Treaties and Executive Agreements in the United States

In the United States, treaties and executive agreements are two ways of making binding international agreements, but they follow different domestic approval procedures. A treaty in the US constitutional sense requires presidential action and Senate consent, whereas an executive agreement rests on other constitutional or statutory authority without that treaty-specific Senate procedure. International law uses the term treaty more broadly, so the domestic label does not by itself determine an agreement's international legal status.

The constitutional treaty procedure

Article II, Section 2, Clause 2 empowers the President to make treaties with the advice and consent of the Senate, provided two-thirds of senators present concur.

• The President negotiates treaties and submits them to the Senate for consent; Senate consent authorises, but does not compel, the President to complete ratification.
• The House of Representatives has no formal role in giving treaty consent, although legislation or appropriations needed to implement a treaty may require its participation.
• The Senate may attach reservations, understandings or declarations to its consent.

The authority behind executive agreements

Executive agreements do not require the Article II two-thirds Senate vote. Their legal basis varies, so the term does not mean that the President always acts alone.

• A congressional-executive agreement is authorised or approved through legislation passed by both houses of Congress.
• A treaty-based executive agreement draws authority from an existing treaty.
• A sole executive agreement rests on the President's independent constitutional powers and must remain within their limits.
• The executive-agreement route does not confer unlimited power to bypass Congress or disregard constitutional allocations of authority.

Legal effect and continuity

The central distinction concerns domestic authority and approval, not an automatic difference in international binding force.

• Article VI includes treaties made under US authority within the supreme law of the land, but a treaty cannot override the Constitution.
• A self-executing treaty can operate as domestic law without implementing legislation; a non-self-executing treaty requires legislative implementation for domestic enforcement.
• An executive agreement's domestic effect depends on its legal basis; the label alone does not establish its priority over federal legislation.
• Executive agreements are not automatically temporary or extinguished by a change of President; withdrawal depends on the agreement's terms and applicable legal authority.
