In Rodiek v. United States (1941), the petitioner, a German national and U.S. resident, was arrested in 1939 under an arrest warrant issued by the Secretary of State for his alleged affiliation with Nazi Germany during World War II. The petitioner challenged his detention arguing that he had not been given a fair hearing to determine whether or not he was dangerous to public safety before being detained. However, the Supreme Court ruled against him stating that due process does not require a pre-detention hearing if there is reasonable cause for arrest based on evidence provided by executive authorities such as FBI reports or other credible sources of information about potential threats to national security.

In the dissenting opinion for Rodiek v. United States, Justice Frank Murphy argued that the majority's decision to uphold a warrantless search and seizure was in violation of Fourth Amendment rights. He contended that there were no exigent circumstances justifying such an intrusion without a warrant, as required by law. The fact that Mr. Rodiek was about to board a ship did not constitute sufficient grounds for bypassing constitutional protections against unreasonable searches and seizures according to him. Furthermore, he disagreed with the majority's view on what constituted 'reasonable' suspicion necessary for conducting such searches; mere presence at a location where illegal activity is suspected should not be enough basis for invasive action by law enforcement officers without concrete evidence or probable cause linking an individual directly to criminal activities.
