Steinlager is NZ's best selling beer and is brewed by Lion Nathan.But the World Intellectual Property Organisation, a division of the United Nations, has backed Lion Nathan's claim that the web address was not being used for business purposes. The Waughs had offered to sell the address for $20,000.According to the UN panel the Waughs had "no rights or legitimate interests in respect of the domain name." The Waughs, who own an electrical shop, claimed they used the site to sell components to road-marking companies in the US.David Asia-Pacific correspondent
