(5) Where a request is made to a public authority for access to a document that contains information of a medical or psychiatric nature concerning the person making the request and it appears to the public authority that the disclosure of the information to that person might be prejudicial to the physical or mental health or wellbeing of that person, the public authority may direct that the document containing that information, that would otherwise be given to that person is not to be given to him or her but is to be given instead to a medical practitioner to be nominated by that person. Documents relating to trade secrets, business affairs, etc. 32. (1) A document is an exempt document if its disclosure under this Act would disclose information acquired by a public authority from a business, commercial or financial undertaking, and (a) the information relates to trade secrets or other matters of a business, commercial or financial nature; or (b) the disclosure of the information under this Act would be likely to expose the undertaking to disadvantage. (2) In deciding whether disclosure of information would expose an undertaking to disadvantage, for the purposes of paragraph (b) of subsection (1), a public authority may take account (a) whether information is generally available to competitors of the undertaking; (b) whether the information would be exempt information if it were generated by a public authority; (c) whether the information could be disclosed without causing substantial harm to the competitive position of the undertaking; (d) whether there are any considerations in the public interest in favour of disclosure which outweigh considerations of competitive disadvantage to the undertaking, for instance, the public interest in evaluating aspects of regulation by a public authority of corporate practices or environmental controls; and 27
