A "suck it and see" approach to the uncertainties of seabed mining is not good enough and is illegal - and that's the essence of an appeal to the High Court.
Kiwis Against Seabed Mining (KASM) is appealing the Environmental Protection Authority (EPA) decision to allow Trans Tasman Resources to mine ironsand from the South Taranaki seabed.
KASM's appeal to the High Court is on 15 points of law, new chairwoman Cindy Baxter said. One of them is that the EPA's many conditions amount to an adaptive management approach.
Adaptive management is about changing the way an activity is managed in response to as-yet-unknown effects. KASM's lawyers say such an approach is prohibited under government's exclusive economic zone (EEZ) legislation.
Another point KASM wishes to appeal on is the EPA's failure to impose a bond on the mining company. And it says the decision makers failed to apply caution and environmental protection or to take cumulative effects into account.
