“Had Ms de Silva’s sponsors been privy to the new rules, suitable maintenance funds would have been made available to Ms de Silva and appeared in her personal bank account in accordance with the ‘Maintenance funds’ scoring system. Ms de Silva is now unable to complete her studies and take her examinations: firstly, the rules that allowed her entry into the UK to fulfil her educational aspirations have been revoked before completion of the said course and examinations and, secondly, the UK citizens previously deemed suitable sponsors for an individual wishing to be educated in the UK are no longer deemed suitable.”
“17. The authority will wish to consider and weigh all that tells in favour of the refusal of leave which is challenged, with particular reference to justification under article 8(2). There will, in almost any case, be certain general considerations to bear in mind: the general administrative desirability of applying known rules if a system of immigration control is to be workable, predictable, consistent and fair as between one applicant and another; the damage to good administration and effective control if a system is perceived by applicants internationally to be unduly porous, unpredictable or perfunctory; the need to discourage non-nationals admitted to the country temporarily from believing that they can commit serious crimes and yet be allowed to remain; the need to discourage fraud, deception and deliberate breaches of the law; and so on. 18. … It is a premise of the statutory scheme enacted by Parliament that an applicant may fail to qualify under the Rules and yet may have a valid claim by virtue of Article 8. 19. In de Freitas v Permanent Secretary of Ministry of Agriculture, Fisheries, Lands and Housing[1999] 1 AC 69 , 80, the Privy Council, drawing on South African, Canadian and Zimbabwean authority, defined the questions generally to be asked in deciding whether a measure is proportionate: "whether: (i) the legislative objective is sufficiently important to justify limiting a fundamental right; (ii) the measures designed to meet the legislative objective are rationally connected to it; and (iii) the means used to impair the right or freedom are no more than is necessary to accomplish the objective." This formulation has been widely cited and applied. But counsel for the applicants (with the support of Liberty, in a valuable written intervention) suggested that the formulation was deficient in omitting reference to an overriding requirement which featured in the judgment of Dickson CJ in R v Oakes[1986] 1 SCR 103 , from which this approach to proportionality derives. This feature is (p 139) the need to balance the interests of society with those of individuals and groups. This is indeed an aspect which should never be overlooked or discounted. The House recognised as much in R (Razgar) v Secretary of State for the Home Department[2004] UKHL 27 ,[2004] 2 AC 368 , paras 17-20, 26, 27, 60, 77, when, having suggested a series of questions which an adjudicator would have to ask and answer in deciding a Convention question, it said that the judgment on proportionality "must always involve the striking of a fair balance between the rights of the individual and the interests of the community which is inherent in the whole of the Convention. The severity and consequences of the interference will call for careful assessment at this stage" (see para 20). 20. In an article 8 case where this question is reached, the ultimate question for the appellate immigration authority is whether the refusal of leave to enter or remain, in circumstances where the life of the family cannot reasonably be expected to be enjoyed elsewhere, taking full account of all considerations weighing in favour of the refusal, prejudices the family life of the applicant in a manner sufficiently serious to amount to a breach of the fundamental right protected by article 8. If the answer to this question is affirmative, the refusal is unlawful and the authority must so decide. It is not necessary that the appellate immigration authority, directing itself along the lines indicated in this opinion, need ask in addition whether the case meets a test of exceptionality.”
