The Independent Workers' Union of Great Britain has applied for a judicial review of a ruling that Deliveroo couriers are not employees, reports the Independent. Last year, the human cloud food courier firm won a landmark legal victory over the employment status of its drivers with the Central Arbitration Committee ruling that its riders were self-employed contractors and not employees. The union applied to the High Court for permission to have the ruling reviewed on the grounds that the Committee incorrectly interpreted the law. Deliveroo's rider contract allows couriers the right to find a substitute to do their deliveries which the court agreed was genuine. However, the union alleges that no evidence was heard during the tribunal of the substitution clause being correctly used. “This judicial review is about rectifying the situation and forcing Deliveroo to treat its riders as the workers they are,” union general secretary, Jason Moyer-Lee, said.
