I recently put an FOI request into UEA asking for minutes of meetings of the Tyndall Centre Advisory Board - readers may remember that Tyndall was involved in the plan to get sceptics cleared from the airwaves, apparently at the instigation of the BBC's Roger Harrabin.
The university's acknowledgement of the request seems to flag fairly clearly how they intend to avoid disclosing anything embarrassing:
If the information you request contains reference to a third party then they may be consulted prior to a decision being taken on whether or not to release the information to you. You will be informed if this is the case.
The legislation provides exemptions for information provided in confidence and for personal information. I don't recall anything about consulting third parties.
