Streets and on 60th, 61st and 62nd Streets between South Park and Cottage Grove Avenues" on September 30, 1927, and they were recorded at the Cook County Register of Deeds on February 1, 1928. They were intended to be valid and in force until January 1, 1948. The Great Depression decreased white demand for the subdivision's properties. A few well-off African Americans convinced some owners to sell properties to them. The most famous case was that of Dr. James L. Hall, who rented a property located at 419 E. 60th St. from the white Issac Kleiman. In 1933, Olive Ida Burke (the wife of Mr. Burke—a future defendant in the famous Hansberry v. Lee case) sued Kleiman in the case now known as Burke v. Kleiman. The circuit court granted an injunction in favor of the plaintiffs, which was upheld on appeal by the Supreme Court of Illinois. The plaintiffs stipulated that as of 1928 more than 95% of the property owners signed the covenant. This stipulation was later proved false—only 54% had actually signed. In 1937, Carl Hansberry purchased a property from James Joseph Burke located at 6140 South Rhodes. Anna M. Lee, and other promoters of the covenants, sued to prevent Hansberry's family from living in the neighborhood. This led to the Hansberry v. Lee, case. Defendants argued that the stipulation made previously in Burke v. Kleiman that more than 95% of the owners had signed the covenant was false and the case should be re-adjudicated. Plaintiffs, while admitting to the fact, contended that the principle of res judicata barred courts from rehearing the old arguments. The Illinois courts ruled in favor of plaintiffs. However the National Association for the Advancement of Colored People decided to represent the buyer in the United States Supreme Court. The case caught the attention of national real estate magazines and African American newspapers. The U. S. Supreme Court eventually reversed that ruling stating the application of res judicata in this case would violate Fourteenth Amendment. The play Raisin in the Sun was inspired by Lorraine Hansberry's time in the neighborhood after her father won the repeal of restrictive covenants. The result of Hansberry v. Lee led to racial succession. White tenants were often evicted to make way for higher-paying African American renters. By 1950, the subdivision was over 99 percent African American. The Hansberry case is a seminal case in civil procedure
