Hon MICHAEL WOOD: I always value the advice provided by Government departments, including Treasury, but, no, I don't always agree with them, and the job of Ministers is to consider that advice and then to make considered decisions, and that's what we've done in this case. I note that the formal advice that was presented to Cabinet through the indicative business case, provided by the light rail unit, which went through a Treasury gateway process, showed that all of the options before us—including the one that we have selected—have positive strategic cases, positive economic cases, a positive business case, and a positive benefit-cost ratio.
