12 Take, for instance, the reactions of the United Kingdom to the implications of the Hirst case (ECtHR, Judgment of 30 March 2005, Hirst v. The United Kingdom (No. 2)) in which the United Kingdom was urged to abolish the voting prohibition for prisoners. Many MPs protested against the ‘the British submission to foreign judges’ and the alleged infringement of sovereignty; see, on this controversy, ‘Prisoners’ Voting Rights: Britain's Mounting Fury over Sovereignty’, The Economist, 10 February 2011, available at www.economist.com/blogs/bagehot/2011/02/prisoners_voting_rights; think, in the same vein, about the French and Dutch dismissal of the European Constitution.

26 Maurice Adams and Willem Witteveen have recently made the same sort of distinction between an institutional perspective, which is focused on formal hierarchic norms (who has ultimate sovereignty?), and a material perspective, which is focused on the quality of norms, in Adams, M. and Witteveen, W., ‘Gedaanteverwisselingen van het recht’, (2011) 86 Nederlands Juristenblad 540Google Scholar.

36 See, e.g., Benvenisti, E., ‘Reclaiming Democracy: The Strategic Uses of Foreign and International Law by Domestic Courts’, (2008) 102 AJIL 241CrossRefGoogle Scholar. Benvenisti states that national courts use international law primarily for their own interest, namely ‘to expand the space for domestic deliberation, to strengthen the ability of national governments to withstand the pressure brought to bear by interest groups and powerful foreign governments, and to insulate the national courts from intergovernmental pressures’, at 242.

37 In Kadi, the ECJ stressed that the European legal system constitutes an autonomous legal order, which permitted them to take a dualist position. As such, they circumvented Art. 103 of the UN Charter (Kadi, supra note 29); in Ahmed and Others, the UK Supreme Court used the dualist position as well and examined whether the parliament that implemented the UN Charter in 1946 would have agreed with these specific counterterrorism sanctions. In so doing, they circumvented the obligations of the UN Charter and created the possibility of a new democratic check; Ahmed and Others, supra note 28; see also subsection 4.1.

38 Take, for instance, the reservations made by Islamic countries to many human rights treaties. These reservations are in a way comparable to the Solange approach taken by the German Bundesverfassungsgericht in the European context, which is seen by Krisch as a pluralist tendency. Both form an ex ante restraint on the basis of values. Legal pluralism favoured by Krisch would open the possibility of ex post reviewing on the basis of the same values. Examples of protection of national interests are the British Horncastle case (R v. Horncastle and Others, [2009] UKSC 14) and the Medellin decision of the US Supreme Court (Medellin v. Texas, 552 US 491 (2008)).

39 UNSC Res. 1267, UN Doc. S/RES/1267 (1999) was issued in 1999 after the bombings of the US embassies in Dar es Salaam and Nairobi and targeted at Usuma Bin Laden and the Taliban regime that provided a safe haven for al Qaeda; UNSC Res. 1373, UN Doc. S/RES/1373 (2001) was issued just after the 9/11 attack and had a wider mandate, since it considered all terrorist organizations.
