More than 6 000 taxi drivers and car-hire operators are suing Uber in Australia, signing on to a major class action lawsuit. The suit alleges that Uber defied regulations and operated illegally, giving it an unfair advantage over local taxi drivers and other industry players that complied with the law. CNN reports that Australian law firm Maurice Blackburn filed the case in the Victorian Supreme Court on Friday. ‘Uber sells the idea that it does things differently, but in reality and as we allege, this has meant operating unlawfully, using devious programmes like Greyball (a software programme that prevented regulators and law enforcement from monitoring Uber's app),’ said lawyer Elizabeth O'Shea.
