This story from the NY Times (11/7/07) about a Justice Dept. official who submitted to waterboarding to see what it was like suggests that the Justice Dept. may have had several different opinions from the counsel's office on the practice, but only one was good enough for the Bush Administration.

The man who tried it out did this:

After his waterboarding, Mr. Levin went on to sign a new legal opinion on the limits of interrogation, released on Dec. 30, 2004, that made news with its ringing opening sentence: Torture is abhorrent both to American law and values and to international norms. That memorandum replaced a much-criticized opinion written in August 2002, which had defined torture as treatment producing pain equivalent to organ failure or death and had suggested that a president might be able to authorize torture under his constitutional war powers....

After writing the opinion denouncing torture, Mr. Levin...was told by Alberto R. Gonzales, the incoming attorney general, that he would not be nominated to lead the Office of Legal Counsel.
