In Wabash and Erie Canal vs. Beers, the Supreme Court considered a case involving an Indiana statute that allowed for the sale of certain canal lands to pay off debts owed by the state-owned company. The plaintiffs argued that this violated their rights under Article I, Section 10 of the U.S. Constitution which prohibits states from passing laws impairing contracts without due process of law or taking private property for public use without just compensation. The Supreme Court held that while Congress had exclusive power over interstate commerce, it did not have exclusive authority over intrastate commerce such as canals within a single state's borders; thus, it was up to each individual state to regulate its own internal affairs in accordance with its own constitution and laws so long as they did not conflict with federal statutes or constitutional provisions applicable on a national level. Furthermore, since there was no evidence presented showing any impairment of contract between parties involved in this particular case nor any taking of private property for public use without just compensation being made by Indiana’s legislature when enacting said statute into law – both requirements necessary before violating Article I - then no violation occurred here either and therefore judgment should be rendered in favor of defendant Beers

In Wabash and Erie Canal vs. Beers, the Supreme Court was asked to decide whether a state could tax property owned by citizens of another state. The majority opinion held that states were not allowed to do so under the Constitution's Commerce Clause, which gives Congress exclusive power over interstate commerce. However, Justice Grier dissented from this decision on two grounds: firstly, he argued that it would be unfair for one state to have more taxing authority than another; secondly, he contended that if Congress had intended such a limitation on taxation powers they would have included it in their legislation or made some other provision for it in the Constitution itself. He concluded by stating his belief that allowing states to impose taxes upon citizens of other states did not violate any constitutional provisions and should therefore be upheld as valid law.
