Justice Ketanji Brown Jackson on Monday wrote her first opinion since taking office over the summer, objecting to the Supreme Court’s decision not side with an Ohio death row inmate’s claim.
Chinn's lawyers argued that prosecutors had withheld evidence that a key witness, Marvin Washington, was severely mentally disabled, with an IQ of 48.
Jackson wrote in an opinion dissenting from the court’s decision to reject Chinn’s claim that there was “no dispute” that the state had suppressed evidence that would have undermined Washington’s credibility as a witness.
Under a 1963 Supreme Court ruling called Brady v. Maryland, such conduct can constitute a due process violation.
Jackson, the first Black woman to serve on the Supreme Court, was appointed by President Joe Biden to replace fellow liberal Justice Stephen Breyer, who retired over the summer.
