The legal battles culminated in a House of Lords ruling. The Law Lords ultimately sided with Critical Mass, stating that it did not fall under the definition of a procession requiring notification under the Public Order Act. The court’s decision recognized that Critical Mass, with its lack of designated organizers or a fixed route, was a recurring, loosely organized event, not subject to the notification requirements. This ruling clarified that participants in Critical Mass were not obligated to notify the police in advance, making the event lawful.
