Senator BRANDIS (Queensland—Deputy Leader of the Opposition in the Senate) (14:17): Mr President, I ask a supplementary question. Does the minister recall actually chairing one of the four parliamentary inquiries that concurrently examined the GST legislation when he was the Chair of the Community Affairs References Committee? Does the minister believe the proposed single three-week parliamentary inquiry into the 19 carbon tax related bills will provide the same level of scrutiny that was applied over five months by four committees to the GST bills?
