Judge Ketanji Brown Jackson has issued her first Supreme Court opinion in the case of death row inmate Davel Chinn.

According to the Associated Press, Chinn’s lawyers argued that the state suppressed evidence that might have changed the outcome of his trial. Chinn was convicted and sentenced to death for murder in 1989. The main argument from the lawyers was that the state’s primary witness, Marvin Washington, was a 15-year-old with an intellectual disability; therefore, he was not a reliable witness.

The Ohio Public Defender's Office told the Supreme Court, "Without Marvin Washington, that state's evidence was not strong enough to sustain confidence in either Chinn's conviction or death sentenced.”

The high court refused to hear the case. However, Jackson dissented in a two-page opinion with Justice Sonia Sotomayor. Jackson wrote that "because Chinn's life is on the line, and given the substantial likelihood that the suppressed record would have changed the outcome at trial based on the Ohio courts' own representations," she would have ordered more proceedings.
