A Federal Court in Australia has ordered K-Line to pay an AUS $34.5m ($23.4m) fine after convicting the Japanese carrier of operating a criminal cartel in its car transportation business.

The court said K Line was operating together with other carriers in fixing prices to transport cars, trucks and buses to Australia between 2009 and 2012.

K Line had pleaded guilty to the charges in April last year following an investigation by the Australian Competition and Consumer Commission (ACCC).
