Dear Mr Butcher, 
1. 
I am writing to follow up my e-mail of 21 April in response to your’s of 25 March in which you 
requested:  
“Please list, for all meetings since 1992, the date, title and purpose of all JOWOGs and SUBWOGs 
meetings that have been held under the 1958 Mutual Defence Agreement between the United 
States and United Kingdom”
  
 
2. 
This letter is to inform you that the Ministry of Defence (MOD) holds information on the 
subject you have requested.  It has been assessed that the costs for which we are permitted to 
charge in providing this information will exceed the appropriate limit. This appropriate limit is 
specified in regulations and for central government is set at £600.  This represents the estimated 
cost of one person spending 3 and a half working days in determining whether the Department 
holds the information, and locating, retrieving and extracting the information.  Science and 
Technology Corporate Support has estimated that in order to retrieve the documents that you have 
requested would cost in excess of the £600 limit. Under the terms of Section 12 of the FOI Act, this 
means that we are not obliged to comply with your request. We have over 40 boxes of files on the 
subject relating to your request and to go through all of these would take approximately 60 working 
days.  However, should you refine your request for the information requested it is likely to fall within 
the scope of the following qualified exemption(s):  Section 24 [National Security] and Section 27 
[International Relations]. 
 
3. 
Your request is for information on the exchange mechanisms for the 1958 Mutual Defence 
Agreement. You may not be aware but a similar question was asked in Parliament by Mr Nick 
Harvey MP and was answered by the Secretary of State for Defence on 27 February 2009 (Official 
Report, Column 1149W). This was followed up by a further question on the subject by the same MP 
which also was answered by the Secretary of State for Defence on 23 March 2009 (Official Report, 
Column 17W).  The following extracts from the Official Report confirm the replies given:    
 
Hansard, 27 February 2009 - Official Report, Column 1149W. 
 
Nick Harvey: To ask the Secretary of State for Defence what the date was of each meeting of the

Mr. Hutton: I refer the hon. Member to the answer I gave him on 27 February 2009, Official Report, 
column 1149W. In the interests of national security I am withholding further information on the 
nature or extent of work undertaken by these Joint Working Groups

 
4. 
Some information on the 1958 Mutual Defence Agreement is already available in the public 
domain and is therefore exempted from release under Section 21 of the FOI Act – “Information 
accessible to the applicant by other means.” For example, information can be found on the following 
websites:  
www.nationalarchives.gov.uk/
www.energy.gov/

5. 
If you are not satisfied with this response or you wish to complain about any aspect of the 
handling of your request, then you should contact me in the first instance. If informal resolution is 
not possible and you are still dissatisfied then you may apply for an independent internal review by 
contacting the Head of Corporate Information, 6th Floor, MOD Main Building, Whitehall, SW1A 2HB 
(e-mail [email address]). Please note that any request for an internal review must be made within 
40 working days of the date on which the attempt to reach informal resolution has come to an end. 
 
6. 
If you remain dissatisfied following an internal review, you may take your complaint to the 
Information Commissioner under the provisions of Section 50 of the Freedom of Information Act. 
Please note that the Information Commissioner will not investigate your case until the MOD internal 
review process has been completed. Further details of the role and powers of the Information 
Commissioner can be found on the Commissioner's website, http://www.ico.gov.uk. 
 
Yours sincerely,  
Richard John
