House of Assembly Fifty-Fifth Parliament, First Session (55-1) 55 1 Parliament of South Australia House of Assembly published Parliamentary Procedure Parliamentary Procedure Supplementary Questions Supplementary Questions The Speaker House of Assembly Kavel Minister for Police, Emergency Services and Correctional Services Special Minister of State The SPEAKER (15:13): Before I turn to the member for Heysen, I did not want to unduly delay us in question time earlier by providing a ruling on supplementary questions; however, it may assist. A supplementary question may refer only to the answer out of which it immediately arises, must relate to government responsibility, must not be read or be too long or quote from letters, should contain only one question, must not refer to an earlier answer or be addressed to another minister, and is governed by the general rules of order affecting all questions. That is the persuasive content of Erskine May.
