Canberra on Friday welcomed the International Court of Justice's decision Thursday to schedule three weeks of public hearings in The Hague from June 26 on Australia's case against Japan's so-called research whaling.

"We will now have our day in court to establish, once and for all, that Japan's whaling hunt is not for scientific purposes and is against international law," Attorney General Mark Dreyfus, who will represent Australia at the hearings, said in a statement.

"Australia wants this slaughter to end," he added.
