OKLAHOMA CITY (AP) The Oklahoma Supreme Court on Wednesday dismissed a lawsuit of the last two survivors of the 1921 Tulsa Race Massacre, dampening the hope of advocates for racial justice that the government would make amends for one of the worst single acts of violence against Black people in U.S. history.

The nine-member court upheld the decision made by a district court judge in Tulsa last year , ruling that the plaintiffs grievances, although legitimate, did not fall within the scope of the states public nuisance statute.

We further hold that the plaintiffs allegations do not sufficiently support a claim for unjust enrichment, the court wrote in its decision.

Messages left Wednesday with a spokesperson for the City of Tulsa and the survivors attorney, Damario Solomon-Simmons, were not immediately returned.

The suit was an attempt to force the city of Tulsa and others to make recompense for the destruction by a white mob of the once-thriving Black district known as Greenwood. In 1921 on May 31 and June 1 the white mob, including some people hastily deputized by authorities, looted and burned the district, which was referred to as Black Wall Street.

As many as 300 Black Tulsans were killed, and thousands of survivors were forced for a time into internment camps overseen by the National Guard. Burned bricks and a fragment of a church basement are about all that survive today of the more than 30-block historically Black district.

The two survivors of the attack, Lessie Benningfield Randle and Viola Fletcher, who are both now over 100 years old, sued in 2020 with the hope of seeing what their attorney called justice in their lifetime. A third plaintiff, Hughes Van Ellis , died last year at age 102.

The lawsuit was brought under Oklahomas public nuisance law, arguing that the actions of the white mob continue to affect the city today. It contended that Tulsas long history of racial division and tension stemmed from the massacre.

The city and insurance companies never compensated victims for their losses, and the massacre ultimately resulted in racial and economic disparities that still exist today, the lawsuit argued. It sought a detailed accounting of the property and wealth lost or stolen in the massacre, the construction of a hospital in north Tulsa and the creation of a victims compensation fund, among other things.
