California government code 6254 and this chapter does not require the disclosure of any of the following records:
(a)Preliminary drafts, notes, or interagency or intra-agency memoranda that are not retained by the public agency in the ordinary course of business, if the public interest in withholding those records clearly outweighs the public interest in disclosure.
(b)Records pertaining to pending litigation to which the public agency is a party, or to claims made pursuant to Division 3.6 (commencing with Section 810), until the pending litigation or claim has been finally adjudicated or otherwise settled.
(c)Personnel, medical, or similar files, the disclosure of which would constitute an unwarranted invasion of personal privacy.
