³ This version of interstitial law was first articulated by Lowe. As Lowe notes, interstitial rules are those ‘operating in the interstices between … primary norms’. In this sense, interstitial rules are secondary norms which modify primary norms, a distinction first articulated by Hart. For similar concepts in international law scholarship, see Arosemena on meta-rules, or Reinold and Zürn on secondary rules in international law, which they say are similar to ‘concepts such as legalization, procedural politics, interstitial lawmaking, etc’. See Lowe, V, ‘The politics of law-making: are the method and character of norm creation changing?’ in Byers, M (ed), The Role of Law in International Politics: Essays in International Relations and International Law (Oxford University Press, New York, NY, 2000) 213 Google Scholar; Hart, HLA, The Concept of Law (Oxford University Press, Oxford, 1961)Google Scholar; Arosemena, G, ‘Conflicts of rights in international human rights: A meta-rule analysis’ (2013) 2(1) Global Constitutionalism: Democracy, Human Rights and the Rule of Law 6 CrossRefGoogle Scholar; Reinold, T and Zürn, M, ‘“Rules about rules” and the endogenous dynamics of international law: Dissonance reduction as a mechanism of secondary rule-making’ (2014) 3(2) Global Constitutionalism: Democracy, Human Rights and the Rule of Law 247–8.CrossRefGoogle Scholar

¹⁵ The view that change can occur outside of treaty creation when the law is contested is accepted by the New Haven School of International Law, constructivist international relations and critical legal studies. This approach is in contrast to textualist approaches to international law, which see law as cemented in its written word, or legalist approaches, which assume that legal rules are reflective of reality. However, in some areas of international law, particularly in highly technical or one-off agreements, the possibility of changing legal meanings may be less relevant. This is, for example, a criticism that Gardiner notes of MacDougal and the New Haven School’s approach to treaty interpretation. In such cases, the laws have been written so as to avoid potential reinterpretation or to find it unnecessary.

¹⁷ The legal interpretations of international courts, such as the International Court of Justice, the International Criminal Court and the European Court of Justice, contribute to the process of legal interpretation, but do not have the same form of institutional authority compared to domestic courts.

²⁰ C Reus-Smit, The Politics of International Law (Cambridge University Press, Cambridge, 2003). Discourse and language have long been at the centre of the constructivist approach to international law: Onuf identified law as ‘commitment rules’ produced through the commissive speech-acts of political agents, and Kratochwil argued that the force of international law is dependent upon its place in communicative reasoning processes.

²⁴ The notion that customary international law is based in interpretation is contested, as public international law scholarship would instead describe this process in terms of the ‘ascertainment’ of customary law, see JL Kunz, ‘The Nature of Customary International Law’ (1953) American Journal of International Law 662–9.

²⁵ Lowe makes this point, arguing that the employment of interstitial law ‘does not depend upon it having normative force of the kind held by primary norms of international law’ as does the employment of customary international law. Lowe (n 3) 217.

³⁰ Blum and Heymann provide an overview of the legal and strategic implications of choosing the war paradigm versus the law enforcement paradigm, and the difficulties of choosing either. As they note, the individualised character of targeting in counterterrorism operations, particularly in the use of drone strikes against a specific target, is more reminiscent of a law enforcement approach. Likewise, they note that the killing of an individual based on ‘blame rather than status’, the difficulties in identification of a target, and the use of targeted killing outside of a clearly defined battlefield all suggest the war paradigm is not a perfect fit. Nonetheless, they find that the ‘continuous and systematic’ nature of the US targeted killing campaign, in particular, is better suited to the war paradigm, and that applying peacetime law to counterterrorism might erode those rules. See Blum and Heymann (n 5) 147–8, 156, 168.

The number of people killed by drone strikes during the Obama Administration was reported by Searle (n 70).

⁷² For example, in a May 2014 speech, President Obama stated that ‘what makes us exceptional is not our ability to flout international norms and the rule of law; it is our willingness to affirm them through our actions’. In addition, in a May 7 2013 speech, Harold Koh, previously the Legal Adviser of the US Department of State, stated ‘Under international law, [the Obama] administration has expressly recognized that US actions are constrained by the laws of war. So rather than treating this conflict as a Black Hole, this Administration has worked to translate the spirit of those laws and apply them to this new situation.’ Koh’s allusion to the ‘Black Hole’ legal approach could be read as a critique of the Bush Administration’s use of the ‘enemy combatant’ designation, and as an indication that the Obama administration is more willing than its predecessor to abide by the law.

⁷³ One exception might be the release of Guantánamo Bay detainees by the Obama Administration, which, as of February 2015, was at 88 total detainees released and, as of August 2015, included 52 potential others barring cooperation from the Pentagon. However, 532 detainees left Guantánamo before President Obama took office, suggesting that policy towards the detention centre has changed little beyond President Obama’s public declarations favouring the closure of the prison.

⁷⁸ As Corn notes, the ongoing application of self-defence suggests that the US is resorting to and executing the use of force under jus ad bellum principles, but, as jus in bello is meant to apply to the actual execution of combat operations, this has led to a conflation of these principles, as evidenced by US officials’ controversial use of jus ad bellum variants of necessity and proportionality in combat operations, see Corn (n 9) 58–9. Other counterarguments to the US approach to self-defence can be found in Boyle (n 9) 111–12; C Martin, ‘Going Medieval: Targeted Killing, Self-Defense and the Jus ad Bellum Regime’ in Finkelstein, Ohlin and Altman (n 55) 233; Brunstetter and Jimenez-Bacardi (n 13); R Christopher, ‘Imminence in Justified Targeted Killing’ in Finkelstein, Ohlin and Altman (n 55); Brooks (n 9); Brooks (n 2).

In a 2011 report, the ICRC stated that ‘In international armed conflict, all persons who are neither members of the armed forces of a party to the conflict nor participants in a levée en masse are entitled to protection against direct attack unless and for such time as they take a direct part in hostilities. Members of irregular armed forces (eg militia, volunteer corps, etc.) whose conduct is attributable to a state party to an armed conflict are considered part of its armed forces.’ … ‘In non-international armed conflict, all persons who are not members of state armed forces or organized armed groups of a party to the conflict are civilians and, therefore, entitled to protection against direct attack unless and for such time as they take a direct part in hostilities’, see 31st International Conference of the Red Cross and Red Crescent (n 52) 43. This guidance has met resistance as, for example, Anderson argued in the 2010 Congressional Hearing that a number of the provisions in the interpretive guidance are ‘over the edge’, and that he was ‘very surprised’ that the ICRC would put them out, given the fact that they could not command a majority of their own experts in that regard, see ‘Testimony of K Andersen’ in Subcommittee on National Security and Foreign Affairs of the Committee on Oversight and Government Reform (n 1) 57.

¹⁰² There are multiple other controversies revolving around the principle of distinction in US counterterrorism operations. For example, see the Stimson Report for problems stemming from definitions of combatancy and armed hostilities, Gen. JP Abizaid, and R Brooks (n 2). For overly permissive interpretations of distinction (as well as necessity and proportionality) see Brunstetter and Jimenez-Bacardi (n 13) 189; R Christopher (n 78) 257; and SA Shah, International Law and Drone Strikes in Pakistan: The Legal and Socio-political Aspects (Routledge, New York, NY, 2014) 24. For the contested basis of distinction as in either group membership or individual conduct, see Boyle (n 9); Brunstetter and Jimenez-Bacardi (n 13) 190; Martin (n 76) 149, 159–60; D Richemond-Barak, ‘Nonstate actors in Armed Conflicts: Issues of Distinction and Reciprocity’ in Banks (n 47) 115.

¹⁰⁵ President Obama has argued that the use of force in territories outside of Afghanistan (the initial purview of the AUMF) is justified by a state’s consent or the unable and unwilling criteria. Brooks (n 9) argues that this approach is ambiguous as to how a state’s consent will be evaluated, particularly when that consent appears to be covert as is arguably the case in Pakistan, and Boyle (n 9) sees the ‘unable and unwilling’ test as an erosion of external sovereignty. Issues of sovereignty in drone warfare are, according to Pejic really about the expanding application of the laws of war to wherever an adversary might be located, see Pejic (n 52) 34.
