“been assisted by the discussion at paragraph 3.26 of Human Rights Law and Practice (Butterworth 1999), of which Lord Lester of Herne Hill QC and David Pannick QC are the general editors. They identify the following factors: (a) the nature of the Convention right: is the right absolute or (as in the case of Article 8) does it require a balance to be struck? The court is less likely to defer to the opinion of the decision-maker in the former case than the latter. (b) the extent to which the issues require consideration of social, economic or political factors. The court will usually accord considerable deference in such cases because it is not expert in the realm of policy-making, nor should it be because it is not democratically elected or accountable. (c) The extent to which the court has special expertise, for example in relation to criminal matters. (d) Where the rights claimed are of especial importance, ‘a high degree of constitutional protection’ will be appropriate. The European Court of Human Rights has recognised as being of especial importance rights to freedom of expression and access to the courts” 61. As to factor (a) in this formulation, there has been a dispute as to whether article 12 is an absolute right or a right which requires a balance to be struck. In my view, article 12 is not an absolute right because, as I have explained in paragraphs 50 to 57 above, the last eleven words of article 12 entitle member states to strike a balance because, as was explained in Hamer v United Kingdom, at §62, those states “may also lay down rules of substance based on recognised considerations of public interest” 62. Moving to factor (b), issues of immigration and sham marriages are classic examples of areas, which require consideration of social and also political issues and in these matters the legislature and the executive are entitled to substantial deference because they, unlike the judiciary, are the designated experts in the realm of policy-making in these fields. The remaining factors show that the Secretary of State and the legislature are entitled to substantial deference because as to factor (c), the courts do not have any special expertise on immigration policy and in respect of factor (d), the right to marry, although an important fundamental right, does not qualify as one of “the rights claimed ... of especial importance”
