(1) The Commissioner may from time to time approve, in relation to public authorities falling within particular classes, model publication schemes prepared by him or by other persons. (2) Where a public authority falling within the class to which an approved model scheme relates adopts such a scheme without modification, no further approval of the Commissioner is required so long as the model scheme remains approved; and where such an authority adopts such a scheme with modifications, the approval of the Commissioner is required only in relation to the modifications. (3) The Commissioner may, when approving a model publication scheme, provide that his approval is to expire at the end of a specified period. (4) Where the Commissioner has approved a model publication scheme, he may at any time publish, in such manner as he thinks fit, a notice revoking his approval of the scheme as from the end of the period of six months beginning with the day on which the notice is published. (5) Where the Commissioner refuses to approve a proposed model publication scheme on the application of any person, he must give the person who applied for approval of the scheme a statement of the reasons for his refusal. (6) Where the Commissioner refuses to approve any modifications under subsection (2), he must give the public authority a statement of the reasons for his refusal. (7) Where the Commissioner revokes his approval of a model publication scheme, he must include in the notice under subsection (4) a statement of his reasons for doing so.
