Thomas Wood, Junior was the claimant of twenty-two packages or pieces of cloth. He brought a case against the United States in which he argued that duties had been illegally imposed on his goods when they were imported from England to New York. The Supreme Court heard this case and ultimately decided in favor of the United States, ruling that Congress had authority to impose such duties under their power to regulate foreign commerce as granted by Article I Section 8 Clause 3 of the Constitution. This decision established an important precedent for future cases involving Congressional powers over foreign trade and imports into America.

In Thomas Wood, Junior v. The United States, the Supreme Court was asked to decide whether a certain shipment of cloth imported from England had been subject to duty under an act of Congress. Justice McLean dissented from the majority opinion and argued that since there was no evidence presented in court as to what kind of cloth it was or how much it weighed, the jury should have been allowed to make their own determination on this matter. He further argued that if they were not able to do so due to lack of information then they should be instructed by the court as per established legal principles regarding such matters. In conclusion, he stated that while he agreed with some aspects of the majority opinion he believed that allowing juries more discretion in these types of cases would lead them towards making better decisions than those made by judges alone without any input from jurors.
