The question of whether a public authority can seek to rely on exemptions at a late stage in proceedings is one which arises in many tribunal appeals. Certainly, it is not at all unusual for a public authority to argue before the tribunal that it now wants to rely on exemptions which have never previously been identified. Historically, the Tribunal has taken the view that it has a discretion to refuse late reliance on exemptions and, in practice, it has tended to refuse late reliance save where there are exceptional circumstances (see further earlier paper on this issue which you can find here and see also an earlier post here). However, one tribunal has very recently taken a rather different view of the matter. In particular in Home Office v IC (EA/2010/0011), the tribunal held that in fact it had no discretion to refuse late reliance, particularly in view of the way in which the exemptions had been provided for under FOIA. This departure from tribunal orthodoxy is no doubt going result in a significant amount of debate, not least because there are now competing tribunal decisions on the issue of late exemptions. It may be that the matter will be resolved as and when the appeal in the case of DEFRA v IC & Birkett is heard in the Upper Tribunal. However, this remains to be seen. So watch this space.
