in 1947, the corporation granted a licence for the operation of a cinema, on the condition that no children under 15 were to be admitted on sundays. the cinema operator challenged this decision in court, claiming that the imposition of the condition was outside the corporation's powers. the court used this case to establish a general test for overturning the decision of a public body in this type of case, which is now known as "wednesbury unreasonableness".
