Whether a private business may be liable under § 1983 for jointly participating with police in racial discrimination or a false arrest.
Holding
Yes. A private party acts under color of state law when it is a willful participant in joint activity with state officials.
Reasoning
Section 1983 requires a deprivation of a federal right and action under color of state law. The Equal Protection Clause forbids a State from discriminating based on a person’s race or the race of her companions, and it also forbids state action that compels or encourages segregation.
If a Kress employee and a Hattiesburg police officer reached an understanding to deny Adickes service or to have her arrested because she was a white person with Black companions, the officer’s involvement would supply the required state action. The private employee and Kress could then be liable because private persons who willfully join state officials in prohibited conduct act under color of law.
