As reports circulate that the Justice Department has softened its criticism of attorney John Yoo for memos approving the Bush administration’s treatment of terrorism suspects, several prominent lawyers are urging a federal appeals court in San Francisco to hold Yoo accountable.

They have submitted arguments opposing dismissal of a prisoner’s lawsuit that accuses the former Justice Department attorney of providing a legal cover for torture. The suit covers much of the same ground as the department’s ethics investigation of Yoo.
