About 10 convicts can go free while their legal challenges are pending in the fallout from a Massachusetts drug lab scandal.

Suffolk Superior Court Judge Christine McEvoy made the rulings Monday in a Boston courtroom during the first of a series of special sessions to hear cases involving chemist Annie Dookhan. McEvoy set bail for about 10 convicts after prosecutors agreed to put their sentences on hold.

Dookhan has been charged with obstruction of justice for allegedly skirting protocol and faking test results at the now-closed state drug lab. State police say she tested more than 60,000 drug samples involving 34,000 defendants during her nine years at the Boston lab.

Special court sessions have been set up statewide for judges to hear hundreds of legal challenges prompted by the scandal.
