Washington, June 30 (RHC)-- The U.S. Supreme Court has rolled back a landmark decision on tribal sovereignty it delivered just two years ago in the historic ruling McGirt v. Oklahoma. 

In a 5-4 vote, justices ruled Wednesday that the state of Oklahoma has concurrent jurisdiction and may prosecute non-Indigenous people when a crime is committed on a reservation and the victim is Native American.

Meanwhile, Ketanji Brown Jackson began her tenure on Thursday as the first Black woman on the U.S. Supreme Court, after Justice Stephen Breyer said Wednesday would be his last full day on the job.  Breyer, who is 83 years old, announced his intention to retire in January.
