But my colleague Simeon Brown actually related some of the history of it, and I think it's important in this third reading to go over that a little. There was an opportunity in this debating chamber to pass a piece of legislation that was brought to the House in a member's bill by my former colleague Alastair Scott. Now, that piece of legislation was almost identical in form to this piece of legislation, but for petty, party-political reasons it was voted down by the then Labour - Greens - New Zealand First administration. And they voted it down knowing, knowing then, that the science was unequivocal in terms of providing absolute evidence that drug testing, saliva testing, random saliva drug testing of this sort lowered the fatalities on our roads. We know that to be true because, in jurisdictions like Australia and in the United Kingdom, legislation of this sort had been in place for years with very effective results.
