United States Office of the Independent Counsel was an independent prosecutor — distinct from the Attorney General of the United States Department of Justice — that provided reports to the United States Congress under 28 U.S.C. § 595. The office was terminated in 1999 and replaced by the U.S. Department of Justice Office of Special Counsel.
In 1978, a Democratic Party-majority Congress was determined to curb the powers of the President and other senior executive branch officials due in part to the Watergate scandal and related events such as the Saturday Night Massacre. They drafted and passed the Ethics in Government Act of 1978, creating a special prosecutor (later changed to Independent Counsel) position, which could be used by Congress or the Attorney General to investigate individuals holding or formerly holding certain high positions in the federal government and in national Presidential election campaign organizations.
The prosecutor, who was appointed by a special panel of the United States Court of Appeals for the District of Columbia Circuit, could investigate allegations of any misconduct, with an unlimited budget and no deadline, and could be dismissed only by the Attorney General for "good cause" or by the special panel of the court when the independent counsel's task was completed. As the president could not dismiss those investigating the executive branch it was felt that the independence of the office would ensure impartiality of any reports presented to Congress. However, there have been many critics of this law including Supreme Court Justice Antonin Scalia. Many argued the new Independent Counsel's office was a sort of "fourth branch" of government that had virtually unlimited powers and was answerable to no one. However, the constitutionality of the new office was ultimately upheld in the 1988 Supreme Court case Morrison v. Olson.
