It seems that a serendipitous confluence of unusual events is responsible for the heightened scrutiny that prosecutors who worked on the now-dismissed corruption case of former Alaska Republican Sen. Ted Stevens are receiving. Whatever the reasons, the attention is welcome, especially if it leads to more effective sanctions against prosecutorial misconduct.


Mr. Stevens was convicted last October, just before losing his bid for reelection, on seven counts of lying about some $250,000 in gifts he received, including free renovations on his house in Alaska. Last week, however, Attorney General Eric Holder asked the judge in the case to dismiss the charges because prosecutors had engaged in serious misconduct. An FBI agent had come forward to complain about the prosecutors, and an investigation showed that the prosecutors had withheld information from the defense that could have been exculpatory.


U.S. District Judge Emmet Sullivan not only dismissed the case, he appointed an outside lawyer to investigate the conduct of six members of the prosecution team. The investigation could lead to reprimands, disbarment, even criminal charges.


This situation seems to have depended on some unique circumstances. An FBI agent got angry enough to denounce prosecutors. A new attorney general, determined to put his own stamp on the Justice Department, found a case in which he could show his fairness in the case of a prominent member of the other political party. And a judge who was already upset he had held several people in contempt during the trial found a situation in which he could do more than just grouse to his colleagues.


We hope that this case leads to more widespread reform or at least more effective oversight of a practice that is more common than many would like to admit, for quite human reasons.


Whatever the outcome of the Stevens case investigations, they should shed a spotlight on the issue of prosecutorial misconduct which is especially egregious when it results in freeing a guilty person and deter it to some extent. Other reforms might be considered.


We would suggest that more individual accountability might be appropriate. If the worst that happens is a new trial, prosecutors might consider bending the rules, but if they are subject to personal sanctions firing, disbarment or even criminal charges that would be a powerful deterrent.
