Have you ever been in a position whereby you felt that a decision that was made by your Local Authority was downright unreasonable? Well, did you realise that there may have been something more that you could have done about it? Probably not, as most public bodies are hardly screaming such a thing from their rooftops.
Well, just after World War II, a case went as far as The House of Lords that was to change the English legal system from then on. It was from Associated Provincial Picture House v. Wednesbury Corporation [1948] and it came about when the local authority were trying to assert that a condition of granting the cinema a licence would be for them to exclude the attendance of children on Sundays.
Luckily, Lord Diplock completely disagreed with this condition and went on to state that it was definitely unreasonable. As a result and because this case was heard in the highest court of the land (at that time), this case became what is known as a legal precedent and a test for reasonability in the future for all public bodies to be subjected to. This test is now known as the Wednesbury Principle.
So, if you feel that a public body has arrived at a decision that any ordinary man in the street would believe to be unreasonable - you may very well have cause to pursue a judicial review against them. Just one piece of advice here, though: make sure you apply for the review as quickly as possible; there is a very limited timescale in which you can do so. Also, it would definitely be best to approach a legal professional that deals with administrative and constitutional law to assist you in this action.
