(d) Duty and liability — our reading

Liability indicators (our reading): none

Duty
Freedom of Information Act 2000 s.1 and s.10 (confirm or deny, and supply held information within 20 working days); Environmental Information Regulations 2004 for land and environmental records; records management under the s.46 Code of Practice; Public Records Act 1958 selection and transfer for central government records.
Indicators the duty was not met
none found in the correspondence on file.
Evidence still needed to confirm
the institution’s retention schedule and disposal record for the series in question; the catalogue or file list it searched; any internal review or complaint outcome.
Likely extent of exposure if confirmed
An ICO decision notice or a records-management finding; any reparations claim would also need a link between a records failure and the loss.
