Response

A.

Exemptions and refusals applied to this response

Regulation 2 (1) of the Freedom of Information (Costs) (Jersey) Regulations 2014 allows an authority to refuse a request for information where the estimated cost of dealing with the request would exceed the specified amount of the cost limit of £500. This is the estimated cost of one person spending 12.5 working hours in determining whether the department holds the information, locating, retrieving and extracting the information. To answer this question as specified would take more than 12.5 hours of work; therefore the department is unable to provide the answer to this question.

B.
