Ms LEY (Farrer—Deputy Leader of the Opposition) (14:00): My question is to the Minister for Indigenous Australians. Moments before question time, the Australian and the Bunbury Herald reported that Professor Marcia Langton, a member of the referendum working group appointed by the minister, has accused 'no' voters of opposing the referendum because of 'base racism' or 'sheer stupidity'. Will the Minister for Indigenous Australians condemn Professor Langton's comments? Honourable members interjecting— The SPEAKER: Order! Members on my left and the minister for the environment will cease interjecting so I can hear from the Leader of the House on a point of order. Mr Burke: On page 554 of Practice, there's a prevention of, or a ruling as out of order, questions that ask for ministers to comment on 'statements by people outside the House'. The SPEAKER: I'll hear from the Manager of Opposition Business. Mr Fletcher: Professor Marcia Langton is a member of the referendum working group appointed by the Minister for Indigenous Australians. A minister can be questioned on the following: 'matters for which he or she is responsible or officially connected', public affairs or administration. This appointment is the minister's appointment. The SPEAKER: I'll deal with this matter. Practice says 'statements by people outside the House including other members, notably opposition members, and senators'. I'll allow the question and I'll just ask the minister to make sure she's being relevant.
