(b) terms of Torture Convention
39It is convenient to turn next to the terms of the Torture Convention. Article 1 defines "torture" to mean the intentional infliction of severe pain or suffering, for identified purposes, "when such pain or suffering is inflicted by or at the instigation of or with the consent or acquiescence of a public official or other person acting in an official capacity." Article 2 requires that each State party take effective measures to "prevent acts of torture in any territory under its jurisdiction." Article 3 prohibits return ("refouler") of a person to another State where there are substantial grounds for believing the person would be in danger of torture. Articles 4 and 5 have been set out above. Articles 6-8 deal with obligations with respect to persons who may have committed an offence created in accordance with Art 4.
40There follow a series of Articles dealing with other obligations. Each of Arts 10 (obligation to educate and inform regarding the prohibition against torture), 11 (obligation to review rules for interrogation of those arrested), 12 (investigation of possible acts of torture) and 13 (establishing machinery for complaint) have a local territorial content. Article 10 does not make that explicit, but it is inherently improbable that a State was required to educate and inform law enforcement personnel of other States. Articles 11, 12 and 13 all refer to conduct arising "in any territory under its jurisdiction".
41Article 15 requires that a statement made as a result of torture shall not be invoked as evidence in any proceedings (except against a person accused of torture), which must refer to proceedings under the control of the forum State. Article 16 broadens the scope of the treaty beyond torture as defined: it requires each State party "to prevent in any territory under its jurisdiction other acts of cruel, inhuman or degrading treatment or punishment which do not amount to torture ...".
42These are all of the substantive Articles which appear in Part 1 of the Convention, in which Art 14 also appears. Although it is true that Art 14 does not contain a limitation to an act of torture committed within the territory under the jurisdiction of the forum State, it is clear that the right of redress which the State is required to ensure "in its legal system" is not directed to enforceable rights arising elsewhere. Part of the subject matter of Art 14 is that the right is, in the first instance, "to fair and adequate compensation". The Article does not identify by whom the compensation is payable: by inference, the party liable must be the individual who undertook the act of torture or the government on whose behalf the act was undertaken. Subject to consideration of Arts 4 and 5, if the intention were to require a State to provide for the enforcement of civil rights against other States, it would seem to be alone in having such an effect: see A Byrnes, "Civil Remedies for Torture Committed Abroad", in C Scott (ed), Torture as Tort, (2001, Hart Publishing) at 542.
43Turning to the operation of Art 5, to say that it establishes a universal criminal jurisdiction is either incorrect, or must be heavily qualified. First, a State is required to take measures necessary to establish its jurisdiction over "offences under its criminal law", being those required to be created by Art 4. Secondly, Art 5.1 operates only in the circumstances identified in pars (a)-(c). Paragraph (a) is localised to offences committed "in any territory under its jurisdiction" (disregarding ships and aircraft). Paragraph (b) requires a different sort of connection, namely that the alleged offender is a national of the home State. Paragraph (c) provides for an optional conferral of jurisdiction (if the forum State considers it appropriate) where the victim is a national of the forum State.
44Before noting the content of Art 5.2, it is necessary to determine the meaning of the words in the chapeau to Art 5.1, "the offences referred to in article 4". On one view, those offences are offences which that State is required to establish "under its criminal law." However, the conditions of jurisdiction referred to in pars (b) and (c) apply in their terms to offences which are not committed in the territory of the forum State. Those paragraphs would be otiose unless the offences referred to are offences either under the criminal law of the forum State or under analogous provisions enacted by another State. That broader meaning is also necessary in order to make sense of Art 5.2 which, by reference to extradition, appears to envisage an offence under a law of another State. (The language, referring "to any of the States mentioned in paragraph I of this article" is confusing: it is theoretically possible, but implausible, that Art 4 requires each State to make it an offence for a foreign government to commit acts of torture within its territory.)
45Again assuming the broader construction of Art 5, being a resident of the forum State is not a necessary condition for the establishment of jurisdiction over offences committed against the person, nor indeed is being a national of the forum State such a precondition (the obligation being discretionary in such a case). Further, a qualified universal criminal jurisdiction is more intrusive than a universal civil jurisdiction, in the sense that criminal proceedings against a State may result in a penalty rather than a liability to pay compensation, against that must be weighed the fact that the moving party in criminal prosecution is the State itself. Thus, to the extent that a universal criminal jurisdiction involves an infringement of the independence of the other State, control of such an infringement lies within the sovereign power of the home State. In an important sense, as has been frequently recognised in a domestic situation, Art 5 is consistent with maintaining within the executive (rather than conferring on private individuals), the power to control relations with foreign States.
46More important than these considerations, however, is the express provision in Art 5, acceptance of which is an integral element of entry into the Convention, of the universal criminal jurisdiction. That element is missing from Art 14 dealing with civil liability. The careful formulation of Art 5, in expansive terms, is incongruent with the proposed assumption of universal jurisdiction in Art 14.
47These considerations invite the conclusion that ratification of, or accession to, the Torture Convention, pursuant to Art 27, did not involve submission by each State party to the jurisdiction of the national courts of all other States parties with respect to claims for compensation arising from alleged acts of torture. That conclusion has support in a number of cases, which the applicants said should not be followed. Before turning to the case law, however, it is appropriate to address the other steps in the application of Arts 31 and 32.
48Further, it is convenient to address at this point the applicants' submission noted at 27 above that, in interpreting Art 14, "it is legitimate also to consider notorious State practice at the time of the adoption of the Convention Against Torture": written submissions, par 25. No authority was cited for this proposition and it is by no means clear what was intended. State practice, to which reference can be had under the Vienna Convention, Art 31, is limited to "subsequent practice in the application of the treaty" (a matter addressed below). It is State practice operating at the level of international relations, and not at the level of common domestic law. The applicants submitted that "it was well known that in many civil law jurisdictions victims of crimes can attach civil claims for compensation to criminal prosecutions". Rather than constituting "notorious State practice" this consideration is better treated as part of the context in which the treaty negotiations took place.
49In support of this contention, the applicants sought assistance from the concurring judgment of Breyer J in Sosa v Alvarez-Machain, 542 US 692 (2004) at 761-763. Sosa involved a claim under the Alien Tort Statute (USA). The question was whether that statute allowed a citizen of one foreign country to sue another for arbitrary arrest, which occurred in the foreign country, in a US court. The Supreme Court held that such a claim fell within the Alien Tort Statute only if permitted by international law. The conclusion of the court that it did not, in which Breyer J joined, did not assist the applicants. However, the applicants relied upon the following consideration dealing with international comity at 762-3. Noting that international law demonstrated procedural agreement that universal criminal jurisdiction extended to torture, Breyer J continued:
'That consensus concerns criminal jurisdiction, but consensus as to universal criminal jurisdiction itself suggests that universal tort jurisdiction would be no more threatening. ... That is because the criminal courts of many nations combine civil and criminal proceedings, allowing those injured by criminal conduct to be represented, and to recover damages, in the criminal proceeding itself. ... Thus, universal criminal jurisdiction necessarily contemplates a significant degree of civil tort recovery as well.'"
50Having taken these matters into account, Breyer J nevertheless found no procedural consensus "supporting the exercise of jurisdiction in these cases": at 763. However, for the applicants' purposes, namely the proper construction of Art 14, the relevance of domestic procedure in civil law countries should find reflection in the terms of the treaty, or at least in the treaty negotiations. There is no express reflection of this consideration in the language of the Torture Convention and the separate treatment of criminal and civil jurisdictions appears to be inconsistent with it being given significant weight. Nor did the applicants refer to any evidence of this consideration being dealt with in the course of treaty negotiations.
