⁴ There were previous attempts to apply and ultimately dismiss the model of legal pluralism for analysing the relationship between the Mainland Chinese and HK legal systems. See Ghai, Yash, “Litigating the Basic Law: Jurisdiction, Interpretation and Procedure” in Chan, Johannes MM, Fu, HL, Ghai, Yash, eds., Hong Kong's Constitutional Debate: Conflict Over Interpretation (HK: HK University Press, 2000) [hereinafter “HK's Constitutional Debate”], at 10Google Scholar; Ghai, Yash, “The Intersection of Chinese Law and the Common Law in the HKSAR: Question of Technique or Politics?” (2007) 37 Hong Kong Law Journal [hereinafter “HKLJ”] 363, at 367Google Scholar. For my response to Ghai's argument, see infra note 25 and accompanying text. In addition, Alice Tay explained how legal pluralism did not fit the ideology of communist China. Tay, Alice ES, “People's Republic of China” in Tan, Poh-Ling, Asian Legal Systems (Butterworths, 1997), at 63Google Scholar. It is beyond the scope of this article to fully respond to this argument. Suffice to say that this article focuses on what the relationship between legal systems in fact is, which may or may not be in line with the ideology of the ruling government.

⁶⁸ Lau Kong Yung, supra note 59.

⁶⁹ E.g. Chong Fung Yuen, supra note 59 at section 7.4. The CFA held that the court should examine the “character” of the provision to decide whether it was an excluded provision. See also the Congo Case, (CFI), supra note 35 at paras. 45-46, 72-73; The Congo Case (CA), supra note 36 at paras. 34-44. Although, it must be noted that the CFA in Lau Kong Yung (at 800-F) and Chong Fung Yuen (at section 7.5) indicated that the “predominant provision” test might have to be revisited in future if the appropriate case arose.

⁷⁰ In a procedural hearing on 30 June 2010, the Congo government asked the CFA to consider seeking an NPCSC interpretation on arts 8, 13 and 19, BL. See Press Release issued by the HK Judiciary on 20 July 2010, available at <http://www.info.gov.hk/gia/general/201007/20/ P201007200253.htm> (last accessed on 18 August 2010).

⁷¹ The Ng Ka Ling Interpretation was made without judicial reference. One of the subject articles for interpretation (art. 24(2)(3), BL) was a provision falling within HK's autonomy. The CFA in Lau Kong Yung, supra note 59, through accepting the Interpretation, accepts both free-standing aspects of the NPCSC's interpretative power. The court's acceptance of the free-standing nature of the NPCSC's interpretative power is confirmed in later cases, see e.g. Chong Fung Yuen, supra note 59 at section 6.2.

⁷² For example, Chen contrasted federalism with OCTS by pointing out, inter alia, that whereas jurisdictional conflicts in the former are resolved by an independent court, in the latter, they are resolved by the NPCSC acting in consultation with the BL Committee. Chen, Albert HY, “The Theory, Constitution and Practice of Autonomy: The Case of Hong Kong” in Oliveira, Jorge and Cardinal, Paulo, eds., One Country, Two Systems, Three Legal Orders – Perspectives of Evolution (Springer, 2009), at 761Google Scholar. Similar assertions on the NPCSC being “arbiter” have been made in the context of lamenting the lack of impartial arbiter on jurisdictional disputes between the two systems.

⁷⁴ Including India, Bangladesh, and Pakistan.

⁷⁵ Elaborated in the JD (cl. 3 and Annex I) and stipulated to remain unchanged for 50 years (cl. 3(12), JD); stated to be unamendable in the BL (art. 159(4), BL).

⁷⁶ Ghai, “Litigating the Basic Law: Jurisdiction, Interpretation and Procedure” in HK's Constitutional Debate, supra note 4 at 48.

⁷⁷ The 2004 Interpretation was made on the NPCSC's own initiative, in relation to provisions on constitutional reform in HK. The 2005 Interpretation was made on the HK Chief Executive's request, in relation to the term of office of the Chief Executive. The Interpretation by the NPCSC of art. 7 of Annex I and article III of Annex II of the Basic Law of the Hong Kong Special Administrative Region of the People's Republic of China, adopted by the Standing Committee of the Tenth National People's Congress at its Eighth Session on 6 April 2004; the Interpretation of para. 2, art. 53 of the Basic Law of the Hong Kong Special Administrative Region of the People's Republic of China, adopted at the 15^th Session of the Standing Committee of the Tenth National People's Congress on 27 April 2005.

⁷⁸ See supra note 29.
