Key Facts
- •Four appellants challenged five decisions by the Information Commissioner regarding Transport for London's (TfL) refusal to disclose information about the make and model of CCTV and parking enforcement cameras.
- •Appellants argued that the Information Commissioner incorrectly applied the Environmental Information Regulations 2004 (EIR) instead of the Freedom of Information Act 2000 (FOIA).
- •TfL argued that disclosing this information would compromise public safety and national security due to a campaign of vandalism against ULEZ cameras.
- •The appeals involved numerous requests for information, some made before and after TfL's internal review clarifying its position on disclosure.
- •The Tribunal considered the 'mosaic effect', where seemingly innocuous individual pieces of information could be combined to reveal sensitive information.
