Associated Press reports the state's district attorneys will move to dismiss the cases because disgraced, convicted state chemist Annie Dookhan was involved in testing the alleged drugs in the cases.
The ACLU says this will be the largest mass dismissal of cases in US history.
The Dig reminds us the state is still processing cases related to a second chemist-gone-bad, Sonja Farak, out in Amherst.
The bulk of the Dookhan convictions - 15,570 - are in Suffolk County, where the District Attorney's office reports it is not filing for dismissal of cases involving 117 defendants. In a statement, DA Dan Conley said:
The 117 defendants identified in these cases account for more than 1,700 convictions for violent crimes or weapons violations, and have amassed more than 2,800 convictions in total.
