London's Ultra-Low Emission Zone (Ulez) faces uncertainty as a recent ruling deems signs for its expansion unlawful. A tribunal overturned fines for a business owner, citing unclear charges on existing low emission zone signs. On the eve of Ulez's capital-wide expansion, the decision challenges the legitimacy of the signage. Despite Mayor Sadiq Khan's assertion that Tuesday marks a "landmark day" for Ulez, criticism persists over the scientific basis of pollution-related claims. The expansion, affecting all 32 boroughs, imposes a £12.50 daily charge on non-compliant vehicles. Noel Willcox, the business owner, successfully argued that signs did not comply with charging warnings, leading to the cancellation of fines. The ruling may impact future appeals against Ulez fines, with experts suggesting it could be used as persuasive evidence. While TfL claims the signs were deemed lawful by the Department of Transport in 2008, questions arise as to why evidence supporting this was not submitted during the appeal. The news surfaces as neighboring councils, except one, withhold support for Ulez, potentially providing drivers with grounds to appeal fines due to insufficient signage notice on roads into London. TfL is investigating the oversight.
