§ 1983, that person could bring suit for monetary damages against the prison guard. Without § 1983, that person would have to seek an injunction by the courts for the due process violation. The problem with such an action by the court is that injunctions, which instruct a party on penalty of contempt to perform or refrain from performing some action, cannot apply to past harm, only future harm. So, essentially the person would have an actionable cause—the constitutional violation—with no adequate remedy. Most § 1983 claims are brought against prison officials by prisoners, but prisoner claims are usually dismissed as being without merit. Claims can be brought by anyone stating a proper cause of action. Circumstances changed in 1961 when the Supreme Court of the United States articulated three purposes that underlie the statute: "1) 'to override certain kinds of state laws'; 2) to provide 'a remedy where state law was inadequate'; and 3) to provide 'a federal remedy where the state remedy, though adequate in theory, was not available in practice.' " A §1983 claim requires according to the United States Supreme Court in Adickes v. S. H. Kress & Co. (1970) two elements for recovery: (1) the plaintiff must prove that the defendant has deprived him of a right secured by the, "constitution and laws," of the US, and (2) the plaintiff must show that the defendant deprived him of this constitutional right 'under color of any statute, ordinance, regulation, custom, or usage, of any State or Territory' (under color of law). Now the statute stands as one of the most powerful authorities with which state and federal courts may protect those whose rights are deprived. Section 1983 of the 1871 Civil Rights Act provides a way individuals can sue to redress when their federally protected rights are violated, like the First Amendment rights and the Due Process Clause and the Equal Protection Clause of the Fourteenth Amendment. Section 1983 can be used to redress violated rights based on the federal Constitution and federal statutes, such as the prohibition of public sector employment discrimination based on race, color, national origin, sex, and religion. In some jurisdictions, § 1983 has been applied directly to private employers when litigants have sued under this act. It can also be applied in virtually all jurisdictions in a more indirect manner to private employers if they are acting under state or federal
