The botched corruption prosecution of the late U.S. Sen. Ted Stevens was one of the Justice Department’s darkest moments. The case failed because it emerged that prosecutors had played fast and loose with the rules — defense attorney Brendan Sullivan, whose other clients have included former Cendant Corp. Chairman Walter Forbes and Broadcom Corp. co-founder Henry Nicholas III, called it the worst case of prosecutorial misconduct he’s seen in 42 years in practice.

Sullivan and partner Robert Cary are campaigning to crack down on prosecutors, and have found support in the federal judiciary — a pending rule change would mandate disclosure of exculpatory information.

“We are going to continue to fight in the name of Sen. Ted Stevens to bring about change because of what was done to that gentleman,” Sullivan said.

The case will be “an opportunity lost if we don’t have meaningful, permanent reform,” Cary said.
