[JURIST] In court papers filed Friday, US Special Counsel Patrick Fitzgerald [official website] said certain details of his investigation into the CIA leak case [JURIST news archive], including grand jury testimony and documents identifying witnesses, must remain secret, implying that the probe continues to move forward and that further charges may be forthcoming. Fitzgerald did not object, however, to further disclosure of details related to the indictment of I. Lewis "Scooter" Libby [NYT profile], Vice President Dick Cheney's former chief of staff. Dow Jones & Company [corporate website], publisher of The Wall Street Journal, has filed a petition for the release of secret details of Fitzgerald's investigation. The issue centers around eight blank pages contained in the public version of the Feb. 15, 2005 ruling [text, PDF] by the US Court of Appeals for the DC Circuit [official website] in which Circuit Judge David Tatel affirmed that former New York Times reporter Judith Miller and TIME reporter Matthew Cooper could be held in contempt of court [JURIST report] for failing to testify in the case.
