A presidential memorandum is a written directive from the President to federal agencies and officials that carries the same legal weight as an executive order. The Office of Legal Counsel put it plainly in a 2000 opinion: “there is no substantive difference in the legal effectiveness of an executive order and a presidential directive that is not styled as an executive order.” The difference is procedural. Memoranda face fewer formal requirements for publication and numbering, which makes them a faster, more flexible tool for managing the executive branch. Presidents use them to set agency policy, certify intelligence operations, trigger foreign-aid conditions, and handle administrative tasks that would otherwise require the heavier machinery of an executive order.
How It Differs From an Executive Order
The legal substance is the same. The paperwork is not. Executive orders must be published in the Federal Register and receive sequential numbers (Executive Order 12866, Executive Order 14192, and so on) that make them easy to find and cite. Memoranda have no established numbering system. A memorandum only needs to be published in the Federal Register if it has “general applicability and legal effect” on the public; purely internal directives to agency managers can stay unpublished.1Office of the Law Revision Counsel. 44 USC 1505 – Documents to Be Published in Federal Register
That gap creates real tracking problems. Some memoranda never appear in any public repository. Where they are published, they land in the Daily Compilation of Presidential Documents and the Public Papers of the Presidents, organized by date rather than by number. The count of memoranda issued by any given president depends partly on which tracking methodology you use.
The choice between the two instruments is often a matter of packaging. Presidents have reissued the substance of a memorandum as an executive order, and vice versa, purely for political optics: executive orders sound more decisive even though the legal effect is identical.
How It Differs From a Proclamation
Proclamations are the most ceremonial of the three presidential instruments. They declare national days of observance, order flags flown at half-staff, or mark anniversaries. Most carry no binding legal effect. The exceptions are proclamations with statutory teeth, such as tariff proclamations under trade law or emergency declarations, where Congress has specifically authorized the President to act through that form. A memorandum almost always directs some concrete agency action rather than making a public declaration.
The Main Types of Memoranda
Not every presidential memorandum does the same thing. Three varieties dominate, and the type determines what legal requirements attach.
Presidential determinations are formal findings the President must make before a specific action can proceed under a statute. Foreign-aid disbursements, arms sales, and sanctions waivers frequently depend on the President certifying that a recipient country meets criteria Congress has set. Determinations must be published because they trigger concrete legal consequences.
Presidential findings arise in intelligence and national security. Federal law bars the President from authorizing covert action unless a written finding establishes that the operation “is necessary to support identifiable foreign policy objectives of the United States and is important to the national security of the United States.” Congressional intelligence committees must be notified, but the finding itself is classified and does not appear in the Federal Register.2Office of the Law Revision Counsel. 50 USC 3093 – Presidential Approval and Reporting of Covert Actions
General administrative memoranda are the most common type. They instruct agency heads on policy implementation: directing the Secretary of Labor to update workplace safety guidance, telling the Department of the Interior to review land-use policies, ordering a government-wide hiring freeze. They range from sweeping policy shifts to routine housekeeping.
Where the Authority Comes From, and Where It Stops
The power to issue memoranda flows from Article II, which vests “the executive power” in the President.3Legal Information Institute. U.S. Constitution – Article II Combined with the duty to “take care that the laws be faithfully executed,” that clause gives the President broad power to direct how federal agencies carry out their responsibilities. Broad is not unlimited. When Congress delegates regulatory authority to the executive branch, the delegation must include meaningful boundaries, and courts have struck down laws that hand the executive essentially blank-check authority.
The most influential framework for judging whether a president has overstepped comes from Justice Jackson’s concurrence in Youngstown Sheet & Tube Co. v. Sawyer (1952). Jackson sorted presidential power into three tiers. When the President acts with express or implied congressional authorization, executive power sits “at its maximum.” When Congress has neither authorized nor prohibited the action, the President operates in a “zone of twilight” where legality depends on the circumstances. When the President acts against the expressed will of Congress, presidential power hits “its lowest ebb” and courts will scrutinize the action closely.4Congress.gov. ArtII.S1.C1.5 The President’s Powers and Youngstown Framework The framework applies to memoranda and executive orders alike.
Before a memorandum is finalized, the Office of Legal Counsel within the Department of Justice reviews the draft for legal sufficiency. OLC’s job is to flag conflicts with existing statutes or constitutional constraints before the President signs. It is an internal executive branch check, not an independent one, though OLC opinions have historically blocked or narrowed proposed executive actions.
When It Gets Published, and When It Doesn’t
Publication turns on a single question: does the memorandum affect the public, or does it only affect the internal workings of the executive branch? Under 44 U.S.C. ยง 1505, documents with “general applicability and legal effect” must be published in the Federal Register, and any document “which prescribes a penalty” is automatically treated as having general applicability.5Office of the Law Revision Counsel. 44 USC 1505 – Documents to Be Published in Federal Register A memorandum changing how agencies interact with the public, imposing new requirements on private parties, or altering benefit eligibility must go through the Federal Register. A memorandum telling agency heads to submit quarterly performance reports does not.
Even unpublished memoranda are not supposed to vanish. Under the Presidential Records Act, the President must “take all such steps as may be necessary to assure that the activities, deliberations, decisions, and policies that reflect the performance of the President’s constitutional, statutory, or other official or ceremonial duties are adequately documented” and preserved as presidential records.6National Archives. Presidential Records (44 USC Chapter 22) When a president leaves office, the Archivist of the United States takes custody and has a duty to make the records available to the public as rapidly as possible.7GovInfo. 44 USC 2203 – Management and Custody of Presidential Records
Can You Challenge a Presidential Memorandum in Court?
A memorandum issued under valid constitutional or statutory authority binds every federal agency and employee it addresses. Noncompliance can lead to internal discipline, budget consequences, or removal. Binding force does not depend on the document’s label. It depends on whether the President had the authority to issue the instruction.
A critical limitation shapes how you can push back. The President is not an “agency” under the Administrative Procedure Act. The Supreme Court established this in Franklin v. Massachusetts (1992), holding that “out of respect for the separation of powers and the unique constitutional position of the President,” the Court would not subject presidential actions to APA review without an express statement from Congress.8Legal Information Institute. Franklin v. Massachusetts, 505 US 788 (1992) You cannot challenge a memorandum by filing an APA claim the way you would challenge a regulation issued by the EPA or the Department of Labor.
Challengers must find other legal hooks, typically constitutional claims. Federal courts have blocked presidential directives that violate equal protection, due process, or exceed the scope of delegated statutory authority. In Stone v. Trump, a federal court enjoined military policy directives after finding they likely violated equal protection and due process. Courts do not hesitate to issue injunctions against presidential directives that cross constitutional lines, but the procedural path is narrower than challenging a standard agency rule.
How Memoranda End
A memorandum stays in effect until a president (or a successor) amends, supersedes, or explicitly revokes it. New administrations routinely wipe out the previous president’s directives in bulk, sometimes on inauguration day. Executive Order 14018, for example, revoked a series of prior presidential actions including specific memoranda from the preceding administration.9Federal Register. Executive Order 14018 – Revocation of Certain Presidential Actions There is no rule that a memorandum must be revoked by another memorandum. An executive order can revoke a memorandum and vice versa, because the two legal instruments are interchangeable.
Courts can end a memorandum’s practical life by issuing an injunction. Congress can end it by cutting off the funding needed to implement it.
How Congress Pushes Back
The Congressional Review Act, which lets Congress disapprove agency rules through a fast-track process, does not apply to presidential memoranda. Because the CRA covers “rules” issued by a “federal agency,” and the President is not an agency under the APA’s definitions, presidential actions fall outside the CRA’s reach entirely.10Congress.gov. The Congressional Review Act (CRA): A Brief Overview Congress cannot use its most streamlined disapproval tool against a memorandum.
What Congress can do is control the money. No memorandum can force the spending of funds Congress has not appropriated, and no president can withhold funds Congress has directed be spent. The Impoundment Control Act of 1974 requires the President to send a special message to Congress before proposing to cancel or delay appropriated funds. For a permanent cancellation, Congress has 45 days to act; if Congress does not approve the rescission, the funds must be released for their intended purpose.11Office of the Law Revision Counsel. 2 USC 683 – Rescission of Budget Authority A memorandum directing agencies to freeze or redirect congressionally appropriated funds without following these procedures is, in practice, unenforceable, and the officials who carry it out risk violating the Antideficiency Act, which carries criminal penalties.
The power of the purse is the most effective congressional check on presidential memoranda. A president can sign a memorandum creating a new policy initiative in an afternoon. If Congress refuses to fund it in the next appropriations bill, the initiative dies regardless of what the memorandum says.
