The complainant has requested information associated with reconsideration hearings. Transport for London (TfL) refused to comply with the request which it categorised as vexatious under section 14(1) of the FOIA. TfL has subsequently confirmed that, notwithstanding its reliance on section 14(1), it considers the requested information is exempt from release under section 31(2)(c) (law enforcement) and section 40(2) (third person personal data). The Commissioner’s decision is as follows: The request is not vexatious and does not engage section 14(1). The information that has been requested is exempt from release under section 31(1)(g) leading to 31(2)(c), as disclosure would be likely to prejudice TfL’s regulatory functions. The public interest favours maintaining this exemption. TfL did not breach section 16(1) with regard to the advice and assistance it provided to the complainant. The Commissioner does not require TfL to take any steps.
