The test laid down in this case, in all three limbs, is known as "the
Wednesbury test". The term "
Wednesbury unreasonableness" is used to describe the third limb, of being so unreasonable that no reasonable authority could have decided that way. This case or the principle laid down is cited in United Kingdom courts as a reason for courts to be hesitant to interfere with decisions of
administrative law bodies. In recent times, particularly as a result of the enactment of the
Human Rights Act 1998, the judiciary has receded from this strict abstentionist approach, arguing that in certain circumstances it is necessary to undertake a more searching review of administrative decisions. The
European Court of Human Rights requires the reviewing court to subject the original decision to "anxious scrutiny" as to whether an administrative measure infringes a Convention right. In order to justify such an intrusion, the Respondents have to show that they pursued a "pressing social need" and that the means employed to achieve this were proportionate to the limitation of the right. The UK courts have also ruled that an opinion formed by an employer or other contracting body in relation to a contractual matter has to be "reasonable" in the sense in which that expression is used in
