From the N&O:
With his client dead, Hughes said, he immediately thought of revealing Cashwell's secret. But he decided to wait, knowing that the Supreme Court was considering a crucial ruling on an unrelated case in Wake County that explored whether a dead person's confidentiality trumped the search for justice.
In 2003, the Supreme Court said that a judge can force a lawyer to reveal confidential statements from a dead client. The decision helped crack the arsenic poisoning case of Eric Miller, leading to his wife's arrest and conviction.
Bolstered by that decision, Hughes eventually decided he would reveal his dead client's confession. In 2004, Hughes called Rich Rosen, who is known for handling cases for prisoners who insist they are wrongly convicted, and said he had evidence that could help prove Hunt's innocence.
