TfL Ref: FOI-2339-2425

Thank you for your request received by Transport for London (TfL) on 21 October 2024 asking for information about the calibration records of the specified cameras. 

Your request has been considered in accordance with the requirements of the Freedom of Information (FOI) Act and our information access policy. I can confirm that we hold the information you require. 

Please find attached copies of the latest calibration certificates. 

In accordance with TfL’s obligations under Data Protection legislation, some personal data has been redacted, as required by section 40(2) of the FOI Act. Disclosure of this personal data would be a breach of the legislation, specifically the first principle of Article 5 of the UK General Data Protection Regulation which requires all processing of personal data to be fair and lawful. It would not be fair to disclose this personal information when the individuals have no expectation it would be disclosed and TfL has not satisfied one of the conditions which would make the processing ‘fair’.

This exemption to the right of access to information is an absolute exemption and not subject to an assessment of whether the public interest favours use of the exemption. 

The information you have requested regarding the maintenance or malfunctions of these cameras is exempt from disclosure under section 31 of the FOI Act, which can apply where release of information would be likely to prejudice the prevention of crime, or to prejudice the apprehension or prosecution of offenders. This is because the release of this information (or similar information in relation to other areas) would reveal locations where enforcement activity is less likely to be implemented and may therefore encourage people to ignore restrictions at those locations. Whilst we make no suggestion that you would use this information for anything other than your own interest, the disclosure of information under FOI is regarded as a disclosure to the public at large.

The use of this exemption is subject to an assessment of the ‘public interest test’ to determine whether the greater public interest rests in the exemption applying and the information being withheld, or in releasing it in any event. We recognise the need for openness and transparency by public authorities and the fact that you have requested the information is in itself an argument for release. However, in this instance we feel that the balance of public interest lies in favour of withholding the information to ensure that we are able to manage traffic on the TfL Road Network. It would be strongly against the public interest to release any information that would undermine this. We consider that the release of this information would lead to increased traffic problems as some motorists may seek to take advantage of the information, which would have a detrimental effect on street management. 

If you are unable to access these documents for any reason, please do not hesitate to contact me.

Please see the attached information sheet for details of your right to appeal. 

Yours sincerely,

Mary Abidakun
