Mr. Woodworth pointed out exactly what needs to be said here, and that is that this is an interpretation clause. Actually, rather than focusing on just one of the clauses, we should probably develop the arguments and implications of each of them prior to approving clause 3. I think it's appropriate to talk about the implications and consequences of how sustainable development is seen throughout the whole act, and that's what Mr. Warawa has been doing.
Each of those things needs to be examined in detail in order to understand the implications for the act, and I don't understand why the opposition would object to that approach, unless there is some reason they don't want that examination done. I think we're completely appropriate here.
It says that the act must be interpreted consistently using these principles, and it would seem logical and reasonable to discuss the implications of those principles before we move ahead any further.
