¹¹ Chan (n 7) 940 n 56. A mainland law purporting to implement the Convention and Protocol within Hong Kong would, on the current terms of the Basic Law, almost certainly be invalid: Basic Law, Art 18. However, this could be avoided if the mainland law were combined with a mainland reinterpretation of the Basic Law, which may supplement that instrument: Art 158; Director of Immigration v Chong Fung Yuen [2001] 2 HKLRD 533. The scope for such an extraordinary step, which is tantamount to a constitutional amendment, surely cannot preclude the operation of the federal clauses in the Convention and Protocol, which must refer to regular or at least unamended federal constitutional competence.

Compare Third Periodic Report of China to Committee Against Torture (5 January 2000, UN Doc CAT/C/39/Add 2) (‘the Report’), para.s 95, 114; FB v Director of Immigration (unreported, Hong Kong Court of First Instance, Saunders J, 5 December 2008), para 112. As Saunders J notes, the Order has the effect that ‘an application by a government of a place outside Hong Kong to the surrender of the fugitive offender is made subject to the [Torture] Convention’. This means, in light of s 2 of the Order, that the Ordinance applies in relation to states parties to the Torture Convention ‘subject to limitations, restrictions, exceptions and qualifications’ in that instrument. Thus, no surrender under the Ordinance to such a state party may contravene Art 3(1). It is puzzling then why, much like the Report, Saunders J went on to state that ‘[c]onsequently, as a matter of discretion Hong Kong may refuse to surrender a person where that surrender may be in breach of the [Torture] Convention’.

¹⁰³ There is also little mileage in a broader reservation made by the United Kingdom regarding the non-effect of rights under the ICCPR in the application of immigration legislation: see, generally, Tam Nga Yin v Director of Immigration (2001) 4 HKCFAR 251, 260 (Li CJ, Chan, Ribeiro PJJ, Sir Anthony Mason NPJ). While violation of those rights could overlap with refugee status, the reservation just described concerns the former and thus is not sufficiently targeted to ground persistent objection to the latter.

¹⁰⁴ That insulation is a little more complex than Hartmann J suggested. Art 22 was originally the subject of a specific declaration regarding the detention, screening and entry into/departure from Hong Kong of children seeking refugee status. This declaration was withdrawn on 10 April 2003. However a broader reservation, resembling that mentioned in n 101 for the ICCPR, remains in place: http://www2.ohchr.org/english/bodies/ratification/11.htm#N4 (visited 8 January 2009). Its main concern is necessarily Art 22, being the key provision on the application of CROC in immigration cases: S Detrick, Commentary on United Nations Convention on Rights of Child (Martinus Nijhoff, Hague, 1999) 366. To the extent that the broader reservation impacts beyond Art 22, it is irrelevant to persistent objection for the reasons given in n 103. In any event, there appears to be some talk of its withdrawal: Second Periodic Report to Committee on Rights of Child (24 Sep 2004, CRC/C/83/Add.9), para 537; Concluding Observations of Committee on Rights of Child (30 September 2005, CRC/C/15/Add.271), para 8.

¹⁶⁰ Bennion (n 86) has criticized Brind on other grounds: see 821.

¹⁶¹ Nor, for the same reason, were any separate presumptions, such as preservation of the common law: Bennion (n 86) 814–815. The position is obviously different in the UK, following the incorporation of non-refoulement of refugees into domestic law: see n 128; R v Secretary of State for Home Department; Ex parte Adan [2001] 2 AC 477, 526, 527, 531. It should be added that it seems wrong to sidestep the above reasoning simply by pointing to the potential overlap between fundamental rights attracting the principle of legality (or the broadly related principle against doubtful penalization) and non-refoulement of refugees, eg on matters such as human life or health: see, generally, Bennion (n 86) 822–823, 825–836, 844–845. First, it is not obvious that the principle of legality applies in relation to extra-territorial violations relevantly divorced from the home government: A v Secretary of State for Home Department (No 2) [2006] 2 AC 221; Roma (n 59) 40–41. Further, by one means or another, Hong Kong courts have refused to limit the general discretions according to such matters: Lau (n 28), 808; Bahadur (n 81), 125; Tran Van Tien v Director of Immigration [1997] HKLRD 183, 189–191, 194. Of course, the principle of legality resembles remedial interpretation under s 3 of the HRA. However, the equivalent of the latter in Hong Kong is, in relation to rights recognised by the ICCPR, unavailable in the immigration context: Bill of Rights Ordinance (Cap 383) s 8 Arts 3 and 5, s 11; Tam Nga Yin (n 103), 260; Koon Wing Yee v Insider Dealing Tribunal [2008] 3 HKLRD 372. It is likewise, in relation to other constitutionally protected rights, arguably unavailable in respect of matters outside of Hong Kong, again where relevantly divorced from the home government: see Basic Law, Art 41; HKSAR v Lam Kwong Wai [2006] 3 HKLRD 372 and, generally, Chu Woan Chyi v Director of Immigration [2007] 3 HKC 168, 190–192.

Compare Commissioner of Rating and Valuation v Agrila Ltd [2001] 2 HKLRD 36, 55 (Sir Anthony Mason NPJ) (Li CJ, Bokhary PJ, Chan PJ and Litton NPJ agreeing); HKSAR v Yav Mee Kwan [2004] 1 HKLRD A6; Solicitor (24/7) v Law Society of Hong Kong [2008] 2 HKLRD 576.

¹⁶⁴ See, eg, Lai Tak Shing v Director of Home Affairs (unreported, Hong Kong Court of Appeal, CACV 201/2005, 9 October 2006) [23]–[25] (Cheung JA) (Yam and Sakhrani JJA agreeing), reversed on other grounds: (unreported, Hong Kong Court of Final Appeal, FACV 5/2007, 5 November 2007). While Hong Kong law generously recognises legitimate expectations, a procedural legitimate expectation is simply a more arduous route to the relevant consideration point made below. The relevant substantive legitimate expectation, presumably based on Hong Kong's practice of not repatriating refugees, is not inconceivable. If found, it would limit the general discretions. However, it would impact on an order by the Hong Kong government for the repatriation of refugees, which is highly unlikely: Ng Siu Tung v Director of Immigration [2002] 1 HKLRD 561.

¹⁸² See, generally, Hogg (n 175) 128–136.

¹⁸³ [1939] AC 160, 168 (Lord Atkin, for the Board).

¹⁸⁴ Hogg (n 175) 142–149. It is not to the point that public international law imposes the obligation on the state, with the conduct of officials merely being subject to a rule of attribution. The discretion of the courts under Trendtex reflects a latitude that states undoubtedly have under public international law regarding the approach they take to bringing public international norms to the municipal plane.

¹⁸⁵ Crown Proceedings Act 1947 (UK), s 2(1); Crown Proceedings Ordinance (Cap 300), s 4(1). As Hogg (n 175) notes, 142, ‘ … the Crown is liable in tort only under recognized heads of private tortious liability. There is no special “public” law of torts’.

¹⁸⁶ Hogg (n 175) 110–111.

¹⁸⁷ Note that the position could be different if the tort of exile were excluded by statute or if issues of non-justiciability arose: see, eg, West Rand Central Gold Mining Company v King [1905] 2 KB 391; compare R (Bancoult) v Secretary of State for Foreign and Commonwealth Affairs (No 2) [2008] 3 WLR 955. The same would not necessarily flow from the tort of breach of statutory duty. It requires (a) a breach of a public obligation in favour of particular people; and (b) a legislative intent to impose civil liability sounding in damages for that breach: see, eg, X (Minors) v Bedfordshire County Council [1995] 2 AC 633. If the second requirement were not fulfilled, it might well mean that a customary tort had also been excluded. However, the non-satisfaction of the first requirement, eg due to the presence of a statutory discretion rather than an obligation or generality rather than specific beneficiaries, ought to have no such effect. Rather, if administrative conduct related to a provision of that character contravened a customary norm, then another, distinct form of civil liability, such as the tort of exile, could simply step in. In this way, customary torts could co-exist with the tort of breach of statutory duty, much as it already co-exists with others.

¹⁸⁹ See, in light of n 135, Australian Constitution, s 109.

¹⁹⁰ Indeed, this is the view of the Canadian courts, albeit in a context where unincorporated conventional obligations may also be relevant considerations: Baker (n 87); Hape (n 158); Munar v Canada [2005] FC 1180; Okoloubu v Canada [2007] FC 1069.

¹⁹¹ It could also be argued that the Director or Immigration official, when taking into account the relevant consideration, could not have imputed to him or her the knowledge of the UNHCR. See, by analogy, R (National Association of Health Stores) v Department of Health [2005] EWCA Civ 154. Compare International Trader Ltd v Town Planning Appeal Board (unreported, Hong Kong Court of First Instance, A Cheung J, 15 November 2007) and authority cited there. Lastly the process may be vulnerable on the ground that the UNHCR, rather than the Director or immigration official, conducts interviewing on the Convention and Protocol: FB v Director of Immigration [2009] 1 HKC 133.
