¹⁴³ ILC Commentary, supra note 19, at 181, ont. 8, n.410. In Payment of Various Serbian Loans Issued in France (Fr. v. Serb.), 1929 PCIJ (ser. A) Nos. 20/21, at 5 (July 12), the PCIJ dismissed Serbia’s economic “force majeure” plea and held that “the war itself, despite its grave economic consequences,” did not give rise to a necessity defense affecting Serbia’s legal obligations. Id. at 39-40. In Chinn (U.K. v. Belg.), 1934 PCIJ (ser. A/B) No. 63 at 65, 112-14 (Dec. 12), only Judge Dionisio Anzilotti, in his separate opinion, reached necessity, but he noted that Belgium probably did not itself mean to raise the defense and that, at any rate, it would have been rejected on the facts. Id, para. 7. See ILC Commentary, supra note 19, at 181, cmt. 8, n.410 (citing Chinn, supra). Finally, the commentary, id., cites French Co. of Venezuehn R.R. (Fr. v. Venez.), 10 R.I.A.A. 285 (Fr.-Venez. Mixed Claims Comm’n 1902), without comment. That award, in short, considered and rejected the classical conception of necessity; it offers no support for Article 25.

¹⁵⁴ Under Article 21 of the Articles on State Responsibility (self-defense), the “wrongfulness of an act of a State is precluded if the act constitutes a lawful measure of self-defence taken in conformity with the Charter of the United Nations.” The UN Charter did not exist at the time, and even if it had, it would be implausible to characterize Great Britain’s seal hunting as an armed attack. Under Article 23 (force majeure), the wrongfulness of an act may be precluded if it is attributable to “the occurrence of an irresistible force or of an unforeseen event, beyond the control of the State, making it materially impossible in the circumstances to perform the obligation.” Seizing the British vessels, which Russia ordered, did not, of course, lie beyond Russia’s control.

¹⁵⁶ Another arguable authority not cited in the ILC Commentary is the Faber case. Venezuelan Arbitrations of 1903, at 600 (Ralston, Jackson Harvey & Doyle, W. T. Sherman eds., 1904 Google Scholar). Yet neither Germany nor the arbitral umpire even framed the issue in terms of necessity. Only in dicta, after issuing his ruling, did the umpire mention necessity—and even then, only in passing and in the course of a more general digression into “the true source of natural law.” Id. at 626; see id. at 627-30.

The Second Report Addendum says that Spain’s memorial subsequently “dealt with issues of justification at some length” but, tellingly, “[w]ithout expressly referring to draft article 33.” Because of the ICJ’s lack of jurisdiction, “the claim was . . . neither formally pleaded nor adjudicated on the merits.” Second Report Addendum, supra note 42, para. 285.

¹⁷⁹ Cheng’s citation of national law might suggest the first, Cheng, supra note 49, at 69 n.3, but the sheer variety of national conceptions belies this possibility. Nor can necessity be characterized as “intrinsic to the idea of law and basic to all legal systems,” Schachter, supra note 178, at 50, for it is a comparatively recent development in national law. See Fletcher, supra note 170, at 774-75. Finally, the fourth and fifth conceptions in Schachter’s typology seem incongruous as applied to necessity in the context of a legal system (international law, in general, and the law of state responsibility, in particular) that chiefly governs states rather than human beings.

²²⁵ To adapt an example made famous by Ronald Dworkin, see Dworkin, Ronald, Law’s Empire 15–20 (1986)Google Scholar, Anglo-American law, like international law, adopts the general principle that no one should profit from his own wrong. Consequently, the New York Court of Appeals construed a statute of wills—which, interpreted literally, might have bequeathed an estate to the very man who had murdered the legator in order to ensure his inheritance—to conform to the general principle that a delictor may not benefit from his own delict and thereby avoided this absurd result. See Riggs v. Palmer, 22 N.E. 188 (N.Y. 1889). General principles play a comparable role in inter national law, and for this reason, among others, any formal or literal normative hierarchy in international law would likely be misguided. For a more detailed analysis and critique of the idea of a normative hierarchy in international law, see generally Caplan, supra note 223.

²⁴⁸ Not coincidentally, John Rawls excluded international law from his initial theory of justice. See Rawls, John, A Theory of Justice 7–8 (1971)Google Scholar. Even within a polity, Rawls later concluded, “The fact of a plurality of reasonable but incompatible comprehensive doctrines—the fact of reasonable pluralism—shows that, as used in [A Theory of Justice], the idea of a well-ordered society of justice as fairness is unrealistic.” Rawls, John, Political Liberalism, at xvii (1993)Google Scholar. Time and again, he stressed that “in modern democratic societies,” value pluralism “is not a mere historical condition that may soon pass away; it is a permanent feature of the public culture of democracy.” Id. at 36. A fortiori, it is a permanent feature of the “different cultures and traditions of thought” found within the figurative international community.

²⁶¹ It would be equally misguided to construe provisions of the Articles on State Responsibility other than Article 25 solely as decision rules. Countermeasures (part 3, chapter II of the Articles on State Responsibility), for example, establish, and presumably were intended to establish, principles that will influence state conduct—namely, the circumstances under which states may take countermeasures and the nature and scope of those measures. Chapter II does not deal only with the formal consequences of a violation in the event that an institution happens to be available to apply the Articles on State Responsibility as decision rules.

In contrast, force majeure (Art. 23), absent a lex specialis, is generally an excuse.

Because Article 52 of the ICSID Convention sharply limits the grounds for annulment, substantive analysis of the necessity plea has often been smuggled in under the strained rubric of an alleged excess of jurisdiction or failure of the tribunal to state reasons for its decision. See, e.g., Sempra Energy Int’l v. Argentina, ICSID Case No. ARB/02/16, Annulment (June 29, 2010) (characterizing a difference in interpretation of Article Xi of the U.S. Argentina Bit as manifest excess of powers).
