In the United States v. Shotwell Manufacturing Co. et al., 1957, the Supreme Court ruled on a case involving tax evasion and bribery of federal officials. The defendants, Shotwell Manufacturing Company and its officers, were accused of evading taxes by underreporting income from black-market sales during World War II. They claimed that they had made an offer to disclose this information to Internal Revenue Service (IRS) agents in exchange for immunity but were rejected because they refused to bribe the agents as requested. The court held that if such allegations are true, it would constitute a violation of due process rights under the Fifth Amendment since evidence obtained through such means is tainted and should be excluded from trial proceedings - known as "the fruit of the poisonous tree" doctrine. However, in this particular case, there was no clear proof that any alleged bribery attempt influenced or led directly to obtaining incriminating evidence against them; thus their convictions stood.

The dissenting opinion in the United States v. Shotwell Manufacturing Co. case argued that the majority's decision to remand the case for a new trial was unnecessary and unjustified, as there was no evidence of misconduct on behalf of government officials or any violation of defendants' rights during their initial trial. The dissenters believed that even if some tax evasion had been committed by Shotwell Manufacturing Company, it did not warrant a retrial because such actions were not directly related to the charges against them for fraudulently obtaining war contracts from the government. They also disagreed with the majority's interpretation of Rule 33, which allows for new trials based on newly discovered evidence; they felt this rule should only apply when such evidence could have affected jury verdicts at original trials rather than being used as an excuse to retry cases whenever potentially exculpatory information comes forward after convictions are already secured.
