v. Kraemer, 334 U.S. 1 (1948)
nThe
federal guaranty of due process extends to state action through its
judicial as well as through its legislative, executive or administrative
branch of government. . . . We hold that, in granting
judicial enforcement of the restrictive agreements in these
cases, the States have denied petitioners the equal protection
of the laws, and that, therefore, the action of the state
courts cannot stand.
