The International Court of Justice at the Hague could make a landmark decision on whaling.
It will decide whether Japan's annual whale hunt breaks international law.
Last June, Australia’s government launched a case against Japan, arguing that the country's scientific whaling is actually commercial and, therefore, breaks an international moratorium on whaling.
Japan argued that the court does not have the jurisdiction to decide what is or is not scientific whaling.
For eight months, the court has been considering whether Australia or Japan is right and will release its decision on Monday.
