52.This states that an authority must comply with its duty under section 1 promptly and in any event within 20 working days (or other period, not later than 60 working days, set under regulations) from receipt of a request. If a fees notice is issued, time stops running from the issue of the notice until the fee is received. Working days do not include any Saturday or Sunday or Christmas Day, Good Friday or bank holidays under the Banking and Financial Dealings Act 1971 in any part of the UK. Where an authority is not able to reach a decision as to the balance of the public interest in disclosure within 20 working days, it must reach a decision within a reasonable period. In these circumstances, the authority is still required to issue a notice that an exemption applies under the provisions of section 17(1) within the 20 working day limit.
