Senator BOB BROWN (Tasmania—Leader of the Australian Greens) (14:26): Mr President, I ask a further supplementary question. Was Mr Warburton on the board of Note Printing Australia from 2002 to 2009 when in mid-2007 that board was given information dealing with how the company's agents were bribing officials in Malaysia and Nepal but decided to take no action for pragmatic and legal reasons? Is the minister aware of any extenuating circumstances which allowed Mr Warburton and that board to take no action at that time? Opposition senators interjecting— The PRESIDENT: When there is silence we will proceed. Order! Again, the minister can only answer those parts of the question that relate to the portfolio.
