In Dredge et al. v. Forsyth, the Supreme Court of the United States was asked to decide whether a state could impose taxes on goods imported from another state for sale within its own borders. The plaintiffs argued that such taxation violated Article I, Section 10 of the Constitution which prohibits states from imposing duties or imposts on imports without congressional consent. The defendants argued that since Congress had not specifically prohibited this type of taxation in their legislation, it should be allowed under the Tenth Amendment's reservation clause which reserves all powers not delegated to Congress by the Constitution to individual states and citizens respectively. After considering both arguments carefully, Chief Justice Taney delivered an opinion for a unanimous court finding in favor of Dredge et al., ruling that any tax imposed upon goods imported into one state from another is unconstitutional unless authorized by Congress itself as per Article I, Section 10 of the U.S Constitution

In Dredge et al. v. Forsyth, the Supreme Court was asked to decide whether a state court had jurisdiction over an action brought by citizens of one state against citizens of another in which the amount in controversy exceeded $500 and did not involve real estate or title to land. The majority opinion held that such cases were within the exclusive jurisdiction of federal courts, while Justice Field dissented on several grounds. He argued that Congress had no authority under Article III of the Constitution to confer original jurisdiction upon federal courts for this type of case; rather, it should be left up to each individual state's legislature as part of its police power over matters within its borders. Furthermore, he maintained that if Congress could grant such broad powers then it would be able to do so with respect to any matter whatsoever and thus usurp all legislative authority from states altogether - something clearly never intended by our Founding Fathers when they wrote the Constitution. Finally, he noted that even if there were some constitutional basis for granting these powers it would still be unwise policy since allowing individuals from different states access only one forum (federal court) instead two (state and federal) could lead them into unnecessary expense and delay due process rights guaranteed under both constitutions
