Abolishing irrationality: a decision so unreasonable that no reasonable judiciary could ever come to it?

Abstract

ABSTRACT Much ink has been spilt over the workings of irrationality review and its continuing relevance. Absent in large part, however, is an examination of these issues situated outside the English context. This article seeks to fill that gap from a Singaporean perspective. It will be argued that, as a ground of review, the principle of rationality is amply adequate, and that its retention as part of Singaporean administrative law allows for an articulation of our own approach towards judicial review. The observations and arguments made therein may be of interest to other common law jurisdictions which find themselves at a crossroads.
