Regina v. Evans and Another and the Commissioner of Police for the Metropolis and Others Ex Parte Pinochet (On Appeal from a Divisional Court of the Queen's Bench Division) continued
|(back to preceding
But there was no tribunal or court to punish international crimes of torture. Local courts could take jurisdiction: see Demjanjuk (supra); Attorney-General of Israel v. Eichmann (1962) 36 I.L.R.S. But the objective was to ensure a gener al jurisdiction so that the torturer was not safe wherever he went. For example, in this case it is alleged that during the Pinochet regime torture was an official, although unacknowledged, weapon of government and that, when the regime was about to end, it passed legislation designed to afford an amnesty to those who had engaged in institutionalised torture. If these allegations are true, the fact that the local court had jurisdiction to deal with the international crime of torture was nothing to the p oint so long as the totalitarian regime remained in power: a totalitarian regime will not permit adjudication by its own courts on its own shortcomings. Hence the demand for some international machinery to repress state torture which is not dependent upo n the local courts where the torture was committed. In the event, over 110 states (including Chile, Spain and the United Kingdom) became state parties to the Torture Convention. But it is far from clear that none of them practised state torture. What w as needed therefore was an international system which could punish those who were guilty of torture and which did not permit the evasion of punishment by the torturer moving from one state to another. The Torture Convention was agreed not in order to cre ate an international crime which had not previously existed but to provide an international system under which the international criminal--the torturer -could find no safe haven. Burgers and Danelius (respectively the chairman of the United Nations Worki ng Group on the 1984 Torture Convention and the draftsmen of its first draft) say, at p. 131, that it was "an essential purpose [of the Convention] to ensure that a torturer does not escape the consequences of his act by going to another country.&quo t;
The Torture Convention
Article 1 of the Convention defines torture as the intentional infliction of severe pain and of suffering with a view to achieving a wide range of purposes "when such pain or suffering is inflicted by or at the instigation of or with the consent o r acquiesence of a public official or other person acting in an official capacity." Article 2(1) requires each state party to prohibit torture on territory within its own jurisdiction and Article 4 requires each state party to ensure that "all& quot; acts of torture are offences under its criminal law. Article 2(3) outlaws any defence of superior orders. Under Article 5(1) each state party has to establish its jurisdiction over torture (a) when committed within territory under its jurisdiction (b) when the alleged offender is a national of that state, and (c) in certain circumstances, when the victim is a national of that state. Under Article 5(2) a state party has to take jurisdiction over any alleged offender who is found within its territor y. Article 6 contains provisions for a state in whose territory an alleged torturer is found to detain him, inquire into the position and notify the states referred to in Article 5(1) and to indicate whether it intends to exercise jurisdiction. Under Ar ticle 7 the state in whose territory the alleged torturer is found shall, if he is not extradited to any of the states mentioned in Article 5(1), submit him to its authorities for the purpose of prosecution. Under Article 8(1) torture is to be treated as an extraditable offence and under Article 8(4) torture shall, for the purposes of extradition, be treated as having been committed not only in the place where it occurred but also in the state mentioned in Article 5(1).
Who is an "official" for the purposes of the Torture Convention?
The first question on the Convention is to decide whether acts done by a head of state are done by "a public official or a person acting in an official capacity" within the meaning of Article 1. The same question arises under section 134 of the Criminal Justice Act 1988. The answer to both questions must be the same. In his judgment at the first hearing (at pp. 1476G-1477E) Lord Slynn held that a head of state was neither a public official nor a person acting in an official capacity within the meaning of Article 1: he pointed out that there are a number of international conventions (for example the Yugoslav War Crimes Statute and the Rwanda War Crimes Statute) which refer specifically to heads of state when they intend to render them liabl e. Lord Lloyd apparently did not agree with Lord Slynn on this point since he thought that a head of state who was a torturer could be prosecuted in his own country, a view which could not be correct unless such head of state had conducted himself as a p ublic official or in an official capacity.
It became clear during the argument that both the Republic of Chile and Senator Pinochet accepted that the acts alleged against Senator Pinochet, if proved, were acts done by a public official or person acting in an official capacity within the meaning of Article 1. In my judgment these concessions were correctly made. Unless a head of state authorising or promoting torture is an official or acting in an official capacity within Article 1, then he would not be guilty of the international crime of tor ture even within his own state. That plainly cannot have been the intention. In my judgment it would run completely contrary to the intention of the Convention if there was anybody who could be exempt from guilt. The crucial question is not whether Sena tor Pinochet falls within the definition in Article 1: he plainly does. The question is whether, even so, he is procedurally immune from process. To my mind the fact that a head of state can be guilty of the crime casts little, if any, light on the ques tion whether he is immune from prosecution for that crime in a foreign state.
There was considerable argument before your Lordships concerning the extent of the jurisdiction to prosecute torturers conferred on states other than those mentioned in Article 5(1). I do not find it necessary to seek an answer to all the points raise d. It is enough that it is clear that in all circumstances, if the Article 5(1) states do not choose to seek extradition or to prosecute the offender, other states must do so. The purpose of the Convention was to introduce the principle aut dedere aut p unire--either you extradite or you punish: Burgers and Danelius p. 131. Throughout the negotiation of the Convention certain countries wished to make the exercise of jurisdiction under Article 5(2) dependent upon the state assuming jurisdiction having re fused extradition to an Article 5(1) state. However, at a session in 1984 all objections to the principle of aut dedere aut punire were withdrawn. "The inclusion of universal jurisdiction in the draft Convention was no longer opposed by any delegat ion": Working Group on the Draft Convention U.N. Doc. E/CN. 4/1984/72, para. 26. If there is no prosecution by, or extradition to, an Article 5(1) state, the state where the alleged offender is found (which will have already taken him into custody u nder Article 6) must exercise the jurisdiction under Article 5(2) by prosecuting him under Article 7(1).
I gather the following important points from the Torture Convention:
1) Torture within the meaning of the Convention can only be committed by "a public official or other person acting in an official capacity", but these words include a head of state. A single act of official torture is "torture" ; within the Convention;
2) Superior orders provide no defence;
3) If the states with the most obvious jurisdiction (the Article 5(1) states) do not seek to extradite, the state where the alleged torturer is found must prosecute or, apparently, extradite to another country, i.e. there is universal jurisdiction .
4) There is no express provision dealing with state immunity of heads of state, ambassadors or other officials.
5) Since Chile, Spain and the United Kingdom are all parties to the Convention, they are bound under treaty by its provisions whether or not such provisions would apply in the absence of treaty obligation. Chile ratified the Convention with effect from 30 October 1988 and the United Kingdom with effect from 8 December 1988.
This is the point around which most of the argument turned. It is of considerable general importance internationally since, if Senator Pinochet is not entitled to immunity in relation to the acts of torture alleged to have occurred after 29 September 1988, it will be the first time so far as counsel have discovered when a local domestic court has refused to afford immunity to a head of state or former head of state on the grounds that there can be no immunity against prosecution for certain internatio nal crimes.
Given the importance of the point, it is surprising how narrow is the area of dispute. There is general agreement between the parties as to the rules of statutory immunity and the rationale which underlies them. The issue is whether international law grants state immunity in relation to the international crime of torture and, if so, whether the Republic of Chile is entitled to claim such immunity even though Chile, Spain and the United Kingdom are all parties to the Torture Convention and therefore & quot;contractually" bound to give effect to its provisions from 8 December 1988 at the latest.
It is a basic principle of international law that one sovereign state (the forum state) does not adjudicate on the conduct of a foreign state. The foreign state is entitled to procedural immunity from the processes of the forum state. This immunity e xtends to both criminal and civil liability. State immunity probably grew from the historical immunity of the person of the monarch. In any event, such personal immunity of the head of state persists to the present day: the head of state is entitled to the same immunity as the state itself. The diplomatic representative of the foreign state in the forum state is also afforded the same immunity in recognition of the dignity of the state which he represents. This immunity enjoyed by a head of state in p ower and an ambassador in post is a complete immunity attaching to the person of the head of state or ambassador and rendering him immune from all actions or prosecutions whether or not they relate to matters done for the benefit of the state. Such immun ity is said to be granted ratione personae.
What then when the ambassador leaves his post or the head of state is deposed? The position of the ambassador is covered by the Vienna Convention on Diplomatic Relations, 1961. After providing for immunity from arrest (Article 29) and from criminal a nd civil jurisdiction (Article 31), Article 39(1) provides that the ambassador's privileges shall be enjoyed from the moment he takes up post; and subsection (2) provides:
The continuing partial immunity of the ambassador after leaving post is of a different kind from that enjoyed ratione personae while he was in post. Since he is no longer the representative of the foreign state he merits no particular privileges or im munities as a person. However in order to preserve the integrity of the activities of the foreign state during the period when he was ambassador, it is necessary to provide that immunity is afforded to his official acts during his tenure in post. If this were not done the sovereign immunity of the state could be evaded by calling in question acts done during the previous ambassador's time. Accordingly under Article 39(2) the ambassador, like any other official of the state, enjoys immunity in re lation to his official acts done while he was an official. This limited immunity, ratione materiae, is to be contrasted with the former immunity ratione personae which gave complete immunity to all activities whether public or private.
In my judgment at common law a former head of state enjoys similar immunities, ratione materiae, once he ceases to be head of state. He too loses immunity ratione personae on ceasing to be head of state: see Watts The Legal Position in Internationa l Law of Heads of States, Heads of Government and Foreign Ministers p. 88 and the cases there cited. He can be sued on his private obligations: Ex-King Farouk of Egypt v. Christian Dior (1957) 24 I.L.R. 228; Jimenez v. Aristeguieta (196 2) 311 F. 2d 547. As ex head of state he cannot be sued in respect of acts performed whilst head of state in his public capacity: Hatch v. Baez  7 Hun. 596. Thus, at common law, the position of the former ambassador and the former head of s tate appears to be much the same: both enjoy immunity for acts done in performance of their respective functions whilst in office.
I have belaboured this point because there is a strange feature of the United Kingdom law which I must mention shortly. The State Immunity Act 1978 modifies the traditional complete immunity normally afforded by the common law in claims for damages ag ainst foreign states. Such modifications are contained in Part I of the Act. Section 16(1) provides that nothing in Part I of the Act is to apply to criminal proceedings. Therefore Part I has no direct application to the present case. However, Part II I of the Act contains section 20(1) which provides:
(b) . . .
(c) . . .
as it applies to a head of a diplomatic mission . . ."
The correct way in which to apply Article 39(2) of the Vienna Convention to a former head of state is baffling. To what "functions" is one to have regard? When do they cease since the former head of state almost certainly never arrives in th is country let alone leaves it? Is a former head of state's immunity limited to the exercise of the functions of a member of the mission, or is that again something which is subject to "necessary modification"? It is hard to resist the suspici on that something has gone wrong. A search was done on the parliamentary history of the section. From this it emerged that the original section 20(1)(a) read "a sovereign or other head of state who is in the United Kingdom at the invitation or w ith the consent of the Government of the United Kingdom." On that basis the section would have been intelligible. However it was changed by a Government amendment the mover of which said that the clause as introduced "leaves an unsatisfact ory doubt about the position of heads of state who are not in the United Kingdom"; he said that the amendment was to ensure that heads of state would be treated like heads of diplomatic missions "irrespective of presence in the United Kingdom.&q uot; The parliamentary history, therefore, discloses no clear indication of what was intended. However, in my judgment it does not matter unduly since Parliament cannot have intended to give heads of state and former heads of state greater rights than t hey already enjoyed under international law. Accordingly, "the necessary modifications" which need to be made will produce the result that a former head of state has immunity in relation to acts done as part of his official functions when head o f state. Accordingly, in my judgment, Senator Pinochet as former head of state enjoys immunity ratione materiae in relation to acts done by him as head of state as part of his official functions as head of state.
The question then which has to be answered is whether the alleged organisation of state torture by Senator Pinochet (if proved) would constitute an act committed by Senator Pinochet as part of his official functions as head of state. It is not enough to say that it cannot be part of the functions of the head of state to commit a crime. Actions which are criminal under the local law can still have been done officially and therefore give rise to immunity ratione materiae. The case needs to be analysed more closely.
Can it be said that the commission of a crime which is an international crime against humanity and jus cogens is an act done in an official capacity on behalf of the state? I believe there to be strong ground for saying that the implementation of tort ure as defined by the Torture Convention cannot be a state function. This is the view taken by Sir Arthur Watts (supra) who said (at p. 82):
Later, at p. 84, he said:
It can be objected that Sir Arthur was looking at those cases where the international community has established an international tribunal in relation to which the regulating document expressly makes the head of state subject to the tribunal's ju risdiction: see, for example, the Nuremberg Charter Article 7; the Statute of the International Tribunal for former Yugoslavia; the Statute of the International Tribunal for Rwanda and the Statute of the International Criminal Court. It is true that in t hese cases it is expressly said that the head of state or former head of state is subject to the court's jurisdiction. But those are cases in which a new court with no existing jurisdiction is being established. The jurisdiction being established by the Torture Convention and the Hostages Convention is one where existing domestic courts of all the countries are being authorised and required to take jurisdiction internationally. The question is whether, in this new type of jurisdiction, the only possible view is that those made subject to the jurisdiction of each of the state courts of the world in relation to torture are not entitled to claim immunity.
I have doubts whether, before the coming into force of the Torture Convention, the existence of the international crime of torture as jus cogens was enough to justify the conclusion that the organisation of state torture could not rank for immunity pur poses as performance of an official function. At that stage there was no international tribunal to punish torture and no general jurisdiction to permit or require its punishment in domestic courts. Not until there was some form of universal jurisdiction for the punishment of the crime of torture could it really be talked about as a fully constituted international crime. But in my judgment the Torture Convention did provide what was missing: a worldwide universal jurisdiction. Further, it required all member states to ban and outlaw torture: Article 2. How can it be for international law purposes an official function to do something which international law itself prohibits and criminalises? Thirdly, an essential feature of the international crime of torture is that it must be committed "by or with the acquiesence of a public official or other person acting in an official capacity." As a result all defendants in torture cases will be state officials. Yet, if the former head of state has imm unity, the man most responsible will escape liability while his inferiors (the chiefs of police, junior army officers) who carried out his orders will be liable. I find it impossible to accept that this was the intention.
Finally, and to my mind decisively, if the implementation of a torture regime is a public function giving rise to immunity ratione materiae, this produces bizarre results. Immunity ratione materiae applies not only to ex-heads of state and ex-ambassad ors but to all state officials who have been involved in carrying out the functions of the state. Such immunity is necessary in order to prevent state immunity being circumvented by prosecuting or suing the official who, for example, actually carried out the torture when a claim against the head of state would be precluded by the doctrine of immunity. If that applied to the present case, and if the implementation of the torture regime is to be treated as official business sufficient to found an immunity for the former head of state, it must also be official business sufficient to justify immunity for his inferiors who actually did the torturing. Under the Convention the international crime of torture can only be committed by an official or someone in a n official capacity. They would all be entitled to immunity. It would follow that there can be no case outside Chile in which a successful prosecution for torture can be brought unless the State of Chile is prepared to waive its right to its officials i mmunity. Therefore the whole elaborate structure of universal jurisdiction over torture committed by officials is rendered abortive and one of the main objectives of the Torture Convention--to provide a system under which there is no safe haven for tortu rers--will have been frustrated. In my judgment all these factors together demonstrate that the notion of continued immunity for ex-heads of state is inconsistent with the provisions of the Torture Convention.
For these reasons in my judgment if, as alleged, Senator Pinochet organised and authorised torture after 8 December 1988, he was not acting in any capacity which gives rise to immunity ratione materiae because such actions were contrary to internationa l law, Chile had agreed to outlaw such conduct and Chile had agreed with the other parties to the Torture Convention that all signatory states should have jurisdiction to try official torture (as defined in the Convention) even if such torture were commit ted in Chile.
As to the charges of murder and conspiracy to murder, no one has advanced any reason why the ordinary rules of immunity should not apply and Senator Pinochet is entitled to such immunity.
For these reasons, I would allow the appeal so as to permit the extradition proceedings to proceed on the allegation that torture in pursuance of a conspiracy to commit torture, including the single act of torture which is alleged in charge 30, was bei ng committed by Senator Pinochet after 8 December 1988 when he lost his immunity.
In issuing to the magistrate an authority to proceed under section 7 of the Extradition Act 1989, the Secretary of State proceeded on the basis that the whole range of torture charges and murder charges against Senator Pinochet would be the subject mat ter of the extradition proceedings. Your Lordships' decision excluding from consideration a very large number of those charges constitutes a substantial change in the circumstances. This will obviously require the Secretary of State to reconsider his de cision under section 7 in the light of the changed circumstances.
LORD GOFF OF CHIEVELEY
The background to the present appeal is set out, with economy and lucidity, in the opinion of my noble and learned friend Lord Browne-Wilkinson, which I have had the opportunity of reading in draft. I gratefully adopt his account and, to keep my own o pinion as short as reasonably possible, I do not propose to repeat it. The central question in the appeal is whether Senator Pinochet is entitled as former head of state to the benefit of state immunity ratione materiae in respect of the charges advanced against him, as set out in the schedule of charges prepared by Mr. Alun Jones Q.C. on behalf of the Government of Spain.
II. The principal issue argued on the appeal
Before the Divisional Court, and again before the first Appellate Committee, it was argued on behalf of the Government of Spain that Senator Pinochet was not entitled to the benefit of state immunity basically on two grounds, viz. first, that the crime s alleged against Senator Pinochet are so horrific that an exception must be made to the international law principle of state immunity; and second, that the crimes with which he is charged are crimes against international law, in respect of which state im munity is not available. Both arguments were rejected by the Divisional Court, but a majority of the first Appellate Committee accepted the second argument. The leading opinion was delivered by Lord Nicholls of Birkenhead, whose reasoning was of great s implicity. He said (see  3 W.L.R. 1456 at p. 1500C-F):
Lord Hoffmann agreed, and Lord Steyn delivered a concurring opinion to the same effect.
Lord Slynn of Hadley and Lord Lloyd of Berwick, however, delivered substantial dissenting opinions. In particular, Lord Slynn (see  3 W.L.R. 1456 at pp. 1471F-1475G) considered in detail "the developments in international law relating to w hat are called international crimes." On the basis of the material so reviewed by him, he concluded (at p. 1473C):
He went on to consider whether international law now recognises that some crimes, and in particular crimes against humanity, are outwith the protection of head of state immunity. He referred to the relevant material, and observed at p. 1474H:
He then proceeded to examine the Torture Convention of 1984, the Genocide Convention of 1948 and the Taking of Hostages Convention of 1983, and concluded that none of them had removed the long established immunity of former heads of state.
I have no doubt that, in order to consider the validity of the argument advanced on behalf of the Government of Spain on this point, it was necessary to carry out the exercise so performed by Lord Slynn; and I am therefore unable, with all respect, to accept the simple approach of the majority of the first Appellate Committee. Furthermore, I wish to record my respectful agreement with the analysis, and conclusions, of Lord Slynn set out in the passages from his opinion to which I have referred. I int end no disrespect to the detailed arguments advanced before your Lordships on behalf of the appellants in this matter, when I say that in my opinion they did not succeed in shaking the reasoning, or conclusions, of Lord Slynn which I have set out above. However, having regard to (1) the extraordinary impact on this case of the double criminality rule, to which I will refer in a moment, and (2) the fact that a majority of your Lordships have formed the view that, in respect of the very few charges (of tor ture or conspiracy to torture) which survive the impact of the double criminality rule, the effect of the Torture Convention is that in any event Senator Pinochet is not entitled to the benefit of state immunity, the present issue has ceased to have any d irect bearing on the outcome of the case. In these circumstances, I do not consider it necessary or appropriate to burden this opinion with a detailed consideration of the arguments addressed to the Appellate Committee on this issue. However, I shall re turn to the point when I come to consider the topic of state immunity later in this opinion.
III The double criminality rule
During the course of the hearing before your Lordships, two new issues emerged or acquired an importance which they had not previously enjoyed. The first of these is the issue of double criminality, to which I now turn.
At the hearing before your Lordships Mr. Alun Jones Q.C., for the appellants, sought to extend backwards the period during which the crimes charged were alleged to have been committed, with the effect that some of those crimes could be said to have tak en place before the coup following which Senator Pinochet came into power. The purpose was obviously to enable the appellants to assert that, in respect of these crimes, no immunity as former head of state was available to him. As a result Miss Clare Mo ntgomery Q.C., for Senator Pinochet, revived the submission that certain of the charges related to crimes which were not extradition crimes because they were not, at the time they were alleged to have been committed, criminal under the law of this country , thus offending against the double criminality rule. Mr. Alun Jones Q.C. replied to this argument but, for the reasons given by my noble and learned friend Lord Browne-Wilkinson, with which I am respectfully in complete agreement, I too am satisfied tha t Miss Montgomery's submission was well-founded.
The appellants did not, however, analyse the consequences of this argument, if successful, in order to identify the charges against Senator Pinochet which would survive the application of the double criminality rule. That substantial task has, however, been undertaken by my noble and learned friend, Lord Hope of Craighead, to whom your Lordships owe a debt of gratitude. His analysis I respectfully accept. As he truly says, the impact upon the present case is profound. The great mass of the offences with which Senator Pinochet is charged must be excluded, as must also be the charge of hostage-taking which does not disclose an offence under the Taking of Hostages Act 1982. The principal charges which survive are those which relate to acts of torture alleged to have been committed, or conspiracies to torture which are alleged to have been active, after 29 September 1988, the date on which section 134 of the Criminal Justice Act 1988 (which gave effect to the Torture Convention in this country) came in to effect. These are: charge 30, which relates to a single act of torture alleged to have been committed on 24 June 1989; and charges 2 and 4, which allege conspiracies to torture between 1 August 1973 and 1 January 1972 respectively, and 1 January 1990, in so far as they relate to the relatively brief period between 29 September 1988 and 1 January 1990. In addition, however, the charge of conspiracy to commit murder in Spain (charge 9), and such conspiracies to commit murder in Spain as can be shown to form part of the allegations in charge 4, also survive.
IV. State immunity
Like my noble and learned friend Lord Browne-Wilkinson, I regard the principles of state immunity applicable in the case of heads of state and former heads of state as being relatively non-controversial, though the legislation on which they are now bas ed, the State Immunity Act 1978, is in a strange form which can only be explained by the legislative history of the Act.
There can be no doubt, in my opinion, that the Act is intended to provide the sole source of English law on this topic. This is because the long title to the Act provides (inter alia) that the Act is "to make new provision with regard to t he immunities and privileges of heads of state." Since in the present case we are concerned with immunity from criminal process, we can ignore Part I (which does not apply to criminal proceedings) and turn straight to Part III, and in particular to section 20. Section 20(1) provides as follows:
The function of the Diplomatic Privileges Act 1964 is to give effect to the Vienna Convention on Diplomatic Relations in this country, the relevant articles of which are scheduled to the Act. The problem is, of course, how to identify the "necess ary modifications" when applying the Vienna Convention to heads of state. The nature of the problem is apparent when we turn to Article 39 of the Convention, which provides:
At first this seems very strange, when applied to a head of state. However, the scales fall from our eyes when we discover from the legislative history of the Act that it was originally intended to apply only to a sovereign or other head of state in t his country at the invitation or with the consent of the government of this country, but was amended to provide also for the position of a head of state who was not in this country--hence the form of the long title, which was amended to apply simply to he ads of state. We have, therefore, to be robust in applying the Vienna Convention to heads of state "with the necessary modifications". In the case of a head of state, there can be no question of tying Article 39(1) or (2) to the territory of t he receiving state, as was suggested on behalf of the appellants. Once that is realised, there seems to be no reason why the immunity of a head of state under the Act should not be construed as far as possible to accord with his immunity at customary int ernational law, which provides the background against which this statute is set: see Alcom Ltd. v. Republic of Colombia  1 A.C. 580, 597G, per Lord Diplock. The effect is that a head of state will, under the statute as at internationa l law, enjoy state immunity ratione personae so long as he is in office, and after he ceases to hold office will enjoy the concomitant immunity ratione materiae "in respect of acts performed [by him] in the exercise of his functions [as head of state ]", the critical question being "whether the conduct was engaged in under colour of or in ostensible exercise of the head of state's public authority" (see The Legal Position in International Law of Heads of States, Heads of Governments and Foreign Ministers by Sir Arthur Watts, Recueil des Cours, vol. 247 (1994-III), at p. 56). In this context, the contrast is drawn between governmental acts, which are functions of the head of state, and private acts, which are not.
There can be no doubt that the immunity of a head of state, whether ratione personae or ratione materiae, applies to both civil and criminal proceedings. This is because the immunity applies to any form of legal process. The principle of state immuni ty is expressed in the Latin maxim par in parem non habet imperium, the effect of which is that one sovereign state does not adjudicate on the conduct of another. This principle applies as between states, and the head of a state is entitled to the same immunity as the state itself, as are the diplomatic representatives of the state. That the principle applies in criminal proceedings is reflected in the Act of 1978, in that there is no equivalent provision in Part III of the Act to section 16(4) w hich provides that Part I does not apply to criminal proceedings.
However, a question arises whether any limit is placed on the immunity in respect of criminal offences. Obviously the mere fact that the conduct is criminal does not of itself exclude the immunity, otherwise there would be little point in the immunity from criminal process; and this is so even where the crime is of a serious character. It follows, in my opinion, that the mere fact that the crime in question is torture does not exclude state immunity. It has however been stated by Sir Arthur Watts (o p. cit. at pp. 81-84) that a head of state may be personally responsible:
