As many have noted, the Supreme Court’s decision yesterday in Medellin v. Texas raises serious questions about the binding nature of United States’s treaty commitments. The Court holds as follows: “Because none of these treaty sources creates binding federal law in the absence of implementing legislation, and because it is uncontested that no such legislation exists, we conclude that...

Let me begin my final post with a heartfelt thank you to Chris Borgen, Opinio Juris, and all the participants in the forum for a remarkable conversation about my article, Treaties’ End. The conversation has touched on a wide range of issues that deserve much deeper treatment than I can give them here. I will just briefly mention several...

David and Marty have hit on what is probably the most counter-intuitive claim of the article. I argue that congressional-executive agreements create more reliable commitments than Article II treaties, both because they are more likely to be enforced and because they can be more difficult for a single branch of government to unilaterally undo. First let me note a...

David and Curt both raise interesting points that I’d like to address. First, David worries that I am too quick to dismiss the Founders’ concerns. I argue in my article that the Founders decided to place responsibility for concluding treaties in the hands of the President and the Senate alone for two central reasons. First, it was expected that the...

Cathy and Roger both pick up on the special role that human rights treaties play in the history of international lawmaking in the United States. In my article, I argue that the current bifurcated system of international lawmaking took its shape over the course of the twentieth century. The United States gradually abandoned the mercantilist, protectionist trade policy that it...

As David Golove and Marty Lederman note in their post, I argue in my article that one important advantage of congressional-executive agreements over Article II treaties is their stronger democratic legitimacy. I want to say a few more words on the grounds for this claim. The Treaty Clause provides that agreements are made by the President with the "advice and consent"...

Chris makes several excellent points about the value of comparative research. I think it is worth mentioning that I came to this topic from the comparative perspective rather than the other way around. I have for four years now been working on a project in which I am examining the international and domestic lawmaking processes of the 186...

The process for making binding international agreements in the United States proceeds along two separate but parallel tracks. The Treaty Clause—which requires a two-thirds vote in the Senate and bypasses the House of Representatives—is the better known of the two; it is principally used to conclude agreements on human rights, taxation, environment, arms control, and extradition. But an increasingly...
