PEARLMAN'S CASE

Pearlman v Keepers and Governors of Harrow School [1979] QB 56 (CA): Lord Denning said that the distinction between an error which entails absence of jurisdiction, and an error made within the jurisdiction, ‘should now be discarded. …No court or tribunal has any jurisdiction to make an error of law on which the decision of the case depends. If it makes such an error, it goes outside its jurisdiction and certiorari will lie to correct it.’
