The families of the German victims of the tragic MH 17 incident have reportedly decided to claim compensation from Ukraine. Although the details and the legal foundations of the claim have not been disclosed, what we know is that Professor Elmar Giemulla, representing the claimants, intends to bring this case before the European Court of Human Rights [ECtHR]. According to Professor Giemulla, “[e]ach state is responsible for the security of its air space […] If it is not able to [protect its air space] temporarily, it must close its air space. As that did not happen, Ukraine is liable for the damage.”
At the present stage many specific details are unclear, such as the admissibility of the claim or its articulation in the language of human rights law instead of international air law. There is, however, one apparently clear choice of legal strategy based on Professor Giemulla’s announcement: the identification of the internationally wrongful act in question, namely, Ukraine’s omission to close its airspace and to permit continued traffic.
Ukraine was indeed required to “take all practicable measures” to prevent offenses against the safety of international aviation under the 1971 Montreal Convention for the Suppression of Unlawful Acts against the Safety of Civil Aviation (Article 10). Given its sovereignty over its airspace, the customary duty to take reasonable steps to protect aliens within its territory required the same from Ukraine, just as its human rights obligations did under the European Convention of Human Rights. In Ilaşcu v. Moldova and Russiathe ECtHR held that the State’s positive obligations do not cease to exist when de facto it is not able to control a part of its territory. Ukraine, to use the Court’s language, “must endeavour, with all the legal and diplomatic means available to it vis-à-vis foreign States and international organisations, to continue to guarantee the enjoyment of the rights and freedoms defined in the Convention”, even within the territory controlled by separatists (see para. 333 of Ilaşcu).
The legal basis of MH 17′s presence in Ukraine’s airspace was Article 1 of the 1944 International Air Services Transit Agreement, conferring the right on foreign aircraft engaged in scheduled international air services to fly across its territory (both Ukraine and Malaysia are parties to the Agreement). Closing the airspace would have been one of the “legal means” available for Ukraine under the same Article, given that the exercise of this privilege (the “first freedom of the air”) is subject to the specific approval of Ukrainian authorities in “areas of active hostilities”according to the same Article 1. Further, Article 9 of the 1944 Chicago Convention on International Civil Aviation provides that States may, “for reasons of military necessity or public safety”, restrict or prohibit foreign aircraft from using certain parts of their airspace. One important constraint is that such restriction “shall be of a reasonable extent and location so as not to interfere unnecessarily with air navigation.” In fact, Ukraine exercised this right before the MH 17 tragedy and closed its airspace up to flight level 320 (32 000 ft); MH 17 was flying at flight level 330.
The question whether Ukraine’s failure to completely close its airspace before the incident is in itself a breach of international law (may it be international air law, international human rights law or law of the treatment of aliens) is an intriguing one, yet the present post focuses on a second possible hurdle for this claim: the issue of causation (for more on air law aspects, see Professor Abeyratne’s article here) . Article 31 of the ILC Articles on the Responsibility of States for Internationally Wrongful Acts [ARSIWA] provides that the obligation to provide reparation is conditional upon a causal nexus between the internationally wrongful act and the damage. Did Ukraine’s decision to leave open its airspace above flight level 320 in the Dnipropetrovsk Flight Information Region cause the downing of MH 17? Read the rest of this entry…
