Hon JAMES SHAW (Minister for Climate Change): Thank you, Madam Chair. I just wanted to ask the Minister for the Environment a question about clause 19, "Whether project helps to achieve purpose of Act". Before I asked the Minister about how Part 2 of the Resource Management Act was being reflected in the decisions of the panel; this one is more at the upfront stage when the Minister is choosing to refer something up to a panel. The second line says, "the Minister may have regard to the following matters, assessed at whatever level of detail the Minister considers appropriate," and then there's a whole series of things there—which are great. But I just wanted ask about the effect of the word "may" as opposed to "must"—the level of discretion that the Minister has about whether or not to pay attention to those kinds of environmental and other considerations.
