Five years after prosecutorial misconduct spoiled the trial of the late Alaska senator Ted Stevens, his legal team won an award Thursday night as “constitutional champions” for exposing wrongdoing at the U.S. Department of Justice.

The Constitution Project, a bipartisan reform group, honored Brendan Sullivan Jr., Robert Cary and other lawyers from Williams & Connolly for insisting that prosecutors in the Stevens corruption trial “fulfill their constitutional obligation to disclose exculpatory evidence.”
