In the case of Hudson et al. v. United States in 1926, the Supreme Court ruled on a matter concerning bankruptcy law and its application to stockbrokers. The plaintiffs were trustees for a bankrupt brokerage firm who sought to recover payments made by the firm to certain customers before it declared bankruptcy, arguing that these payments constituted preferences under Section 60b of the Bankruptcy Act because they enabled those customers to receive more than their fair share of the firm's assets. The defendants argued that such transactions were not preferential as they merely reduced or eliminated debts owed by the broker rather than providing any additional benefit beyond what was already owed. The Supreme Court sided with defendants, ruling that such transactions did not constitute preferences under Section 60b unless there was evidence showing intent on part of debtor (broker) or knowledge on part of creditor (customer) about impending insolvency at time transaction took place. This decision clarified an important aspect regarding interpretation and enforcement of preference rules within U.S bankruptcy law.

The dissenting opinion in the case of Hudson et al. v. United States argued that the majority's decision to uphold a conviction based on evidence obtained through an illegal search and seizure was fundamentally flawed. The dissenters believed that this ruling violated the Fourth Amendment rights of the defendants, which protect against unreasonable searches and seizures by law enforcement officials. They contended that allowing such evidence to be used in court would effectively condone unlawful police conduct, undermining citizens' constitutional protections and eroding public trust in law enforcement institutions. Furthermore, they asserted that excluding illegally obtained evidence from trial proceedings does not prevent prosecutors from securing convictions using legally acquired proof; rather it incentivizes them to adhere strictly to lawful investigative methods.
