Executive orders, explained

An executive order directs the federal executive branch, but it cannot replace Congress’s lawmaking power.

An executive order is a written directive signed by the U.S. president that directs federal agencies and executive-branch officials. It is not legislation: according to the Congressional Research Service, an order with legal effect must rest on the president’s Article II powers or authority Congress delegated by statute.

That limit defines its reach. The American Civil Liberties Union notes that an executive order cannot override a federal statute or replace Congress’s process for passing one.

What an executive order can do

Executive orders manage executive-branch operations and direct officials’ work, according to the Federal Register. They can instruct agencies to review or revise policy, prepare a report, conduct an investigation or begin work on a regulation.

Article II gives the president executive power and requires that the laws be faithfully executed, the ACLU explains. In other cases, Congress has delegated power to the president through a statute; CRS says either source can support an order’s legal effect.

An order cannot create a new statute without congressional authorization, spend money Congress has not appropriated, take powers assigned to Congress or the courts, or violate the Constitution.

Executive order versus a law passed by Congress

  • Who issues it: The president signs an executive order. A statute must pass Congress and be signed by the president, unless Congress overrides a veto.
  • Authority: An executive order relies on existing constitutional authority or authority Congress delegated. A statute is an act of Congress.
  • Money: The president cannot use an order to authorize spending that Congress has not appropriated, according to Harvard Kennedy School’s explainer.
  • Duration: CRS says a president may generally amend, rescind or revoke an earlier executive order, including one issued by a prior administration.

From signature to action

  1. Drafting and review: CRS describes a typical process involving the Office of Management and Budget, affected agencies, the Attorney General and the Office of the Federal Register. It also notes that not every order follows that process.
  2. Signature: The president signs the directive. The ACLU says some orders take effect upon signing, depending on their terms.
  3. Agency follow-through: Many orders require agencies to take later steps, such as preparing reports, investigating, revising policy or issuing regulations. Those steps can take months or years, according to the ACLU.
  4. Publication: After signing, the White House sends the order to the Office of the Federal Register, which assigns a consecutive number and publishes it in the daily Federal Register. The Federal Register says publication follows signing by at least a day.

Read the order’s instruction separately from its eventual result. An order directing an agency to consider a rule or deliver recommendations begins a process; further agency action may be needed before a regulation takes effect.

How executive orders can be checked

Courts: CRS says courts can review whether the president had authority to act, the scope of Congress’s delegation, the scope of the order and constitutional questions. The American Constitution Society says a party with standing may challenge an order in federal court and seek to block its enforcement.

Congress: Congress can enact a law affecting executive action when it has authority to legislate on the subject, according to the ACLU. CRS says Congress may also nullify the legal effect of an order issued under power it delegated, while the American Bar Association notes that Congress can make an order difficult or impossible to carry out by removing funding.

A president: A sitting or later president may amend, rescind or revoke an existing order, CRS says.

Executive orders, proclamations and memoranda

Presidents issue other written directives. The American Bar Association says proclamations commonly communicate matters including holidays, commemorations, federal observances and trade, while administrative documents such as memoranda, notices and letters can address federal administrative matters.

CRS found no clear substantive distinction among executive orders, proclamations and executive memoranda beyond their titles. Whatever the form, a directive needs a valid presidential source of authority to have legal effect.

How to find an executive order

Search using the order number, title, signing date or issuing president. The Federal Register publishes executive orders and allows browsing by president and year; it says researchers should verify legal research against an official edition or official PDF. The American Bar Association says the National Archives also maintains a searchable index by date, number and topic.

When reading an order, identify the agencies or officials addressed, the authority cited near the opening, the deadlines and instructions, and any provisions on effective dates or implementation. Those details show whether the order acts immediately or requires later agency work.

Frequently asked questions

Can an executive order override a law passed by Congress?

No. The ACLU says an executive order cannot override a federal statute or substitute for Congress’s process of passing a law. CRS says an order with legal effect must rest on constitutional authority or authority Congress delegated.

How can an executive order be stopped or overturned?

A court can find an order unlawful if it conflicts with the Constitution or a federal statute. Congress can legislate on the matter and may affect an order issued under delegated power, while a president may generally amend, rescind or revoke an earlier order, according to CRS and the ACLU.

When does an executive order take effect?

Some orders take effect when the president signs them, depending on their terms. Others require agencies to investigate, prepare reports or issue regulations before their practical effects follow, a process that can take months or years, according to the ACLU.

What is the difference between an executive order and a presidential proclamation?

The American Bar Association says executive orders direct federal-government operations, while proclamations commonly communicate matters such as holidays, observances and trade. CRS says the titles alone do not create a clear substantive legal distinction, and either form needs valid presidential authority to have legal effect.
