In Randolph et al. v. Barbour et al., the Supreme Court addressed a dispute between two parties over an 1817 contract concerning land in Kentucky and Virginia. The plaintiffs, Randolph et al., argued that they had been wrongfully deprived of their rights under the contract by defendants Barbour et al., who sought to have it declared void due to its alleged illegality under state law. The Supreme Court held that although there was some evidence suggesting that the contract may have violated state law, this did not necessarily render it invalid; rather, such matters should be left for resolution by state courts as opposed to federal courts like the Supreme Court itself. Furthermore, since no proof existed showing any fraud or mistake on either party's part when entering into the agreement, both sides were bound by its terms and thus entitled to enforce them accordingly in court if necessary. Ultimately, therefore, while recognizing potential issues with respect to legality of contracts at issue within states' jurisdiction alone - which could potentially lead to disputes among private citizens -the ruling ultimately reaffirmed basic principles of contractual obligation applicable across all jurisdictions regardless of local laws or regulations governing such agreements

In Randolph et al. v. Barbour et al., Chief Justice John Marshall wrote a dissenting opinion in which he argued that the Court should not have dismissed the case on procedural grounds, but instead should have decided it on its merits. He stated that Congress had passed an act to enable citizens of Virginia to sue for damages caused by state officials and that this was sufficient authority for the suit brought by Randolph and others against Barbour and other state officers. Furthermore, he noted that although there were some technical errors in how they filed their complaint, these did not affect their right to bring suit or render them liable for costs if unsuccessful; thus, those issues could be addressed after deciding whether they had a valid claim against the defendants. Finally, Marshall concluded his dissent with an argument about why federal courts should decide cases involving constitutional questions even when such decisions may conflict with state laws: because without doing so “the Constitution itself would become a dead letter” as states are free to ignore it whenever convenient or advantageous
