In the 1952 case of Bridges et al. v. United States, Harry Bridges and two other defendants were convicted for perjury under Section 145(b) of the Internal Revenue Code, which makes it a felony to knowingly provide false information in any matter within federal jurisdiction. The charges stemmed from allegations that they had lied about their membership in the Communist Party on naturalization applications and during subsequent investigations by immigration officials. The Supreme Court upheld these convictions with a majority decision, ruling that even though some evidence was circumstantial or hearsay, there was still sufficient proof to support the jury's verdicts beyond reasonable doubt. This case is significant as it affirmed that providing false statements on official documents or proceedings can lead to criminal penalties regardless of whether those lies directly influenced outcomes.

In the dissenting opinion for Bridges et al. v. United States, Justice Black argued that the majority's decision to deport Harry Bridges was based on a misinterpretation of the Smith Act and an overreach of federal power. He contended that there was no evidence proving Bridges had advocated or taught doctrines advocating overthrowing the U.S government by force or violence at any time after his admission into this country in 1920, which is what he would have needed to do under law to be deported as an alien member of Communist Party. Furthermore, he believed it was unconstitutional for Congress to give executive officers broad discretionary powers without providing clear standards for their use; such vague laws could lead to arbitrary enforcement and potential abuse of power. Lastly, Justice Black expressed concern about how this ruling might impact other immigrants who may fear expressing their political beliefs due to possible deportation threats.
