SPRINGFIELD, Ill. (AP) -- A former appellate judge reviewed the program at Quinn's request after the governor shut it down.
The full report will be released Friday afternoon. Quinn's office released some of his findings in advance of the report's release.
The so-called "MGT Push" program lowered the prison population by granting good-conduct credit -- or "meritorious good time" -- upfront. More than 1,700 inmates -- hundreds of them violent -- were released weeks early.
The report said the department discarded a policy requirining inmates to earn credits over at least 60 days in custody. And, it says corrections didn't notify local authorities ofthe pending releases.
