(3) Subject to this section and to section 16(2), where the applicant has requested access in a particular form, access shall be given in that form. (4) If the form of access requested by the applicant (a) would interfere unreasonably with the operations of the public authority; (b) would be detrimental to the preservation of the document or having regard to the physical nature of the document, would not be appropriate; or (c) would involve an infringement of copyright subsisting in a person other than the State, access in that form shall be refused but access may be given in another form. 19. (1) A public authority which receives a request may defer the provision of access to the document concerned if the document has been prepared (a) for presentation to Parliament; (b) for release to the media; or (c) solely for inclusion, in the same or in an amended form in a document to be prepared for a purpose specified in paragraph (a) or (b), and the document is yet to be presented or released, or included in a document to be presented or released, as the case may be. (2) Where the provision of access to a document is deferred in accordance with subsection (1), the public authority shall, in forming the applicant of the reasons for the decision, indicate, as far as practicable, the period for which the deferment will operate. 20. (1) A public authority dealing with a request under this Part for access to documents, or an application under section 36 for the correction of personal information, may refuse to grant access to documents, or to correct information, in accordance with the request or application, without having caused the processing of the request or application to have been undertaken or at any later time, if the public authority is satisfied that (a) the request or application is made by, or on behalf of, a person who, on at least one previous occasion, has made a request or application to the public authority, or to a predecessor of the public authority, for access to the same documents or for the same correction; (b) the request or application was refused and the High Court, on reviewing the decision to refuse the request or application, confirmed the decision; and (c) there are no reasonable grounds for making the request or application again.
