United States v. Hudson

Background

A private trader bought and sold certain silver futures in May 1934 and made a profit of $8,621.96 after expenses. He paid a 50% tax under the Silver Purchase Act of June 19, 1934, sought a refund, and sued in the Court of Claims after the refund was denied. The Court of Claims held the retroactive part of the tax invalid as applied to his sales, and the case was then reviewed by the Supreme Court.

Reasoning

The key question was whether applying the tax to sales made between May 15 and June 19, 1934, violated the Constitution’s due process requirement. The Court explained the statute taxed only profits (not all transfers), treating it as a special income tax measured by profit. The opinion relied on earlier decisions that have allowed short retroactive income taxes and found the 35-day retroactive period reasonable given active legislative efforts and a Presidential recommendation urging such a tax. For these reasons the Court reversed the Court of Claims.

Real world impact

The ruling means people who realized profits from silver transfers during May 15–June 19, 1934, can be required to pay the 50% tax. It affirms the established practice that Congress may, in limited circumstances, tax profits retroactively for short periods. The decision resolves this refund claim against the trader and permits the Government to collect the tax as provided by the statute.
