In the case of Ganger et al. v. City of Miami, 1958, the appellants were owners and operators of a trailer park in Miami who challenged an ordinance that prohibited them from renting or leasing trailers to African Americans. They argued that this law violated their rights under the Fourteenth Amendment's Equal Protection Clause as it discriminated based on race. The Supreme Court ruled against them stating that since they had not shown any harm caused by this ordinance to themselves personally (as opposed to potential renters), they lacked standing - legal capacity - to challenge its constitutionality. This decision emphasized the principle that one must demonstrate personal injury or threat thereof due to a statute before challenging its validity.

In the dissenting opinion for Ganger et al. v. City of Miami, Justice Hugo Black argued that the majority's decision was a violation of the First Amendment rights to freedom of speech and assembly. He contended that peaceful picketing is a form of expression protected by these constitutional guarantees, regardless if it involves labor disputes or not. Furthermore, he criticized the majority for allowing local authorities to suppress this fundamental right based on their own discretion without any clear standards or guidelines in place. According to him, such an approach could lead to arbitrary and discriminatory enforcement against certain groups or individuals depending on their views or affiliations which goes against democratic principles and values enshrined in the Constitution.
