They argued against the £12.50 daily fee for driving non-compliant vehicles in the expanded ULEZ. However, they lost the case in the High Court, and as a result, Hillingdon Council has been ordered to pay £147,000 in court costs.
Surrey County Council has also confirmed its costs for the challenge, which amount to £139,528.20, including a contribution to Transport for London's costs.
Justice Jonathan Swift, in his judgment, ruled that the Mayor had the lawful power to expand the ULEZ and that the information provided during the public consultation was sufficient. He also stated that the consultation question on the scrappage scheme, which offers grants to Londoners with non-compliant vehicles, was appropriately formulated.
Despite the loss in court, the anti-ULEZ coalition expressed pride in standing up for residents and businesses in their challenge against the ULEZ expansion.
