A Legal Mirage: State Responsibility for Non-State Actor Interference with Space Systems
Published online by Cambridge University Press: 23 August 2018
Abstract
Outer space is becoming a more accessible and less expensive domain in which to operate. Consequently, growing numbers of state and non-state actors (NSAs) are operating in, to, and through space. At the same time, instances of space-based and ground-based interference with space systems are also increasing, disrupting crucial space-supported services and applications relied on by millions, with great financial and operational costs. The increased participation of NSAs in space activities raises particular concerns, especially the threat of intentional interference with space systems by nefarious actors like terrorist organizations. It also requires consideration of whether states bear responsibility and/or liability for the acts of NSAs with a nexus to those states. At first glance, it is tempting to conclude that one or more normative legal regimes would apply. The potential regimes include international space law, international telecommunications law, and the law of state responsibility. On further examination, however, when it comes to interference, there appears to be no effective legal mechanism to hold states accountable for NSA interference with space systems, which can be exploited by NSAs and challenge efforts by states to enforce “good” behaviour.
Résumé
L’espace devient plus accessible et les opérations extra-atmosphériques moins coûteuses. Par conséquent, un nombre croissant d’acteurs étatiques et non-étatiques opèrent dans ce domaine. Parallèlement, les ingérences spatiales et terrestres dans le fonctionnement de systèmes spatiaux se multiplient, perturbant les services et applications spatiaux essentiels sur lesquels comptent des millions de personnes et occasionnant des coûts financiers et opérationnels considérables. La participation accrue d’acteurs non-étatiques (ANE) aux activités spatiales soulève des préoccupations particulières, notamment la menace d’ingérence intentionnelle dans le fonctionnement de systèmes spatiaux par des acteurs néfastes tels des groupes terroristes. Elle pose également la question à savoir si les États portent une responsabilité quelconque pour les actes des ANE ayant un lien avec ces États. À première vue, il semblerait que plusieurs régimes juridiques internationaux s’appliqueraient à cette question, y-inclus le droit international de l’espace, le droit international des télécommunications et le régime de la responsabilité étatique. Cependant, un examen plus minutieux révèle qu’il ne semble pas y avoir de mécanisme juridique efficace pour imposer une responsabilité quelconque aux États pour les éventuelles ingérences des ANE dans le fonctionnement de systèmes spatiaux. Cette lacune pourrait être exploitée par les ANE et remettre en cause les efforts des États pour faire respecter les “bons” comportements dans le domaine extra-atmosphérique.

21 The first Gulf War is considered to be the first space war because Operation Desert Storm saw operational militaries become more dependent on space technologies to conduct operations in multiple domains.

24 Civilian uses of satellites include support to the functioning of financial and economic systems, the provision of telephone and television services, which provide instantaneous communications via the Internet, supports for the transmission of financial transaction data, the coordination of air traffic control, and the provision of “just-in-time” delivery of goods and the operation of cell phones.

25 At the beginning of the space age, the concept of dual use was essentially irrelevant because national space programs were largely controlled and led by the military, while civilian agencies were largely in a supporting role. However, over time, commercial space actors began operating space systems, which supported civilian and military applications.

33 Martin, supra note 10. E.g., cellular phones used for command and control operate using applications based on satellite communications (SATCOM), and the Internet is used to communicate and obtain information for planning purposes, such as obtaining imagery of specific locations from remote sensing data, which can be used to perpetrate attacks or other disruptions.
34 Light small satellites include mini-satellites (500 kilograms), micro-satellites (10–100 kilograms), and nano-satellites (1–10 kilograms), while pico-satellites (0.1–1 kilograms) and femto-satellites (10–100 grams) are in development. These satellites could be used to conduct space-based interference and would be much less expensive to launch due to their small weight.

42 It should be noted that jamming could be endorsed as an appropriate measure under Article 41 of the United Nations Charter; otherwise, it is generally considered to be interference. Jamming may be permitted where the United Nations (UN) Security Council calls upon member states to interrupt “postal, telegraphic, radio or other means of communication” in response to a threat to peace, a breach of the peace or aggression.

43 Housen-Couriel, supra note 13 at 434, 437, 440. Space systems are vulnerable to two main threats: non-kinetic (which can include electromagnetic interference or cyber-enabled interference) or kinetic (the effect of physically interfering, damaging, or destroying another satellite with another object either in orbit or launched from the ground for that purpose — e.g., direct assent anti-satellite weapons). This “dual threat” is amplified by cyber interference as satellites, the transmissions, and their associated ground stations are connected, commanded, and controlled using cyber platforms. However, cyber interference is outside the scope of this article. Lewis & Livingstone, supra note 34.

49 More recently, interference by cyber means has risen, with hackers gaining full functional control of the National Aeronautics and Space Administration (NASA) computers in 2011. This particular hacking incident resulted in the hackers getting full system access, which would have allowed them to “modify, copy or delete sensitive files,” which could have affected the International Space Station. In addition, between 2010 and 2011, NASA suffered 5,408 computer security incidents. Hacks to NASA systems range from those perpetrated by individuals testing their hacking skills, to organized criminal organizations looking for profit, to intrusions that may be sponsored by foreign intelligence services. “Hackers Had ‘Full Functional Control’ of NASA Computers,” British Broadcasting Corporation (8 March 2012), online: <http://www.bbc.com/news/technology-17231695>.

50 It is notable that where non-kinetic interference renders a satellite uncontrollable, that satellite could cause space debris as a second- or third-order effect if it collides with other debris or another satellite.

55 Geostationary orbit is an orbit at an altitude of 35,786 kilometres above the equator, where satellites travel at the same rate as the Earth rotates. Satellites in geostationary orbit are typically used for television and radio broadcasting as they allow real-time data transfer over a wide geographic area. They are also used for military and commercial communications. Harrison et al, supra note 2 at 18; Wright, Grego & Gronlund, supra note 26 at 13, 43.

66 It should be noted that under art 2(4) of the UN Charter, interference with satellite signals would not generally amount to a threat of force or a use of force against the territorial integrity or political independence of a state. However, depending on the effects of space-based or ground-based interference and the type of system affected, it may be considered to rise to the level of a threat of force, use of force or armed attack, and, therefore, the law relating to the use of force (jus ad bellum) or international humanitarian law (jus in bello) could apply depending on the situation. Mountin, supra note 5 at 108, 111–12.
67 A mega-constellation is a collection of related satellites, usually in low Earth orbit (LEO) operating to provide increased coverage and resilience for a particular satellite service. An example of a mega-constellation is OneWeb, which is planning a constellation of 648 satellites in LEO to provide global broadband communications services. Other proposed mega-constellations are considering using 1,400 and 3,000 satellites.

68 Orbital space debris can occur when a piece of space debris is in orbit itself and strikes another space asset or piece of debris, which is called a conjunction. Space debris can have catastrophic effects if it hits a functioning satellite, not only in the first instance by disabling, degrading, or destroying the satellite but also in then producing pieces of debris that, due to the Kessler effect, result in the propagation of more and more space debris as secondary and tertiary effects. Wright, Grego & Gronlund, supra note 26 at 136. NASA tracks approximately 500,000 pieces of space debris, in addition to millions of pieces that are too small to track, which are a threat to space assets, including the International Space Station.

96 Dembling, supra note 95 at 34–35. In utilizing space for social, economic, and national security activities, it is generally accepted that the risk of damage or injury should not be passed from “the creator of the risk to the public at large,” except in certain circumstances where the launching state reaps the benefits; however, damages in that context would be dealt with under domestic law via a claim against a government.

98 The construct of tracing responsibility to the supervising state was codified during the creation of the space age as a compromise between the United States, which favoured the unhampered use of space by private entities, and the Soviet Union, which advocated for a prohibition on private space activities and entities in space.

99 Responsibility can also flow under international law for lawful acts, which is normally the case with high risk, very dangerous activities, as is the case with space activities. Krystyna Wiewiorowska, “Some Problems of State Responsibility in Outer Space Law” (1979) 7:1 J Space L 23 at 32.

101 Crawford, Pellet & Olleson, supra note 36 at 904. Some examples include the Convention on Damage Caused by Foreign Aircraft to Third Parties on the Surface, which indicates that “any person who suffers damage on the surface shall, upon proof only that damage was caused by an aircraft in flight or by any person or thing falling therefrom, be entitled to compensation.” Convention on Damage Caused by Foreign Aircraft to Third Parties on the Surface, 7 October 1952, 310 UNTS 182 (entered into force 4 February 1958). A similar principle has been applied to atomic energy, which utilizes similar absolute liability regimes, including the Convention on Third Party Liability in the Field of Nuclear Energy, 29 July 1960, 956 UNTS 251 (entered into force 1 April 1968), and the Convention on the Liability of Operators of Nuclear Ships, 25 May 1962, 57 AJIL 268 [Nuclear Ships Convention]. Art II of the Nuclear Ships Convention provides that “[t]he operator of a nuclear ship shall be absolutely liable for any nuclear damage upon proof that such damage has been caused by a nuclear incident involving the nuclear fuel of, or radioactive products or waste produced in, such ship.” International Convention on Civil Liability for Nuclear Damage, 21 May 1963, 1063 UNTS 265 (entered into force 12 November 1977).
102 Dembling, supra note 95 at 34. Absolute liability is contrasted with “fault-based liability,” which is “liability based on some degree of blameworthiness.” Black’s Law Dictionary, 9th ed, sub verbo “fault-based liability.” “Fault” is defined as “an error or defect of judgement or of conduct; any deviation from prudence or duty resulting from inattention, incapacity, perversity, bad faith, or mismanagement. Under the civil law, “fault” is “the intentional or negligent failure to maintain some standard of conduct when that failure results in harm to another person.” Black’s Law Dictionary, 9th ed, sub verbo “fault.”

It should be noted that there are interpretation differences between the various translations of the text of the Liability Convention, in that the French and Spanish versions do not recognize a difference between “responsibility” and “liability.” Different translated versions also provide varying scopes of application for absolute liability.

200 The issue of lex specialis and how it applies to specialized bodies of law that interact has been much debated, particularly as it relates to the interaction of international humanitarian law (IHL) and international human rights law (IHRL).

These discussions reflect the view that potentially competing lex specialis should be read harmoniously to the greatest extent possible and that the analysis should be considered through the lens of the specialized body of law. Further consideration of the interaction of other areas of international law (i.e., IHL and IHRL) and how they may apply in the present scenarios is outside the scope of this article.

209 The interference event may provide a signature that can be used to determine the source. However, due to the nature of the space domain, especially where there is no damage to a space asset, it may not be suspicious due to the expansive and “distant nature of the domain” and the ability to masquerade assets as those operating for other purposes (i.e., military satellites pretending to be civilian or commercial). Zenko, supra note 48.
210 This was the case when Sputnik I was launched, as the United States did not launch a protest because they wanted to take advantage of the orbital overflight of other countries when they launched their own satellite shortly thereafter. Mountin, supra note 5 at 139.
