Opportunity to be heard
25 Mr Ashby submits that even if there had been no delay, the reopening sought is not one upon which it can be said that Mr Slipper has not had the opportunity to be heard or is not at fault because he was expressly on notice of Mr Ashby's application for costs.
26 It is the case that costs, both of the primary proceedings and the appeal, were sought in the draft notice of appeal. However, Mr Ashby's written submissions of 3 April 2013 did not develop the application for costs, stating only that he wished to be heard "on the question of the appropriate costs order to be made in relation to both of the application for leave, the appeal and the costs below": para [104]. His written submissions did not mention or address s 570 of the FWA. During the hearing of the appeal, his senior counsel said nothing about the question of costs, and did not mention s 570 of the FWA.
27 By contrast, in Mr Harmer's application for leave to appeal (NSD 31 of 2013) counsel for Mr Harmer submitted that his client should have his costs if his application was successful, although even then s 570 of the FWA was not mentioned. Senior counsel for Mr Slipper responded to this submission by saying "… may I remind your Honours that this is a matter to which the Fair Work Act applied … and section 570 of that Act comes into play and that would require separate and detailed consideration on the question of costs". No response was made to this submission, other than to acknowledge it. This was the only mention of s 570 of the FWA by either party in written or oral submissions throughout the hearing of the appeal.
28 Mr Ashby carried the burden in relation to s 570(2) of the FWA. He advanced no submission of substance beyond an unparticularised application for costs. We accept that at the conclusion of the hearing of the appeal, Mr Slipper was entitled to assume that he was not at immediate risk of orders for costs against him, in that Mr Ashby's application for costs would not be pursued at all, or would only be pursued at a later stage of the proceedings.
29 We consider that, in substance, Mr Slipper has not been heard in relation to the costs awarded against him, both of the primary proceedings and of the appeal: Wentworth v Woollahra Municipal Council (1982) 149 CLR 672 at 684; Autodesk at 302.
30 The applicant submits that the respondent must demonstrate that the Court proceeded according to some misapprehension of the facts or the relevant law. The applicant relies on Grimaldi at [773]; De L at 215; Geraldton Port Authority at [20].
