The proposed gas hub at James Price Point is not having an easy ride. In April, Woodside Petroleum shelved the project (the company recently announced it would instead develop the Browse basin offshore), and now the Supreme Court has found that decisions relating to environmental approvals -- including a decision by the Minister for the Environment that the project could go ahead -- were unlawful and invalid.

So, other than embarrassment for the government and the Environmental Protection Authority, what does all this mean?
