(CNN) -- A Delaware man who spent more than 20 years on death row saw his murder conviction and death sentence reversed by the state Supreme Court Monday, according to court documents. Jermaine Wright, 41, was sentenced to death for the 1991 murder of liquor store clerk Phillip Seifert. State Supreme Court justices ruled that prosecutors withheld critical and potentially exculpatory information during the 1992 trial that violated his right to due process, entitling Wright to a retrial. The suppression of such information "creates a reasonable probability that the verdict would have been different if the exculpatory and impeachment evidence had been disclosed," wrote Justice Henry Ridgely in the decision. "Accordingly, we must reverse Wright's conviction and death sentence and remand for a new trial."
