BOSTON (Reuters) - Massachusetts' top court will consider arguments Thursday on how to handle tens of thousands of drug convictions that were potentially tainted by a rogue crime lab scientist, in a case that could have national implications.
The American Civil Liberties Union and law firm Foley Hoag will argue at the Massachusetts Supreme Judicial Court for measures to speed up reviews of the cases, and limit the powers of prosecutors to oppose them.
"People who have suffered ... are being scared away from challenging their wrongful convictions by the threat of even harsher punishments," said Foley Hoag partner Daniel Marx in a statement before the hearing.
Former crime lab scientist Annie Dookhan pled guilty in 2013 to tampering with evidence at the now-closed Hinton State Laboratory Institute in Boston, where she worked from 2002 to 2011. She is serving a three-to-five year jail sentence.
Investigators have said her mishandling of evidence may have tainted cases involving as many as 40,000 people, shaking the foundations of the state's criminal justice system. More than 300 people convicted of drug violations have been released from prison as a result, and many others are seeking retrials.
The Supreme Judicial Court ruled last year that the state shares blame for Dookhan's misconduct, and that the court could mull a "systemic approach" to addressing the aftermath.
Any decision by the court deriving from Thursday's hearing could set a national precedent on how to handle convictions that were based on evidence from crime labs later found to have flawed practices.
The Massachusetts Inspector General said the state ignored warning signs throughout Dookhan's tenure, including the fact that in the first two years on the job she tested more than 8,000 samples a year, more than double her next-most productive colleague.
