Australian Prime Minister Kevin Rudd bluntly told Japan today to stop hunting whales or face international court action this year, just a day before a visit by Foreign Minister Katsuya Okada.Rudd told the Channel 7 TV station that Australia would "work with the Japan to reduce, through negotiation, their current catch to zero". If that fails, Australia will initiate court action before the commencement of the whaling season in November 2010.
