The U.S. Supreme Court rules in Shelley v. Kraemer that covenants prohibiting the sale of real estate to blacks and other minorities are legally unenforceable.

The Supreme Court of the United States (SCOTUS) is the highest court in the federal judiciary of the United States. It has ultimate appellate jurisdiction over all U.S. federal court cases, and over state court cases that turn on questions of U.S. constitutional or federal law. It also has original jurisdiction over a narrow range of cases, specifically "all Cases affecting Ambassadors, other public Ministers and Consuls, and those in which a State shall be Party." In 1803, the Court asserted itself the power of judicial review, the ability to invalidate a statute for violating a provision of the Constitution via the landmark case Marbury v. Madison. It is also able to strike down presidential directives for violating either the Constitution or statutory law.

Shelley v. Kraemer, 334 U.S. 1 (1948), is a landmark United States Supreme Court case that held that racially restrictive housing covenants cannot legally be enforced.

Real estate is a property consisting of land and the buildings on it, along with its natural resources such as growing crops, minerals or water, and wild animals; immovable property of this nature; an interest vested in this (also) an item of real property, buildings or housing in general. In terms of law, real relates to land property and is different from personal property, while estate means the "interest" a person has in that land property.
