4. The applicants now seek special leave to appeal from the decision of the Full Court and a stay of the order made by Beaumont J. Mr Bennett, who appeared for the applicants, developed two main submissions. First, he submitted that the actions of the Commonwealth Government, done under the prerogative towards other states or international organizations pursuant to a treaty, are not amenable to judicial review of any kind and that, as a corollary, there can be no obligation to accord natural justice before such action is taken and there can be no legitimate expectation that consultation will take place or that the interests of particular persons will be taken into account before such action is taken. Secondly, he submitted that the respondents would not suffer any material detriment if the areas were listed because under the Convention the listing would have no effect on the obligations of the Commonwealth and under the World Heritage Properties Conservation Act 1983 (Cth) the listing would have no operative effect, although the making of the submission would fulfil one of the conditions precedent to the making of a proclamation under s.6 of the Act, and the effect of such a proclamation would be, inter alia, to render it unlawful for the respondents to carry out mining operations on the land without the consent of the Minister (see s.10). He further contended that on an application for an interlocutory injunction it is the duty of the Court finally to determine any question which is one of law, rather than to inquire whether there is a serious question to be tried. Finally, in relation to the question of detriment, he pointed to material which showed that for Australia to seek to defer or withdraw its submission to the World Heritage Committee would have a potential seriously to embarrass Australia and would deleteriously affect Australia's high reputation with international environmental and heritage bodies and would call into question present and future Australian nominations to the World Heritage List. He said further that if the submission is not considered by the World Heritage Committee at its present sitting, it will probably not be considered for another twelve months, since the Committee meets only once a year.
