Treaty-making power

Treaty-making power is a shared constitutional authority, designed to combine the President’s capacity to conduct foreign negotiations with the Senate’s participation in decisions that bind the nation. The essays defend the requirement that two-thirds of senators present concur not as an incoherent mixture of branches, but as a safeguard suited to treaties’ unusual character: agreements with foreign powers that carry the force of law and concern war, peace, and commerce.

Constitutional design and the treaty threshold

The proposed Constitution gives the President power, by and with the Senate’s advice and consent, to make treaties, provided two-thirds of the senators present concur. Critics object that the authority is divided between branches, that the Senate is too small a body, or that the House of Representatives should also participate. Others would require two-thirds of the entire Senate rather than two-thirds of those present. The defense of the plan treats these objections as distinct questions: who can negotiate effectively, who should share responsibility for a consequential agreement, and what decision threshold can secure deliberation without making action impracticable.

The arrangement sits within a broader constitutional structure in which federal laws and treaties made under the Constitution are supreme law of the land. That supremacy, the essays argue, is limited by the requirement that federal action be pursuant to constitutional authority. The rule does not convert an unauthorized act into valid law: an act that invades powers left to the states is usurpation, not a legitimate exercise of national supremacy. Treaty-making therefore belongs to a scheme of delegated powers and constitutional limits, not to an unlimited authority to bind the country by any means.

Why treaties occupy a distinct constitutional category

The essays resist assigning treaty-making exclusively to either the legislative or executive department. Legislation prescribes rules for society; executive power carries existing laws into effect and employs the common strength for public purposes. A treaty does neither in the ordinary sense. It is a contract with a foreign nation, binding through good faith, rather than a rule imposed by a sovereign on its subjects. Its character is consequently distinct, even though its obligations have the force of law.

That distinctive character supports a divided procedure. The executive is described as the most suitable agent for foreign negotiations, while the importance of the trust and the legal operation of treaties argue for participation by all or part of the legislature. The constitutional plan thus does not treat negotiation and consent as interchangeable tasks: it entrusts the conduct of negotiations to the President while requiring the Senate to concur before a treaty is made.

The President and Senate as mutual safeguards

The case against giving the President sole treaty-making authority rests on the nature of an elected chief magistrate. Unlike an hereditary monarch, an elected President may have a moderate or slender fortune and expect to return to private life after a four-year term. The essays identify the resulting vulnerability as a political risk: an avaricious President might trade the country’s interests for wealth, while an ambitious one might seek personal advancement with foreign assistance. The argument is not that every President would betray the public, but that the delicacy and importance of foreign relations make sole reliance on individual virtue unsafe.

The Senate alone, however, would lose the benefits of the President’s constitutional role in negotiation. If the Senate could choose whether to employ the President as its agent, pique or cabal might lead it to dispense with his participation. A negotiator acting merely as the Senate’s servant would also lack, in the essays’ account, the confidence and standing abroad of a constitutional representative of the nation. The President’s participation supplies negotiating authority and national weight; Senate concurrence supplies an additional restraint. Joint possession of the power is presented as safer than its exclusive possession by either institution.

The defense also rejects adding the House of Representatives to treaty formation. The House’s large and changing membership is said to be poorly suited to sustained foreign policy. The essays name the demands of the task—comprehensive knowledge of foreign politics, continuity of outlook, sensitivity to national character, decision, secrecy, and dispatch—and contrast them with a body whose composition fluctuates and is expected to grow. Requiring another institution’s concurrence would multiply the stages of agreement, keep the House assembled longer, and add inconvenience and expense. The objection is therefore not merely that the House is larger: its scale and changing composition are judged incompatible with the particular work of negotiation and treaty approval.

Responsibility, appointment, and public accountability

The treaty arrangement forms part of a wider argument that divided authority need not dissolve responsibility. In the proposed appointments process, the President’s nomination is distinct from the Senate’s judgment on it. The public can identify the actors and assign blame: a bad nomination is chargeable to the President; rejection of a good one to the Senate; and an appointment that both nominate and approve reflects on each, though in different degrees. This visible division is contrasted with New York’s appointment council, a body of three to five people that meets privately and leaves uncertain who proposed or resisted a choice. There, the indeterminate authorship of appointments weakens public censure and opens room for intrigue.

This emphasis on identifiable responsibility complements the essays’ warning against multiplying executive authority. When several magistrates share executive power, mutual accusations can obscure who caused a harmful measure, leaving public opinion uncertain about the true author. A single executive, by contrast, makes responsibility more legible; institutional checks can restrain that officer without concealing who acted. Treaty-making follows a related logic: participation is divided, but the constitutional roles are specified so that the public can see where nomination, negotiation, and consent reside.

The larger principle is that constitutional protections must be matched to the risks they are meant to control. The essays describe ambition as a force that can counteract ambition, connecting officials’ personal incentives to the constitutional rights of their offices. Popular dependence remains the primary control on government, but experience calls for auxiliary precautions. In treaty-making, the President’s negotiating role and the Senate’s power to withhold concurrence are such precautions: neither office is trusted with the entire decision, and their cooperation is made visible as a condition of national action.

Constitutional meaning and the limits of authority

The treaty clause’s placement within a written constitution matters because the essays treat federal authority as delegated rather than inherent and unlimited. The Constitution’s supremacy provision applies to treaties made by federal authority, but the broader explanation of supremacy insists that only acts pursuant to constitutional powers qualify. Just as an attempt by the federal legislature to alter a state’s law of descent or abolish a state land tax would exceed its jurisdiction, national supremacy cannot validate action beyond the authority granted. The analogy clarifies the interpretive boundary: a treaty’s importance does not remove it from the constitutional order that authorizes and limits federal action.

The essays also explain why written declarations may be included even when their substance would follow by necessary implication. The Necessary and Proper Clause authorizes laws needed to execute the powers vested in the national government, while the supremacy provision identifies the status of constitutional federal laws and treaties. The argument calls such language declaratory rather than an independent enlargement of power: it makes explicit a consequence of creating a federal government with specified authority and guards against later attempts to evade or curtail that authority. The treaty clause is thus defended within a general method of reading the Constitution through its powers, structure, and necessary implications, rather than treating every broad-sounding phrase as a boundless grant.

The account’s institutional logic is consistent across its subjects. Courts, too, must remain independent to preserve constitutional limitations; in a limited Constitution, they must be able to treat acts contrary to its manifest tenor as void. That discussion does not assign courts the treaty-making function, but it reinforces the premise that no department’s action escapes constitutional scrutiny simply because it carries public authority. Treaty-making combines executive competence with legislative participation, while constitutional limits define the boundaries within which both may act. Its decisive significance lies in that combination: foreign agreements receive an effective national voice without being entrusted to a single officer or detached from the people’s constitutional framework.
