“ This, however, does not settle the issue. Not only must a measure depriving a person of his property pursue, on the facts as well as in principle, a legitimate aim “in the public interest”, but there must also be a reasonable relationship of proportionality between the means employed and the aim sought to be realised…This latter requirement was expressed in other terms …by the notion of the “fair balance” that must be struck between the demands of the general interest of the community and the requirements of the protection of the individual’s fundamental rights. ” [§50] The ECtHR continued: “ The requisite balance will not be found if the person concerned has had to bear “an individual and excessive burden ”.

“Now there are old cases which show that the court can interfere by certiorari if a punishment is altogether excessive and out of proportion to the occasion … It is quite wrong that the Barnsley Corporation should inflict upon [Mr Hook] the grave penalty of depriving him of his livelihood. That is a far more serious penalty than anything the magistrates could inflict. He is a man of good character and ought not to be penalised thus. On that ground alone, apart from the others, the decision of the Barnsley Corporation cannot stand.”
