I want to know the answer to the following question:
What court ruled the claim of climate change refugee to be untenable?
All the background I'm provided with is that "In 2014 attention was drawn to an appeal to the New Zealand Immigration and Protection Tribunal against the deportation of a Tuvaluan family on the basis that they were "climate change refugees", who would suffer hardship resulting from the environmental degradation of Tuvalu.". Is that enough to answer the question?
Answer: no
