In paragraph 52 the Court quoted Lord Bingham's chapter on the exercise of power: "Ministers and public officers at all levels must exercise the powers conferred on them in good faith, fairly, for the purpose for which the powers were conferred, without exceeding the limits of such powers and not unreasonably". It added the principle that statutory power conferred for public purposes is held upon trust and may be used only in the way Parliament intended. A ministerial direction therefore cannot replace the judgment of the authority to which the statute gives the power.
