“There is really no dispute about the proper approach to the construction of the Rules. As Lord Hoffmann said in Odelola v Secretary of State for the Home Department[2009] 1 WLR 1230 , 1233 (paragraph 4): "Like any other question of construction, this [whether a rule change applies to all undetermined applications or only to subsequent applications] depends upon the language of the rule, construed against the relevant background. That involves a consideration of the immigration rules as a whole and the function which they serve in the administration of immigration policy." That is entirely consistent with what Buxton LJ (collecting together a number of dicta from past cases concerning the status of the rules) had said in Odelola in the Court of Appeal ([2009] 1 WLR 126 ) and, indeed, with what Laws LJ said (before the House of Lords decision in Odelola) in the present case. Essentially it comes to this. The Rules are not to be construed with all the strictness applicable to the construction of a statute or a statutory instrument but, instead, sensibly according to the natural and ordinary meaning of the words used, recognising that they are statements of the Secretary of State's administrative policy. The respondent's counsel readily accepted that what she meant in her written case by the proposition "the question of interpretation is . . . what the Secretary of State intended his policy to be" was that the court's task is to discover from the words used in the Rules what the Secretary of State must be taken to have intended. After all, undersection 3(2) of the Immigration Act 1971 , the Secretary of State has to lay the Rules before Parliament which then has the opportunity to disapprove them. True, as I observed in Odelola (para 33): "the question is what the Secretary of State intended. The rules are her rules." But that intention is to be discerned objectively from the language used, not divined by reference to supposed policy considerations. Still less is the Secretary of State's intention to be discovered from the Immigration Directorates' Instructions (IDIs) issued intermittently to guide immigration officers in their application of the rules.”
