Opinio Juris Symposium: "The Constitution's Text in Foreign Affairs"
Opinio Juris is proud to host an online symposium on Michael Ramsey’s new book The Constitution’s Text in Foreign Affairs recently published by Harvard University Press.

We are especially pleased to have Professor Ramsey with us to discuss his book because it is, in my humble opinion, the most important monograph on U.S. foreign relations law in the past decade (one might even say, without hyperbole, that it is the most important U.S. foreign relations book of this century!).

Not since Professor Louis Henkin’s seminal treatise, Foreign Affairs and the United States Constitution has a single work attempted to provide a comprehensive treatment of all of the major constitutional questions raised by the U.S. system of foreign relations. And unlike Henkin’s work, Professor Ramsey attempts to offer a coherent theoretical approach to resolving questions of foreign relations law.

Of course, my comments here do not mean that I necessarily agree with everything in Professor Ramsey’s new book. Indeed, there is much with which I disagree. But there is no doubt in my mind that his book, and the theoretical approach he articulates, must be seriously considered by every scholar and lawyer working in the field of U.S. foreign relations law.

We will begin this morning with a brief opening post by Professor Ramsey. It will be followed by comments on different aspects of his book from three top scholars in this field: Martin Flaherty of Fordham Law School, Andrew Kent of Fordham Law School, and Opinio Juris’ own Peter Spiro of the Beasley Law School at Temple. I will also jump in with questions and comments for both Professor Ramsey and our guest commenters. Other Opinio Juris contributors and readers are, of course, welcome to jump in as well.

We look forward to a lively exchange over the next two days.
Opinio Juris Symposium: Introducing "The Constitution's Text in Foreign Affairs"
[Michael Ramsey is a Professor of Law at the University of San Diego. He will be posting today and tomorrow on his new book: The Constitution's Text in Foreign Affairs. Please stay tuned for his posts, as well as for comments by our other symposium participants.]

Thanks to Opinio Juris for organizing this symposium and inviting me to participate. Here are a few opening thoughts.

The Constitution’s Text in Foreign Affairs (Harvard University Press, 2007) attempts to describe the distribution of foreign affairs powers among the branches of U.S. government on the basis of the Constitution’s words and phrases as understood in the founding era. It’s been said that the Constitution’s text is so incomplete or opaque in foreign affairs that no useful framework can be found there. I argue that it can (though many details can’t be resolved this way and even some bigger issues remain unclear).

It’s important to emphasize that the book is not “originalist” in the sense of claiming that we must follow founding-era understandings. It only contends that many founding-era understandings can be discovered with some degree of confidence. I leave to readers what importance to give them.

The book discusses modern cases and debates in terms of founding-era understandings, but it’s not trying to score political points in today’s controversies. Indeed, it will disappoint both sides on many partisan matters, for it finds that the Constitution’s framers steered a middle course between the extremes on issue after issue – sometimes consciously to create checks and balances, sometimes from practical compromises between positions sharply debated at the time.

In its approach, the book uses what might be called ‘historical textualism.’ It focuses on the Constitution’s specific words and phrases, but with attention to the way they were used before the Constitution’s adoption and how they seem to have been understood afterward. This avoids “plain meaning” literalism that reads text in a vacuum, without attention to context. Context-less literalism tends to make the Constitution seem more opaque or ambiguous that it would have seemed at the time (because it misses meanings context can supply), while also importing modern ahistorical intuitions. The book also rejects abstract “framers’ intent” approaches that claim to understand what the framers would have thought about particular issues from their historical, intellectual and ideological backgrounds. If not anchored in the specifics of the text, that inquiry becomes immensely speculative: even if we can identify the framers’ abstract goals (and often they had competing ones), there are many ways they might have sought to implement them; without close attention to text we will have a hard time saying which way they chose.

Without trying to summarize the entire book, I’ll give three examples of its approach and conclusions.

Opinio Juris Symposium: The President's Residual Power to Use Military Force
[We are very pleased to have Andrew Kent's participation in this online symposium on The Constitution's Text in Foreign Affairs. J. Andrew Kent is an associate professor of law at Fordham University School of Law. Although he is new to the academy, Professor Kent has already published important works in the area of foreign relations law including "A Textual and Historical Case Against Global Constitutionalism", 95 Georgetown L. Rev. 463 (2007) and "Congress's Underappreciated Power to Define and Punish the Law of Nations," 85 Tex. L. Rev. 843 (2007). ]

Like Professor Ramsey’s previous work, I found The Constitution’s Text in Foreign Affairs to be exceedingly thoughtful, careful, even-handed and provocative. I’m a huge fan of Ramsey’s work, including this book. Today’s format, however, suggests I should poke and prod and critique, not flatter. So I will use Ramsey’s discussion of the President’s power to respond to a state of war created by an enemy attack on the U.S. to raise some questions.

The Constitution’s Text argues that when Article II vested “the executive power” in the President, it transferred a knowable, definable quantum of what eighteenth century Americans would have understood to be discretionary power to act independent of the legislature in the realm of foreign affairs. But unlike in the British constitution, the model for many executive power theorists read by the American Founders, the U.S. Constitution gave several key pieces of executive power to Congress as a whole or the Senate, including the power to declare war, issue letters of marque and reprisal, and approve treaties. Ramsey argues that the best meaning of the Constitution is that these exceptional grants of executive power to other branches must be read strictly, and that all residual executive power, not given to Congress or the Senate, went to the President. Ramsey further argues that “declaring war” meant, to an eighteenth century audience, initiating hostilities in the first instance by either word or deed. The President cannot intentionally begin a war, then, when the country is at peace. But all other war powers not given to Congress remain with the President, Ramsey argues. This means, among other things, that when the U.S. is attacked by another country and a state of war thereby created, the President has independent constitutional authority to respond as he chooses.

On this issue, The Constitution’s Text follows through only partially on its textual method; it gives insufficient weight to the Constitution’s truly massive transfer of “executive” war power away from the American Executive. The Declare War Clause and Marque and Reprisal Clause are discussed at length but somewhat in isolation. Many other “executive” war-related powers, clearly granted to Congress by the Constitution, receive shorter shrift in the book’s discussion of force initiation responsibilities – the powers to raise and support armies and navies, make rules and regulations for the armed forces, make rules concerning captures, constitute courts (for condemnation of prizes of war or trial of enemy war crimes, e.g.), call out the militia, impose embargoes and other trade sanctions (Foreign Commerce Clause), and punish offenses against the law of nations. With the exception of the Commander-in-Chief Clause and treaty power, every single identifiable war-related aspect of eighteenth-century “executive power” named in the Constitution is in Article I, not Article II. Since war was, in bulk, given to Congress, and since the Necessary and Proper Clause is also in Article I, why isn’t it textually-structurally more plausible to read the Constitution as commanding the reverse of Ramsey’s default interpretive rule: war powers are congressional unless clearly given to the President?

A large part of Ramsey’s answer relies on the precise wording of the Declare War Clause. Because he interprets “declare” to mean only that Congress may begin war, responding to already existing hostilities is not a declaration and therefore not a congressional power. But this ignores other relevant clause. The Marque and Reprisal Clause authorizes responsive, defensive (as well as offensive) force. When the U.S. is attacked or molested, Congress may strike back by issuing licenses to private seamen to attack the aggressor’s shipping. What becomes this power if an enemy attack automatically triggers the Executive’s power to respond at will with whatsoever amount of force it desires? Congress’s power to calibrate national responses to provocation is lost. Similarly, Congress’s powers to authorize U.S. warships to “capture” foreign vessels and its power to lay embargoes and other retaliatory commercial restrictions – additional powers to respond to provocation in a measured and targeted manner – are substantially vitiated by Ramsey’s reading of the Declare War Clause. Moreover, Congress’s negative power to decide against force as a response to provocation – recognized as crucial by, for example, Washington, Adams, Jefferson, Madison, Marshall, Iredell, Monroe, Gallatin, Gerry, Knox and others – is gone. A complete textual-structural account of war powers must, I think, account for the significance of Congress’s powers to decide whether and when to use responsive force short of war, or even no force at all.

The Constitution’s Text slights illuminating judicial doctrine and post-Founding executive-congressional practice on this issue. Two Marshall opinions are on point. Brown v. United States (1814) showed that the Declare War Clause must be read in light of the Captures Clause. And Little v. Barreme (1804) held that congressional statutes authorizing only limited responses to enemy provocation bind the Executive. Notably, the executive order at issue in Little was an isolated instance where President Adams did not wholly defer to Congress to decide how to respond to France’s Quasi War against us. Similarly, the practice of President Washington in the face of Indian attacks on the U.S. and even formal declarations of war by Indian nations was to allow Congress to decide how to respond. Ramsey’s discusses but steeply discounts these precedents, for reasons with which I do not agree.

For example, he warns that using post-ratification evidence “carries its own caveats and dangers. Once the Constitution was ratified and its government began operating, American leaders developed personal, political, and institutional commitments to views not necessarily founding upon anything in the Constitution’s text” (p.74). Ramsey is particularly wary about any evidence of constitutional meaning from beyond the “immediate post-ratification experiences of 1789-1797” (75), apparently because it is distant in time from the Founding, giving more time for political etc. bias to accrue and linguistic usages to change. As a result, the Constitution’s Text consistently privileges the writings of Europeans who shaped the intellectual worldview of the Founding generation by writing about law, politics and governance before the Constitution was drafted (e.g., Blackstone, Locke, Grotius, Vattel, de Lolme, Montesquieu), over the directly expressed views of Founding generation Americans interpreting the actual Constitution after it was put into practice.

It seems to me, though, much easier and – hence ultimately more accurate – to understand and discount the potential biases of familiar American men (how many volumes do we have by and about Hamilton, Washington, Adams, Jefferson, etc.?) holding familiar government positions than it is to implement Ramsey’s preferred method: doing the difficult work of analysis, inference and translation required to, first, accurately understand eighteenth century British and European politico-legal concepts like “executive power,” “legislative power,” “declare” and “war,” and then understand how Americans assimilated them into their unique world view, and how their meanings would have changed as they were molded and rearranged into the wholly novel U.S. Constitution. Pre-Constitution concepts and language are, of course, vitally important tools of analysis. But not more important, I think, than post-ratification commentary and practice directly on point.

To understand the President’s power to respond to hostilities initiated by others, The Constitution’s Text devotes the same space to Englishman Richard Lee’s little known 1760 treatise on the international law regarding war-time seizures of shipping as it does to the actual practice of government under both the Washington and Adams administrations. If a rock-solid methodological commitment required this choice – say John Yoo’s sometimes-expressed claim that the Constitution’s legitimacy derives only from its adoption by the People in 1787-88, and therefore any post-dated evidence has little value – I could better understand Ramsey’s choice. As it is, he describes his project as attempting to determine the Constitution’s meaning to ordinary Americans at this time of ratification (vii, 8-9). Stated at this level of generality, this goal wouldn’t seem to require the choices about evidentiary weight made in The Constitution’s Text.

I have a few other issues with Ramsey’s discussion of the power of the President to respond to attacks:
Opinio Juris Symposium: Can History Determine Textual Meaning?
[We are pleased to have Martin S. Flaherty as a second participant in the discussion today. Professor Flaherty is the Leitner Family Professor of International Law at Fordham Law School and a Visiting Professor at the Woodrow Wilson School of Public & International Affairs at Princeton University. A widely published scholar in the fields of constitutional law and history, foreign relations, and international human rights law, we are thrilled to have his comments here today.]

Mike Ramsey’s book, The Constitution’s Text in Foreign Affairs, will without question be a major and outstanding contribution to the field of U.S. foreign affairs law. The field itself has never been more important yet is only now benefiting from new, comprehensive, theoretical monographs. The current importance of U.S. foreign affairs law needs little elaboration. Iraq, Afghanistan, the “Global War on Terror,” ongoing detentions in Guantanamo Bar, not to mention globalization, the International Criminal Court, and human rights means that judges, lawyers, and citizens will need to examine this subject as never before. There are, however, almost no works that attempt to present a unified theory of foreign affairs law in the manner commonly seen on the domestic front. Probably the closet thing remains Louis Henkin’s magisterial Foreign Affairs and the Constitution, but his volume is more in the nature of a treatise than a work of constitutional theory.

Ramsey’s approach is original. As he indicates, the conventional wisdom among scholars who agree on little else is that reliance on the Constitution’s text to resolve foreign affairs law disputes is all but quixotic. Ramsey nonetheless offers an approach which points toward answers in an array of current and longstanding disputes that relies on text to a great extent. That said, he admits he must also rely upon history, if only because the meaning of various key texts has been lost. Nonetheless, his reliance on text appears always to remain the point of departure and the book never loses cite of its textual moorings notwithstanding its excursions into history.

The theory that results from this approach is coherent, if ultimately problematic. A certain degree of foreign affairs scholarship, to be sure, also reflects a certain coherence, whether Harold Koh’s emphasis on Congressional power or John Yoo’s focus on executive authority. Much if not most foreign affairs scholarship nonetheless tends to be piecemeal. Even so great a theorist as John Hart Ely, for example, in War and Responsibility did not offer a unified vision of U.S. foreign affairs, but instead concentrated on one aspect, the war power. Ramsey’s book, by contrast, applies an integrated separation of powers model across the board to areas ranging from detention, treaty termination, executive agreements, federalism, war, and torture. Whether one agrees with its prescriptions or not (and in many cases I don’t), it must be said that the theory he constructs rests upon concept that is readily grasped yet wide-ranging.

The results that Ramsey’s approach indicates are surprisingly balanced, both in the context of foreign affairs scholarship and politics more generally. Many of his doctrinal conclusions would enervate “liberals.” The President, for example, would be able to fight undeclared “defensive” wars, to undertake even provocative actions short of war, and to terminate treaties under their terms without Senate approval. Likewise, the powers of the states would not be affected by executive agreements, presidential orders, and customary international law. Yet many of Ramsey’s prescriptions would likely alienate “conservatives.” The President’s “executive” foreign affairs authority would have to be tethered to some enactment, whether treaty or statute. Thus, the President could not unilaterally seize steel mills, order detention or torture, or terminate treaties that did not so allow under their terms. In addition, Ramsey also largely defends a role for the courts in foreign affairs. Finally, the book rightly argues that the exercise of Constitutional authority abroad can be done only subject to the Constitution’s limitations on power, adjusted to various special circumstances overseas.

My major significant qualm about The Constitution’s Text in Foreign Affairs – and fair warning, it is significant — is its use of history.
Opinio Juris Symposium: Thoughts in Response to Professors Flaherty and Kent
Thanks to Professors Flaherty and Kent for their insightful comments. Both of them have done great prior work in illuminating the Constitution’s historical understanding, and I continue to learn from them.

Professor Flaherty’s cautions about history’s ambiguities must always be kept in mind in attempting a project like this. I’ve tried to be clear in the book that I appreciate the difficulties he highlights, and that we are often not able to make definitive conclusions but can only do the best we can with the limited materials available to us. Often we can’t say something was definitely true – only that one interpretation seems more likely than another. Likewise, we can rarely claim that everyone in the founding era (or even every framer) believed certain things: we can only say that one interpretation seems to have been more widely embraced than another.

But with those caveats fully felt and expressed, I think Professor Flaherty and I have some core disagreement about how discoverable history is. I think historical judgments fall on a spectrum: some we can be very confident of (even taking Professor Flaherty’s cautions fully to heart) while others are somewhat more speculative. I’ve tried to indicate in the book where I am relatively more or less confident. For example, I am very confident that the common eighteenth-century understanding of “declaring war” included war-initiation power generally, and thus that the declare war clause gave Congress this power and denied it to the President, and I am not shy about saying so. In contrast, I am a lot less confident that the phrase “the Laws” in the take-care clause of Article II, Section 3 includes the law of nations (and thus give the President the duty to obey the law of nations). But, at the same time, I think we can coherently say that this is a better reading of history than the contrary view (which has little support at all).

Ultimately, though, I think the thing to keep in mind is that my goal is to reach the best understanding of the history, recognizing that this may often be well short of certainty, but also recognizing that there are at least more-likely and less-likely interpretations.

Turning to a specific issue, Professor Kent takes up a particularly difficult one: the President’s power to respond to attacks on the U.S. (Incidentally, for those interested in this issue, my colleague Saikrishna Prakash and I have a forthcoming exchange in the Cornell Law Review on it: he takes Professor Kent’s view, and I respond in some more detail than is given in the book).

Professor Kent faults me for not using more post-ratification history to answer this question, but our disagreement turns more on the existence of specific post-ratification evidence than on the usefulness of post-ratification evidence in general. Although I think post-ratification evidence must be used cautiously, the book makes much use of it (especially, for example, with respect to executive power and war-initiation power). My point is mainly that pre-ratification linguistic evidence is also important, and the best results can be achieved by looking at the two together.

The problem in the response-power issue is that, despite what Professor Kent says, there isn’t much post-ratification evidence, at least not from the Washington and Adams administration. The issue was not squarely presented under Washington. Aside from Indian tribes, there were no attacks on the U.S. With respect to Indian hostilities, on the southeastern frontier there were some isolated raids but Washington did not treat any of these as actually creating a state of war with the U.S., and did not respond in force. On the northwest frontier, Washington responded in force against the Wabash tribes after some large-scale attacks. He asked Congress to approve a military force to deal with these attacks (the U.S. at the time had no standing army, so Congress had to approve raising one). However, Congress did not explicitly approve offensive operations – it’s just not clear whether it was thought to have approved implicitly, or whether approval was not required. The issue also did not come up under Adams: the French seized U.S. merchant ships (supposedly for violations of rules of neutrality) in the run-up to the Quasi-War, but France did not attack the U.S. or U.S. forces. The (limited) war did not start until Congress approved it. This says nothing about Adams’ power had France attacked the U.S. The Tripoli incident in 1801 is the first clear episode raising the issue, and the book discusses it at some length. (Professor Kent and I have different interpretations of it, but the bottom line is that Jefferson’s cabinet – Madison included – approved an offensive response, Jefferson ordered an offensive response, the navy made an offensive response, and Congress, informed of the navy’s instructions, raised no objection). So in the response-to-attack issue, I don’t mean to devalue post-ratification evidence – I just don’t think there is much (and that’s one of the things that makes it hard).

Professor Kent’s comments do contain some element of the kind of abstract intent-oriented reasoning that I find unpersuasive. He says that because the Constitution gave so many formerly executive military powers to Congress, why shouldn’t we presume that it gave basically all military powers to Congress? This, though, is not really a textual argument, because it does not point to any text that actually supports it. It is true, as Professor Kent says, that the Constitution’s framers wanted to shift a huge amount of the formerly executive military power to Congress. But this general statement does not say anything about what the Framers wanted to do with the specific power of response. We can be reasonably sure (from Madison’s comments at the Convention, and from practical necessity in a time when Congress met infrequently) that they wanted to give the President power to respond defensively to attacks (and, as noted above, we can be very confident that they did not want the President to be able to initiate attacks). But moving from this to the claim that they wanted the President to have only defensive response power, and not offensive response power, seems pure speculation.

Instead, the book insists that the proper framing of the question is this: because the executive power traditionally included the power to respond offensively to attacks, that power goes to the President unless it is assigned exclusively to Congress; the only clause that seems capable of doing this is the declare-war clause, so the question is whether an offensive response to an attack “declares” war in eighteenth-century terms. I think the evidence that it did is very thin, and the evidence that it did not is material, although not as strong as I’d like it to be. But I’ll be happy to say the book has succeeded if I’ve convinced you this is the right way to frame it.
Opinio Juris Symposium: A Clarification on the President's Power to Respond to Attacks
Professor Lederman asks in a comment to Professor Kent’s post if we could clarify our disagreement on the President's power to respond to attacks. Briefly, here is how I understand it. I think both of us agree:

(1) That Congress has the ultimate control over the U.S. response to an attack, in that it can limit the response by statute, or simply refuse to approve funding for certain kinds of responses; and

(2) That in the absence of statutory approval the President can “repel sudden attacks” (as Madison said at the Convention) in a defensive manner, at least until Congress acts.

The disagreement is whether the President can direct offensive measures against the attacker. I am not sure what the line between offensive and defensive response would be, but I assume, for example, that attacking the enemy homeland is an offensive response. My view is that the President can make offensive responses, so I don’t need to draw that line; I will leave to Andrew where he would draw it (and how).

Professor Lederman also asks if there are any modern examples where this would have mattered. I think the answer is no, although I may be missing one. In my view, the President’s power of offensive response is triggered only where another entity attacks the U.S. or U.S. forces in such a way to initiate a state of war. (In other words, an isolated engagement, or alleged engagement, is not enough, nor is an attack on an ally). I think one justification offered for the 1989 invasion of Panama was an attack on U.S. troops in Panama, but I am not clear enough on the facts to know if this should count. The only clear modern example that comes to mind is September 11, and that depends on whether one thinks there can be war with a non-state entity like al-Qaeda. Assuming there can be, my view would give the President independent constitutional power to attack al-Qaeda forces in response, as long as he did not create a state of war with any other nation — for example, he could attack al-Qaeda bases in Pakistan with Pakistan's permission. (Attacking Afghanistan would require congressional approval though). Of course, the President got approval to respond against al-Qaeda, so the point was not raised.
Opinio Juris Symposium: Can President Obama Attack Pakistan?
I have some more detailed thoughts on the postings by Professors Kent, Flaherty, and Ramsey but I did want to note one news item today that is actually relevant to the discussion between Professors Ramsey and Kent about the President's ability to use military force to respond to attacks.

In a major national security address, presidential candidate Barack Obama called for the U.S. government to use military force against terrorists inside Pakistan if the current Pakistani government refuses to act to suppress them.

Would such attacks, without Pakistan's permission, be legal under U.S. constitutional law?

As Professor Ramsey points out, this would probably be authorized by the September 11 Resolution, which allows military force against Al Qaeda. But if the September 11 Resolution did not apply for some reason (e.g. it is repealed), he suggests no responsive attack is permitted without Pakistan's permission. (And I assume Professor Kent's view is that even with Pakistan's permission, no responsive attack is legal.)

Why would Pakistan's permission make a difference though? Is it because of the President's constitutional duty to "Take Care" of the "Laws", which includes international law? But the customary international law governing the use of military force is notoriously murky and it seems like the President could claim that international law allows this sort of attack as preemptive self-defense, even without Pakistan's permission. We can stretch the hypo beyond Pakistan and imagine a President Obama invading Darfur to stop the genocide, etc. etc. Would the President's claim that stopping genocide allows the use of military force and the violation of another country sovereignty be acceptable?

Based on Professor Ramsey's analysis in Chapter 18 of his book, the President cannot violate international law, but he is given wide discretion to interpret it. And courts are bound, in his view, to defer to executive interpretations absent contrary action by Congress. This seems right to me, but I wonder whether this leaves any room for judicial interpretations of international law in defiance of the executive's interpretations?
Opinio Juris Symposium: Are Non-Self-Executing Treaties Unconstitutional?
I would like to push the conversation about Mike Ramsey’s new book to a slightly different topic. What does the Constitution’s text tell us about the status of treaties in the domestic U.S. legal system? As many of our readers know, Article VI of the U.S. Constitution makes treaties the “supreme law of the land,” but conventional wisdom has been that the text has not resolved a variety of questions over the proper status of treaties. I think Professor Ramsey successfully defeats this conventional wisdom, but I am not sure he has completely resolved lingering questions about the status of treaties?

For instance, does Article VI mean that all treaties are “self-executing” in the sense that they bind the President and the executive branch and create enforceable judicial remedies enforceable by private actions in U.S. courts? Does Article VI also mean that treaties bind Congress so that Congress cannot pass legislation in violation of an Article II treaty? Does Article VI also tell us whether a treaty can trump the U.S. Constitution?

Staying true to his method, Professor Ramsey finds a textual answer to all of these questions. Article VI’s reference to treaties as “supreme law”, he suggests, should be understood to give treaties the same domestic legal status as federal statutes. For this reason, treaties are self-executing, at least in the same sense as federal statutes are self-executing. Congress can override treaties with subsequent legislation (e.g. the last in time rule). Moreover, treaties that are inconsistent with the Constitution are, like federal statutes, unconstitutional and unenforceable. And the President is bound by treaties, at least as much as he is bound by federal statutes.

All of these answers are consistent with existing doctrine and they provide a wonderfully clear and straightforward textual basis in favor of existing doctrine. But there is one area in which Professor Ramsey has departed somewhat from conventional doctrine.
Opinio Juris Symposium: Original Meaning Comes Up Short in Foreign Relations Law
I’ll join the chorus praising Michael Ramsey’s work, both the book The Constitution’s Text in Foreign Affairs and his scholarship over the course of more than a decade. Mike’s is an important and distinctive voice in the foreign relations law community. It is refreshingly agenda-free. As Martin Flaherty points out, his conclusions don’t line up neatly along the ideological divide. One might expect the textualist focus of his work to incline him to more revisionist results, and I’m sure the revisionists would like it to be so. Sometimes they do, but on other important issues, he parts ways. To add just one example, Mike sees a historical-textualist basis for Missouri v. Holland. So there is a call-it-like-he-sees it credibility to this work. In the relative land-grab days of foreign relations law, this book stakes a strong claim to a lot of turf. It will be the starting point for future originalist-oriented research in the field.

That said, this all looks like an exercise in scripturalism to me. As a structuralist/functionalist on these issues, someone who thinks recent history far more relevant than the ancient, I feel rather like a Crusader commenting on the Koran. Although the book declaims any position on method and the extent to which text and historical meanings should frame contemporary debates, it’s hard to avoid the implication that these sources should figure more prominently to the extent they “provide a fairly complete basic framework for foreign affairs law.” If it is fairly complete, then it can work as an exclusive methodology, insofar as you don’t have to look for answers anywhere else.

But I think the book ultimately demonstrates that you can’t find all the answers in original meaning. If Mike can’t find the answer, then no one can, and we’re left with the question of what other method should fill the gaps.

In the context of foreign relations federalism, for example, Mike isn’t in a position to play the text straight on a dormant federal power; he concedes that powers beyond those specified in article 1, section 10 are barred to the states. How to tell which ones fly and which don’t? Here he turns to Federalist No. 32 and Hamilton’s observation that states would be denied concurrent power where it would “totally contradictory and repugnant” to the exercise of federal power. Leave aside the use of the ancillary source by way of a rule of decision – and I agree with Martin’s point that Mike exaggerates historical certitude in the face of textual ambiguity – but how do we determine when the exercise of a state power will qualify as such?


Opinio Juris Symposium: The Textualist Case for Congressional Control Over Responses to Military Attacks
One of my major purposes in discussing Professor Ramsey’s treatment of the scope of the president’s power to respond to attacks was to suggest that here, on this topic, his book may not meet its goal of giving dispositive interpretive weight to the written constitutional text as understood by Americans at the time of ratification. To the extent, then, that my initial post savored of “abstract intent-oriented reasoning” rather than textualist originalism, I failed to explain myself clearly enough.

As I said in my earlier post, I find Professor Ramsey’s analysis of the President’s power to respond to attacks too focused on the Declare War Clause. Because he interprets “declare” to mean only that Congress may begin war, responding to already existing warfare against the United States is not a declaration and therefore not a congressional prerogative. His “executive power” default rule means this power must be wholly the President’s. It can be exercised offensively and “without limitation,” Professor Ramsey suggests, unless Congress can pass a restrictive statute by a veto-proof margin.

But, as I suggested before, this analysis downplays other relevant clauses of the Constitution. In reading the Constitution on this issue, my background assumption is that a nation attacked has a full spectrum of possible responses, ranging from doing nothing to using all of its resources to obliterate the enemy’s homeland. Deciding whether and how to respond is a policy question of substantial moment. In the eighteenth century, there were several common ways of responding to attacks and other serious provocations by another country, each of which would be located somewhere between the poles of my spectrum of potential responses. A nation could strike back by issuing licenses to private seamen to attack the aggressor’s shipping. This is the Marque and Reprisal Clause, found in Congress’s Article I. A nation could impose an embargo or other retaliatory commercial sanctions. This is Congress’s Foreign Commerce Clause. A nation could denounce treaties of amity, alliance or commerce previously contracted with the aggressor. This, as I suggested in a recent article, is Congress’s power under the Law of Nations Clause (giving power “to define and punish . . . offences against the law of nations”). A nation could refuse admittance to, or expel once admitted, individual subjects of the aggressor nation. This is Congress’s power over naturalization and, as Necessary and Proper to implementing that, immigration and deportation. A nation could authorize its public warships to seize enemy warships or private shipping. This is Congress’s power to make rules concerning “captures.” If the enemy’s conduct violated international law, Congress could use Article I powers (under the Law of Nations and Inferior Tribunals Clauses) to institute criminal prosecutions against captured enemies.

These are all powers to calibrate and moderate, for policy reasons, the United States’ response to provocations. These powers have both positive and negative components. They authorize responsive measures; but they are also powers to decide not to respond to hostilities by full-scale warfare. These powers are all given to Congress. (With one exception: another common way a nation might retaliate short of warfare – by expelling the aggressor’s diplomats – is pretty clearly a presidential power, either implied from the duty/power to receive foreign ministers or found, though Professor’s Ramsey’s reasoning, in the Vesting Clause.)

Congress’s prerogative to make the policy decisions about how to measure and target the nation’s responses to hostilities is, I believe, clearly found in the Constitution’s text. Under Professor Ramsey’s theory, these cannot then be within the “executive power” of the President. Putting aside that textual theory and relying just on common sense, it is not hard to see why this must be true. These congressional powers would be substantially or wholly vitiated if the President could decide on his own that the proper response to an attack was full-scale offensive warfare. It is not an answer to say that Congress could always limit the President’s discretion by statute and therefore protect its responsive powers. Because he is continually in office (while Congress has lengthy recesses), and is a single and hence fast decision-maker, the President could react faster than Congress to an emerging crisis and outrun Congress’s ability to pass a restrictive statute by a veto-proof margin.

Adding up all of these congressional powers to calibrate hostilities, joining them to the Declare War Clause, and giving them the fulsome scope suggested by the Necessary and Proper Clause, we have, I believe, a nearly complete textual vesting in Congress of the power to decide how to respond to enemy attacks. Several parts of the Constitution – the Commander-in-Chief Clause; the duties to protect implied by President’s oath, the Take Care Clause and the nature of the office; and the fact that the Constitution contemplates Congress but not the President taking recesses – suggest to me that the President has textual authority to repel hostilities launched against the United States. And when the speed of events and a congressional recess mean that Congress cannot be consulted in time, the President’s would have authority to move beyond the strictly defensive and take effective offensive actions designed to preempt further enemy attacks likely to occur in the near future. But the nearly-full spectrum of responsive powers given to Congress, and the fact that the Constitution contemplates the President convening special sessions of Congress, suggest to me that the President has a constitutional duty to convene Congress and take its direction as soon as possible. Until that time, the President has a constitutional duty (Take Care Clause) to protect the nation in a way that preserves as much as possible the constitutional discretion of Congress to decide how to calibrate the nation’s response to attack.

Would President Obama, if he were to take office in 2009, have constitutional authority – independent of any authorizing statute like the post-9/11 AUMF – to attack al Qaeda forces holed up in Pakistan, with or without the consent of the Pakistani government?
Opinio Juris Symposium: The Temptation of a Coherent Constitution
I am happy that any disagreement Professor Ramsey and I have regarding history is more a matter of degree than of kind. That said, the matter of degree may well be greater than even he acknowledges. To that extent, I believe he may oversell a number of the ostensibly textual points he makes in his work.

The agreement in kind relates to the potential ambiguity of historical sources. It is indeed refreshing – and doubtless a source of Professor Ramsey’s own substantial historical research – for a legal scholar to concede that history may frequently produce answers every bit as contradictory, unclear, and messy as other sources of constitutional interpretation. I further agree that the use of “Laws” in Article II, section 3, and the use of “Laws” more generally in the Constitution, resisted a public consensus in any individual case, much less anything approaching a consensus across the board. Conversely, I myself concede that in certain instances history can yield a sufficiently clear, general understanding at the time a particular text was ratified. Here as well, Professor Ramsey’s reliance on the “Declare War” Clause hits the mark. In line with Treanor and many others, yet contrary to Yoo, I too read the relevant sources as confirming the view that the Clause means that Congress must initiate hostilities.

Yet there remains the difference in degree. Decades of poking around in these materials convince me that cases in which a dominant or prevailing public understanding emerges as applied to modern controversies are few and far between – especially in the context of separation of powers. I do not necessarily go as far as Justice Jackson in Youngstown, who famously declared that what the Founders thought about specific separation of powers issues are “as enigmatic as the dreams Joseph was called upon to interpret for Pharaoh,” that is, never clear. But I tend to come close.

At the risk of extending an overlong debate, a case in point is Professor Ramsey’s central reliance on the term “executive power.” His basic contention remains Hamiltonian, or at least consistent with what Hamilton argued briefly in passing. “Executive power,” the argument goes, included a general conception of foreign affairs power as generally understood in the 18th century. It then follows elegantly that the Constitution’s text becomes marvelously coherent. Unless otherwise specified, the default position in foreign affairs controversies is that executive assertions prevail. To his credit, Professor Ramsey tempers this key assertion with a generous view of instances in which the Constitution brings in the other branches, especially the Senate. The problem with all this is simply that beyond its core meaning of “implementing laws,” executive power commanded no general agreement. To the contrary, almost no one even made the specific argument that the term included foreign affairs powers. Sadly, forests have been felled and global warming advanced by detailed debates between myself and Curtis Bradley on one side, and Professor Ramsey and Saikrishna Prakash on the other. My point here is less about who is right or wrong. It is, rather, that I believe the exchange at a minimum indicates that the certainty of history does not go anywhere as far as Professor Ramsey generally assumes.

To this I would add a more nearly textual point, though one rooted in historical reality. Professor Ramsey’s constitutional approach may flirt too much with what Christopher Eisgruber refers to as the “aesthetic fallacy.” By this Eisgruber – in the spirit of Henry Monaghan, oddly enough – means the view that the Constitution is a wonderfully coherent document in which nearly all language and structure clearly relates to each other, and that if we just think about it hard enough, we too will appreciate its elegance and clarity. A historian, conversely, presupposes that this is a document chock full of compromises hammered out piecemeal by men with very different backgrounds, all of whom were sweating in wool clothing during a hot Philadelphia summer wanting to get home sooner or later. One would expect, in other words, that the Constitution would be filled with certain gaps, inconsistencies, and surprises notwithstanding a general elegance.

The allure of an aesthetically pleasing Constitution is seductive. It makes for a powerful theory, one reason why I think that Professor Ramsey’s book will be influential. The appeal of such a Constitution nonetheless leads interpreters astray. Nowhere is that more true than where the quest for textual coherence tends to eclipse the historical complexity that should give anyone pause before embracing global coherence in the first place.
Opinio Juris Symposium: Thoughts in Response to Professors Spiro and Ku
Thanks again for the excellent comments. Here I’ll take up those offered by Professors Spiro and Ku. I agree with Professor Spiro that historical textualism can only go so far in answering modern questions (assuming one wanted to use it that way), and that some contemporary perspective is inevitable. But I think it goes a lot further than he admits, and the Zschernig v. Miller example proves it. How much involvement should states be permitted to have in foreign affairs? That is surely a difficult policy question with many possible answers – and, perhaps as important, many possible ways of framing it. Historical textualism provides an approach, as I’ve laid out: states cannot do things that are specifically prohibited in Article I, Section 10 or by statute or treaty; at minimum, there is a very strong presumption that other things are permitted. (A literalist would say that all other things are permitted, but the Hamilton quote and others like it suggest that this goes beyond the way founding-era Americans understood the language, so I would not go that far.) Even the moderate Hamiltonian version, though, shows Zschernig to be plainly wrong. No amount of appeal to the dangers of the Cold War in the abstract can suggest that states administering their own probate laws in ways that have caused some minor diplomatic objections (but not enough to worry the State Department) is something that either (a) is totally contradictory to the federal exercise of foreign relations; or (b) could not easily be fixed by treaty or statute. The point of (and the payoff from) the appeal to original meaning here would not be that the framers addressed this very situation, but that the historical meaning of the Constitution’s text establishes a framework that places a very high burden on the federal government in a Zschernig-type situation – one that could not possibly have been met in Zschernig itself, and probably not in most other cases likely to arise.

Two other quick points. First, although Professor Spiro doubts that original meaning can provide much certainty in deciding modern debates, I’m quite skeptical that either of his alternatives (“functional criteria and more recent practice”) can do anywhere near as well. In foreign affairs federalism, for example, practice seems to consist of states taking increasingly important roles (as Professor Spiro has well documented) but also an array of Supreme Court cases pointing the other way (not just Zschernig, but Dames & Moore, Crosby v. NFTC, and AIA v. Garamendi). I really don’t know what to make of these competing trends. And “functional” (aka policy) considerations seem necessarily always in the eye of the beholder.

Second, it’s not clear to me that the use of historical meaning is an all-or-nothing proposition, as Professor Spiro seems to imply. Although I’m not necessarily advocating the approach, I could imagine someone saying that historical meaning can be a starting point or a presumption, subject to overriding functional or practice-based modifications. Thus one could see a role for the book’s project in modern debates, without denying the relevance of other considerations.

Professor Ku raises some interesting and somewhat related thoughts on self-executing treaties. I tend to agree with his policy preference for non-self-executing treaties, mostly for the reasons he states. But I don’t think that makes them any more defensible under the text’s historical meaning. A short version of the history, as I see it, goes like this: the Framers dramatically overreacted to two foreign policy crises of the 1780s under the Articles of Confederation. First, under the Articles not only were treaties not self-executing, but they could not be implemented by federal legislation. Implementation depended on the states, which were totally irresponsible, especially (but not only) in the case of the treaty rights of British creditors. Second, the attempt by a majority of states to make a treaty with Spain that traded claims to the Mississippi River for concessions elsewhere enraged the minority with Mississippi interests. The result was that the Framers created what seems a fairly odd treaty regime, at least for a nation that wants an active foreign policy: they made treaties very hard to approve; and once approved, made their implementation inflexible and legalistic. There’s a lot not to like in the framers’ model, but I think it quite clear (with apologies to Professors Flaherty and Spiro) that this is the model they chose.

On the self-execution point, for example, Article VI flatly says that “all” treaties “shall be” the supreme law of the land. Non-self-execution manifestly requires the Senate, or the President, or the courts, to say that, nonetheless, some treaties shall not be the supreme law of the land. Because I am not a literalist, I am open to historical evidence showing that, despite the text’s apparent clarity, this is not the full story as to how founding-era Americans understood it. But there isn’t any such history, and in fact what history there is confirms the apparent meaning. (Let me acknowledge in passing my great debt to Professor Carlos Vazquez, who made these points fully and forcefully before me). While I share Professor Ku’s discomfort, I think we have to recognize that sometimes the framers made mistakes (and in this case it is perfectly understandable how they came out where they did).

The modern question is what to do about it. What we have done, in this case, is to evolve a practice that evades both of the framers’ key commands: that treaties receive supermajority approval (by allowing congressional-executive agreements), and that treaties necessarily be part of the law of the land (by permitting the Senate/President/courts to say that sometimes they are not). Perhaps we can regard these developments as de facto constitutional amendments, or else just the practice and policy that Professor Spiro prefers.

I think this story is interesting in itself, even if one resists using the historical meaning to determine modern meaning. For that reason alone, I think Professor Spiro is too quick to dismiss the project – surely it’s worth knowing where we started, even if we have come out somewhere else? And one might think (though again I stress that I am only suggesting) that self-execution’s (and treaty supermajority’s) root in and over-reaction to particular problems of the eighteenth-century supports a relaxation of the framers’ command, whereas in foreign policy federalism the lack of any compelling policy imperatives or unbroken practice supports sticking with the framers’ design. In any event, to make arguments like these, the first step is to figure out the text’s historical meaning. For now, that’s all I’m trying to do.
Opinio Juris Symposium: Additional Thoughts on the President's Military Response Power
Professor Kent’s additional comments helpfully clarify his textual argument on the power to respond to attacks. I now see (I think) that he is relying on a negative implication: the President must not have this power because it would vitiate important powers of Congress. I do think this is a more promising approach than trying to jam the response power into the declare-war clause (which I think is about launching attacks, not about responding to them). But I still don’t see where, specifically, Congress’ power comes from. Congress does have a broad array of military powers, but none seems easily to encompass the military response power (especially if it’s agreed that the declare-war clause does not). Ordering U.S. forces to counterattack against an aggressor is not regulating the armed forces, or raising armies, or issuing letters of marque, or making rules on captures. And to rely on the necessary-and-proper clause, there needs to be a relevant power of Congress (or of another branch) in the first place.

I would say instead that the President has some powers that can be exercised in response to attack, including diplomatic measures (as Professor Kent agrees)
