The Justice Department’s ethics office has recommended reversing the Bush administration and reopening nearly a dozen prisoner-abuse cases, potentially exposing Central Intelligence Agency employees and contractors to prosecution for brutal treatment of terrorism suspects, according to a person officially briefed on the matter.

The recommendation by the Office of Professional Responsibility, presented to Attorney General Eric H. Holder Jr. in recent weeks, comes as the Justice Department is about to disclose on Monday voluminous details on prisoner abuse that were gathered in 2004 by the C.I.A.’s inspector general but have never been released.
