Administrative and Constitutional Law in UK Law

The most fundamental of all human rights is the individual's right to life and when an administrative decision under challenge is said to be one which may put the applicant's life at risk, the basis of the decision must surely call for the most anxious scrutiny.

First, the doctrine of proportionality may require the reviewing court to assess the balance which the decision maker has struck, not merely whether it is within the range of rational or reasonable decisions. Secondly, the proportionality test may go further than the traditional grounds of review inasmuch as it may require attention to be directed to the relative weight accorded to interests and considerations.

But where Parliament has conferred on the executive an administrative discretion without indicating the precise limits within which it must be exercised, to presume that it must be exercised within Convention limits would be to go far beyond the resolution of an ambiguity.

Judicial review has I think developed to a stage today when without reiterating any analysis of the steps by which the development has come about, one can conviently classify under three heads the grounds upon which administrative action is subject to control by judicial review. The first ground I would call "illegality," the second "irrationality" and the third "procedural impropriety."

By "irrationality" I mean what can by now be succinctly referred to as "Wednesbury unreasonableness" ( Associated Provincial Picture Houses Ltd. v. Wednesbury Corporation [1948] 1 K.B. 223). It applies to a decision which is so outrageous in its defiance of logic or of accepted moral standards that no sensible person who had applied his mind to the question to be decided could have arrived at it.

The giving of weight to factors such as these is not, in our opinion, aptly described as deference: it is performance of the ordinary judicial task of weighing up the competing considerations on each side and according appropriate weight to the judgment of a person with responsibility for a given subject matter and access to special sources of knowledge and advice.

But there are many cases where, although the tribunal had jurisdiction to enter on the enquiry, it has done or failed to do something in the course of the enquiry which is of such a nature that its decision is a nullity. It may in perfect good faith have misconstrued the provisions giving it power to act so that it failed to deal with the question remitted to it and decided some question which was not remitted to it.
