If the Secretary of State is satisfied (either on a complaint by any person or otherwise) that a body to which this section applies have acted or are proposing to act unreasonably with respect to the exercise of any power conferred or the performance of any duty imposed by or under this Act, he may give such directions as to the exercise of the power or the performance of the duty as appear to him to be expedient (and may do so despite any enactment which makes the exercise of the power or the performance of the duty contingent upon the opinion of the body).

This section is subject to sections 508I and 509AE (complaints about transport arrangements etc).
