In the 1927 case of Casey v. United States, the Supreme Court ruled on a matter related to prohibition laws and their enforcement. The defendant, Mr. Casey, was convicted for possessing liquor with intent to sell in violation of the National Prohibition Act after officers found alcohol in his home during an illegal search without a warrant. On appeal, he argued that this evidence should not have been admitted due to its unlawful acquisition by law enforcement officials. The Supreme Court upheld his conviction despite acknowledging that the search had indeed violated his Fourth Amendment rights against unreasonable searches and seizures. The court reasoned that while such violations could be grounds for action against offending officers or as defense in proceedings for trespassing or false imprisonment brought by defendants like Mr.Casey himself; they did not necessarily exclude unlawfully seized evidence from being used at trial. This decision essentially established what came to be known as "the silver platter doctrine," which allowed federal courts to admit evidence obtained illegally by state police until it was overruled later in 1960 (Elkins v.United States).

In the dissenting opinion for Casey v. United States, 1927, it was argued that the majority's interpretation of the National Prohibition Act was too broad and overreaching. The dissenting justices believed that Congress did not intend to criminalize all possession of alcohol but rather only those instances where intent to sell could be proven. They contended that personal use or consumption should not fall under this law as it would infrally on individual liberties without sufficient justification in terms of public safety or welfare. Furthermore, they expressed concerns about potential abuses and misapplications of such a wide-ranging law by enforcement authorities. In their view, interpreting the act in this manner set a dangerous precedent for future legislation and judicial decisions regarding individual rights versus government control.
