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).

Some opinion descriptions were drafted by the OLC, some were prepared by Knight First Amendment Institute staff, and some were generated using AI tools.

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.

  • Suing to Enjoin the Enforcement of a Senate Committee's Subpoena

    This opinion addressed whether the Justice Department could have sued to prevent the Senate Judiciary Committee from seeking files on criminal investigations, which included grand jury materials, internal memoranda, and information gathered during investigations. The OLC opinion explained that the Speech or Debate Clause of the Constitution “almost certainly bars” a suit seeking to prohibit the issuance of a Congressional subpoena, although it would not bar a suit against Congressional employees who attempted to enforce the subpoena. The OLC also warned that a preemptive suit might not have been successful because “courts are reluctant to intervene in disputes between the executive and Congress until they are convinced that the other two branches are at loggerheads.”

  • Commercial Salmon Fishing Rights of Hoopa Valley Reservation Tribes

    The document discusses the establishment of the Hoopa Valley Reservation and the tribal rights to fish for salmon. It outlines the history of the reservation and the reasons for its establishment, as well as the federal policy of encouraging Indian agriculture while promising that the Indians would not be dependent on game and fish for food. The document also mentions the 1891 Executive order, which guaranteed a tribal right to fish for subsistence purposes. However, there are no court decisions recognizing a tribal right to fish commercially for salmon on the reservation. The document presents questions about the existence of a tribal right to fish commercially for salmon on the reservation and the implications of the 1891 Executive order.

  • The Constitutional Privilege for Executive Branch Deliberations: The Dispute with a House Subcommittee over Documents Concerning the Gasoline Conservation Fee

    This document presents the executive branch's response to a House Subcommittee's demand for certain documents concerning the Gasoline Conservation Fee. The memorandum confirms the executive branch's views on the legitimacy of withholding deliberative materials from Congress and the public. The conclusion reached is that the President has the power to protect the confidentiality of deliberations within the executive branch. The document also outlines the duty of each branch to attempt to accommodate the legitimate needs of the other, and the need for Congress to articulate its specific legislative need for the requested information. The executive branch acknowledged the Subcommittee's legitimate interest in the information and offered various accommodations, while also being prepared to release additional documents if the Subcommittee's need outweighed the executive branch's interest in maintaining their confidentiality. The document raises questions about the constitutional privilege for executive branch deliberations and the duty of each branch to accommodate the legitimate needs of the other.

    The document discusses a request from Congressman Jack Edwards for the Department of Justice to prosecute the mailing of pro-abortion materials, which is prohibited by 10 U.S.C. 1461.

The conclusion reached is that the relevant portion of 10 U.S.C. 1461 is unconstitutional, and the document raises the question of how the Department of Justice should proceed in enforcing laws it deems unconstitutional.
