The Collector v. Wilmot was a case heard by the United States Supreme Court in 1821. The dispute centered around whether or not the federal government had the power to impose taxes on private property, specifically land owned by Wilmot. At issue was whether Congress had exceeded its authority under Article I of the Constitution when it passed an act authorizing such taxation without first obtaining consent from state legislatures as required by law at that time. In a 5-4 decision, Chief Justice John Marshall wrote for the majority opinion that Congress did indeed have this power and could tax private property without prior approval from state legislatures. This ruling established precedent for future cases involving similar issues and set forth important principles regarding congressional powers over taxation and other matters related to public policy making.

In The Collector v. Wilmot, the Supreme Court was asked to decide whether a federal tax on land sales violated the Constitution. Chief Justice John Marshall wrote for the majority that Congress had no authority to impose such a tax and it was therefore unconstitutional. However, Justice Joseph Story dissented from this opinion and argued that Congress did have constitutional authority to impose taxes in order to raise revenue for public purposes. He reasoned that since there is no express prohibition against taxing land sales in the Constitution, then it must be assumed that Congress has implied power over taxation of these transactions as part of its general powers granted by Article I Section 8 Clause 1 (the Taxing and Spending Clause). Furthermore, he noted how other forms of property were taxed without any objection or challenge so why should real estate be treated differently? In conclusion, Justice Story believed that if Congress chose not to exercise their right under this clause then they would be abdicating their responsibility as representatives of all citizens who are affected by taxation policies.
