This information is exempt from disclosure under Section 31(1)(a) of the Freedom of Information Act - Law enforcement. Disclosure of this information would be likely to prejudice the prevention or detection of crime.
Section 31(1)(a) provides an exemption where prejudice could be caused to allow potential fraudsters to use the information to identify business entities or individuals which were entitled to claim credits on their accounts. Once such a business or individual had been identified, there would be a number of avenues open to the fraudsters to seek to obtain funds.
Disclosure of this information would result in the need to implement disproportionate steps and additional expense to the public purse to counter an increased fraud risk that does not exist at present and this information will therefore not be released.
