New Zealand's top court on Friday left open the possibility that a man could be extradited to China to face murder charges in a landmark case that has big diplomatic implications. It remains uncertain whether the extradition of Kyung Yup Kim will proceed in a case that has already dragged on for more than a decade. The dispute hinges on whether New Zealand can be assured that Kim will get a fair trial if he's sent to China and won't be tortured. New Zealand doesn't have an extradition treaty with China.
