1 Article 12 of the 2004 United Nations Convention on Jurisdictional Immunities of States and Their Property (not yet in force) ostensibly provides an exception to state immunity in claims against an injuring state in the courts of a state where a conflict took place. However, according to the ILC commentary, ‘[i]t is also clear that cases of shooting or firing across a boundary or of spill-over across the border of shelling as a result of an armed conflict are excluded from the areas covered by article 12’.

For examples of the HCJ's emphasis on the justiciability of military activity during hostilities see Jaber Al-Bassiouni Ahmed v. Prime Minister, HCJ 9132/07 (27 January 2008), para. 20.

The position of the HCJ has long been that substantive justiciability is almost non-existent. This jurisprudence developed as a general matter, not confined to matters related to the Israeli–Palestinian conflict or to the occupied territories. Ressler v. Minister of Defense, PD 42(2), HCJ 910/86, 441, translated in (1992) 10 Selected Judgments Sup. Ct. Isr. 1, at 472–98.

25 The application of the international principle of command responsibility in domestic law in Malinki is a striking, and admittedly exceptional, example of a casual approach towards reliance on international law. The reliance on GC IV since the 1970s without admitting its application de jure is based on different considerations. See also Physicians for Human Rights v. Prime Minister of Israel (unpublished), HCJ 201/09 (19 January 2009).

27 That is a minimum requirement. Some domestic systems require that criminal prohibitions be expressly stipulated in domestic law.

31 The application of this standard by the US courts has been subject to criticism of being excessively strict. For present purposes, however, the question is not whether a particular interpretation of the Blackstone Three is meritorious but whether the very reference to the Blackstone Three is meritorious.

38 The case was concerned with the interpretation of the term ‘principles of humanity’ not in an international instrument but in a domestic one; however, a violation of the ‘principles of humanity’ under the relevant domestic law resembled the Martens clause, which speaks of the ‘laws of humanity, and the dictates of public conscience’ as well as the ‘elementary considerations of humanity’, which the International Court of Justice (ICJ), as well as the International Criminal Tribunal for the Former Yugoslavia and the International Criminal Tribunal for Rwanda (ICTR) have deemed on numerous occasions to constitute the foundation of rules of international humanitarian law Anonymous v.

41 The narrow interpretation of the term ‘principles of humanity’ could have been justified on a different ground, namely that at issue was a limitation on a basic human right, which should also be interpreted narrowly. However, the Court did not mention this explicitly, despite having mentioned that expropriation without compensation was a violation of a human right.

70 This phenomenon might be less pronounced in criminal proceedings based on universal jurisdiction; those, however, are the rare exception.

71 There may also be individuals temporarily present in the territory of the state, legally or otherwise. Conflicts of loyalties of courts may then exist, even if to a lesser extent, and depending on the circumstances (e.g. there may be greater commitment towards protection of persons allowed into the country legally than to those who have entered illegally).
