndicate and Company, had purchased a mining claim in Colorado from Frase. The plaintiff alleged that Frase had misrepresented the quality of the claim and that they had been damaged as a result. The Supreme Court held that the plaintiff had failed to prove that Frase had made any misrepresentations and that the plaintiff had failed to prove that they had been damaged as a result. The Court also held that the plaintiff had failed to prove that Frase had acted in bad faith. As a result, the Supreme Court dismissed the case and ruled in favor of the defendant.

In the dissenting opinion of New York and Colorado Mining Syndicate and Company v. Frase, Justice Field argued that the majority’s decision was in error because it failed to consider certain facts regarding the case. Specifically, he noted that while a contract between two parties may be valid under state law, if one party has not performed their obligations as outlined in said contract then they cannot seek damages for breach of such an agreement. He further stated that even though there had been some performance on behalf of both parties prior to any alleged breach by either side, this did not necessarily mean that all conditions had been met or fulfilled according to the terms laid out within said contract. As such, he concluded that since neither party could prove full compliance with all contractual requirements at issue here, no action should have been taken against either side for breach thereof.
