The OLC's Opinions

Opinions published by the OLC, including those released in response to our FOIA lawsuit

This Reading Room is a comprehensive database of published opinions written by the Justice Department’s Office of Legal Counsel (OLC). It contains the approximately 1,400 opinions published by the OLC in its online database and the opinions produced in Freedom of Information Act litigation brought by the Knight Institute, including opinions about the Pentagon Papers, the Civil Rights Era, and the War Powers Act. It also contains indexes of unclassified OLC opinions written between 1945 and February 15, 1994 (these indexes were created by the OLC and intended to be comprehensive). We have compiled those indexes into a single list here and in .csv format here. This Reading Room also contains an index of all classified OLC opinions issued between 1974 and 2021, except those classified or codeword-classified at a level higher than Top Secret (the OLC created this index, too, and intended it to be comprehensive).

The Knight Institute will continue updating the reading room with new records. To get alerts when the OLC publishes a new opinion in its database, follow @OLCforthepeople on Twitter.

  • Executive privilege

    This opinion articulated the OLC’s argument in defense of executive privilege, which it traced to 1792. The opinion explained that the “underlying rationale” for the privilege was that “in the area of executive decision-making the President must be free to receive from his advisers their candid opinions without the fear that they will be second-guessed either by Congress, the press, or the public.”

  • Power of Congressional Committee to Compel Appearance or Testimony of Presidential Assistant

    The OLC provided several examples of presidential assistants that refused to testify before Congress on the basis that the president advised him not to appear. The opinion then concluded that, if Congress moved to hold the advisor in contempt, the advisor could ignore an indictment or warrant of arrest. However, the OLC went on to explain that in the alternative, an advisor could move to dismiss an indictment or seek a declaratory judgment stating that he need not appear before Congress.

  • Appearance of Presidential Assistant Peter M. Flanigan before a. Congressional Committee

    This opinion concludes that Peter M. Flanigan, Assistant to the President, can decline to appear before the Senate Committee on the Judiciary, since the president's immediate staff share his immunity from Congressional process, unless the inquiry is related to their private conduct. The opinion also includes three historical examples when presidential assistants refused to appear before a Congressional committee. The OLC does not provide release dates for its opinions, so the release date listed is the date on which the opinion was authored.

  • Immunity of Presidential Assistants from being required to testify before Congressional Committees

    This memo, which accompanied a previously-published memo transmitted to the White House counsel on the same day, explained that presidential assistant Peter Flanigan would not appear before Congress if invited to testify. The OLC argued that refusals to testify on their official duties were “fundamental to our system of government.”

  • Criteria for Denial of White House Press Passes

    In this memo, the OLC responded to a request for its views regarding the legal implications of the denials of White House press passes to certain applicants because they were not cleared by the Secret Services for security reasons. The OLC concluded that if a court reached the merits of such a case, it would require some intermediate version of a hearing, not a full adversarial hearing, but “notice of the specific charges and an opportunity to respond.”

  • Micronesian Negotiations

    The opinion determines that Congress can relinquish powers over territorial status and give what was once a territory, such as Micronesia, a measure of self-government through a mutual agreement that will bind future Congresses. The OLC does not provide release dates for its opinions, so the release date listed is the date on which the opinion was authored.

  • Criminal Prosecution for Disclosure of Classified Information Relating to Defense Department Vietnam Study

    This memo, written shortly after the Supreme Court’s decision allowing the publication of the Pentagon Papers to continue, analyzed the Justice Department’s possible paths to “prosecuting government employees, private citizens, reporters, and newspaper entities” involved in the papers’ publication. It concluded that newspapers might be subject to criminal liability under 18 U.S.C. § 793, and potentially 18 U.S.C. § 2 and 18 U.S.C. § 371, although ultimately the Justice Department only prosecuted Daniel Ellsberg and Anthony Russo.

  • Permanent Injunctive Relief Against the Publication of the Defense Department Vietnam Study by the New York Times

    This memo opined that the attorney general did not need to rely on specific statutory authorization to seek an injunction against the continued publication of the Pentagon Papers, but would likely need to demonstrate “irreparable damage to the national security” in order to succeed. It suggested that the Justice Department argue that the publication of “top secret” documents would be sufficient to show irreparable damage, which, if accepted, would have given the government broad power to obtain prior restraints against reporting about national security.

  • Authority to Use Troops to Prevent Interference With Federal Employees by Mayday Demonstrations and Consequent Impairment of Government Functions

    The President has inherent constitutional authority to use federal troops to ensure that Mayday Movement demonstrations do not prevent federal employees from getting to their posts and carrying out their assigned government functions. This use of troops is not prohibited by the Posse Comitatus Act. The OLC does not provide release dates for its opinions, so the release date listed is the date on which the opinion was authored.
