In her majority opinion, Justice Ruth Bader Ginsburg directly rebuked the Texas prosecutors for concealing facts they had a legal obligation to disclose and for permitting the state's witnesses to testify untruthfully. Just as forcefully, if implicitly, the majority also rebuked the federal appeals court that in rejecting Mr. Banks's appeal in August 2002 blamed him for having failed earlier to uncover the evidence that the state had withheld.
