Blair & Murdoch, papers related to FoI enquiry about their meetings

Dear Sir or Madam,
I would like to see the documents which specify which out of the
five questions -
• Can the request be seen as obsessive?
• Is the request tantamount to harassing the authority or causing
distress to staff?
• Would complying with the request impose a significant burden?
• Is the request designed to cause disruption or annoyance?
• Does the request lack any serious purpose or value?
- drawn up by the Office of the Information Commissioner for
judging whether a FoI request might reasonably be judged
"vexatious" was deemed to justify refusing to release papers
generated by an earlier FoI request for the records of exchanges
between Tony Blair and Rupert Murdoch.

Yours etc.,
Michael McCarthy

Dear Sir or Madam,

If there exists any justification in the FoI Act for this implicit
refusal by the Cabinet Office to disclose, as requested, which of
the five admissible grounds for declaring an information request
"vexatious" was deemed to apply in my case, I invite you to cite
it. Otherwise, I expect you to respond to my question, as is my
right under the FoI Act, and specify precisely which of these five
grounds you propose to rely on.

Yours etc.
Michael McCarthy

Dear Sir or Madam,
I have been in contact with the Information Commissioner's Office,
and have been assured that there is no reason why I should not be
given clarification of the grounds on which an information request
is deemed "vexatious".

Presumably some specific ground, rather than the mere intent as
previously to stonewall a legitimate request, was in the mind of
someone at the Cabinet Office when this request was so deemed. If
so, kindly disclose it without further delay, and then we can all
judge how plausible it appears.

Yours etc.,

Michael McCarthy
