Executive orders are one way the President may accomplish tasks without waiting for Congressional approval. They carry the full weight of the law and are subject to reversal by the Judicial System. It allows the President to ensure that laws and actions are being carried out by Executive Departments (such as the Department of the Interior or the Department of Defense).
A Brief History
Executive Orders have been used by every chief executive since the time of George Washington. Most of these directives were unpublished and were only seen by the agencies involved. In the early 1900s, the State Department began numbering them; there are now over 13,000 numbered orders. Orders were retroactively numbered going back to 1862 when President Lincoln suspended the writ of habeas corpus and issued the Emancipation Proclamation by Executive Order. There are also many other Executive Orders that have not been numbered because they have been lost due to bad record-keeping. Such is not the problem today. All new Executive Orders are easily accessible.
Examples of Executive Orders
Many important policy changes have occurred through Executive Orders. Abraham Lincoln issued the Emancipation Proclamation as an EO, and also suspended the writ of habeas corpus. FDR issued Executive Order 9066, authorizing the Secretary of War to designate any area a military zone, and effectively allowing the government to place Japanese Americans residing in those areas in internment camps. Harry Truman integrated the armed forces under Executive Order. President Eisenhower used an EO to desegregate schools. Presidents Kennedy and Johnson used them to bar racial discrimination in federal housing, hiring, and contracting. President Reagan used an EO to bar the use of federal funds for advocating abortion. President Clinton reversed this order when he came into office.
What if Congress doesn't agree?
If Congress does not like what the executive branch is doing, it has two main options. First, it may rewrite or amend a previous law, or spell it out in greater detail how the Executive Branch must act. Of course, the President has the right to veto the bill if he disagrees with it, so, in practice, a 2/3 majority if often required to override an Executive Order.
Congress is less likely to challenge EOs that deal with foreign policy, national defense, or the implementation and negotiation of treaties, as these are powers granted largely to the President by the Constitution. As the Commander-in-Chief of the armed forces, the President is also considered the nation's "Chief Diplomat." In fact, given national security concerns, some defense or security related EOs (often called National Security Directives or Presidential Decision Directives) are not made public.
In addition to congressional recourse, Executive Orders can be challenged in court, usually on the grounds that the Order deviates from "congressional intent" or exceeds the President's constitutional powers. In one such notable instance, President Harry Truman, was rebuked by the Supreme Court for overstepping the bounds of presidential authority. After World War II, Truman seized control of steel mills across the nation in an effort to settle labor disputes. In response to a challenge of this action, the Supreme Court ruled that the seizure was unconstitutional and exceeded presidential powers because neither the Constitution or any statute authorized the President to seize private businesses to settle labor disputes. For the most part, however, the Court has been fairly tolerant of wide range of executive actions.
