Mason's account challenges the accuracy and completeness of Kerr's account in several respects, but most importantly on his advice regarding power to dismiss a Prime Minister. He confirms that as early as August 1975 he had advised Kerr, as a "close friend", that the Governor-General does have such power. He confirms, as Kerr's autobiography had stated although Kerr's papers give a different impression, that he had only advised Kerr on the available courses of action and had not advised him to pursue the course of dismissal.
