(2) A public authority shall (a) cause copies of all documents to which this section applies that are in use to be made available for inspection and for purchase by members of the public; (b) not later than 12 months after the date of commencement of this Act, cause to be published in the Gazette, a statement specifying the documents of which copies are, at the time of preparation of the statement, so available and the place or places where copies may be inspected and may be purchased; and (c) within 12 months after the date of first publication of the statement under paragraph (b) and thereafter at intervals of not more than 12 months, cause to be published in the Gazette, statements bringing up to date information contained in the previous statement or statements. (3) The public authority may not comply fully with paragraph (2)(a) before the expiration of 12 months from the date of commencement of this Act, but it shall, before that time, comply with that paragraph as far as is practicable. (4) This section does not require a document of the kind referred to in subsection (1) containing exempt information to be made available in accordance with subsection (2), but, if such a document is not so made available, the public authority shall, if practicable, cause to be prepared a corresponding document, altered only to the extent necessary to exclude the exempt information, and cause the document so prepared to be dealt with in accordance with subsection (2). (5) Where a public authority comes into existence on or after the date of commencement of this Act, subsections (2) and (3) shall apply in relation to that public authority as if the references in those subsections to the date of commencement of this Act were references to the date the public authority so comes into existence. 16
