In the case of Ohio v. Gallagher, the U.S Supreme Court was asked to consider whether a state could constitutionally impose an excise tax on liquor sales by private clubs to their members. The appellant, a member of such a club in Ohio, argued that this taxation violated his constitutional rights under both the Equal Protection and Due Process Clauses of the Fourteenth Amendment. He contended that it was discriminatory for states to tax private club transactions while exempting similar transactions occurring at other locations like homes or offices from such taxes. The court ruled against Gallagher's arguments stating that there is no fundamental right involved in purchasing liquor nor does any suspect classification exist here which would require strict scrutiny review. Furthermore, they found no violation of equal protection as all similarly situated entities (private clubs) were being treated equally under law with respect to taxation. Additionally, regarding due process claims, it was held that since alcohol regulation falls within police power scope and because this particular tax bore rational relation to legitimate state interest (raising revenue), it did not violate due process clause either.

In the dissenting opinion for Ohio v. Gallagher, it was argued that the majority's decision to uphold a warrantless search of an automobile based on probable cause alone significantly eroded Fourth Amendment protections against unreasonable searches and seizures. The dissenters believed that this ruling effectively eliminated any distinction between searches of homes and vehicles, despite traditionally stronger constitutional safeguards for residences due to their inherent privacy expectations. They contended that such a broad interpretation could lead to potential abuses by law enforcement officials who might exploit this loophole in order to conduct invasive searches without obtaining necessary warrants first. Furthermore, they expressed concern over how this precedent might impact future cases involving similar circumstances, potentially undermining citizens' rights under the Constitution.
