In the case of Wilson v. City of Port Lavaca et al., 1967, the U.S Supreme Court ruled in favor of a black family who had been denied access to a public park due to their race. The city council had leased out the park to a private organization with an agreement that it would only be used by white people, thereby circumventing laws against racial segregation in public places. However, this was challenged by Mr. and Mrs. Wilson on behalf of their minor children who were barred from using the facilities because they were African American. The court held that such leasing arrangements constituted state action and thus fell under Fourteenth Amendment scrutiny which prohibits states from denying any person within its jurisdiction equal protection under law - including discrimination based on race or color in relation to use of public facilities like parks or beaches. This decision reaffirmed previous rulings stating that municipalities cannot evade constitutional obligations by delegating authority over public resources to private entities while maintaining control over those resources indirectly.

In the dissenting opinion for Wilson v. City of Port Lavaca, it was argued that the majority's decision to uphold a city ordinance requiring mobile home owners to obtain permits before moving their homes into or within the city limits violated constitutional rights. The dissenting justices believed that this ordinance unfairly targeted and discriminated against low-income individuals who relied on mobile homes as affordable housing options. They also expressed concern about how such an ordinance could be used by cities to effectively ban certain types of housing they deemed undesirable, thus limiting citizens' freedom of choice in where and how they live. Furthermore, they felt that there was insufficient evidence presented at trial proving any legitimate public interest served by this regulation which would justify its infringement upon these fundamental rights.
