Campaigners against the ban on XL bully dogs have been granted permission to bring their legal challenge against the government to the High Court. The ban was introduced in October 2022, making it a criminal offense to own an XL bully dog without an exemption certificate. However, campaigners argue that the ban is unlawful and irrational, as it was based on unreliable material and lacked proper analysis of its impact. They also claim that the standards used to define an XL bully dog are vague and could lead to people unknowingly committing a criminal offense.
