Judicial Review in English Law - Grounds For Review - Irrationality - Proportionality

Proportionality

Proportionality is a requirement that a decision is proportionate to the aim that it seeks to achieve. E.g. an order to forbid a protest march on the grounds of public safety should not be made if there is an alternative way of protecting public safety, e.g. by assigning an alternative route for the march. Proportionality exists as a ground for setting aside administrative decisions in most continental legal systems and is recognised in England in cases where issues of EC law and ECHR rights are involved. However, it is not as yet a separate ground of judicial review, although Lord Diplock has alluded to the possibility of it being recognised as such in the future. At present, lack of proportionality may be used as an argument for a decision being irrational.
