The United States v. John Morrison and Others was a Supreme Court case in which the U.S. government argued that it had exclusive jurisdiction over Indian tribes, including the power to regulate trade with them and punish any violations of its laws by non-Indians on their lands. The appellees, led by John Morrison, were traders who had been charged with violating federal law for trading without a license on Cherokee land in Georgia; they argued that since they were not members of the tribe or subject to its authority, only state law applied to them and thus their actions could not be punished under federal law. In an opinion written by Chief Justice Marshall, the court held that while states did have some limited powers over Indian nations within their borders (such as criminal prosecution), these powers must yield when Congress has acted pursuant to its constitutional authority “to regulate commerce with foreign nations”—which includes Indian tribes—and “to make all needful rules and regulations respecting . . . territories belonging to the United States”—which includes tribal lands occupied by Indians living under federal protection from state interference. Thus, even though Georgia may have claimed sovereignty over Cherokee territory within its borders at this time (a claim later rejected in Worcester v Georgia), Congress still had exclusive jurisdiction here due to its plenary power over such matters involving Native Americans

In the United States vs. John Morrison and Others, Appellees, Chief Justice Marshall delivered a dissenting opinion in which he argued that the Court should have reversed the decision of the Circuit Court. He believed that Congress had not intended to grant exclusive jurisdiction over Indian tribes to state courts when it passed legislation allowing them to sue in federal court for damages caused by non-Indians on their lands. Instead, he argued that Congress had only meant to provide an additional remedy for Indians who were already able to seek redress from state courts if they chose. Furthermore, Marshall contended that even if Congress did intend for exclusive jurisdiction over Indian tribes' claims against non-Indians residing within their boundaries be given exclusively to federal courts, this would still not prevent states from exercising concurrent jurisdiction with respect to other matters concerning those same Indians or disputes between two or more members of a tribe itself. Ultimately, Chief Justice Marshall concluded his dissent by asserting that since there was no clear indication as such from either Congressional intent or Supreme Court precedent regarding this issue at hand - whether states could exercise concurrent jurisdiction with respect tribal matters - then it should be left up each individual state's legislature as well as its own judicial system decide how best handle these cases going forward.
