18. Even if I was not functus officio, I would have significant doubts, in any event, about my capacity to make orders under s109(4). It seems to me that the power in s109(4) is, in effect, punitive or at least extraordinary and it is not one, in my view, which should be exercised except in cases which clearly fall within its terms fairly construed. Yet, it is limited to making orders against "the representative of a party". How, may I ask, may I make orders against Mr Ireland if he is no longer "the representative of a party"? But if, in some way, he is still "the representative of a party", namely, the Applicant, how might I now find that he is "responsible for conduct described in sub-section (3)(a) or (b)"? To do so, presumably I would need to revisit matters raised with me on 26 March when the costs order was made. But this would mean those matters would need to be re-agitated - for, I would think, Mr Ireland would be entitled to be heard on them (see ss97 and 98(1)(a) of the Act) - yet it cannot be proper in law to suggest that final orders, properly made and regularly entered, can be reviewed in this way. Final orders might not be final orders after all, if this were right. The possibility would be opened up also, on this analysis, that on 26 March I found the Applicant represented by Mr Ireland engaged in conduct under ss109(3)(a) and (b) whereas, upon a re-agitation of the same matters some 5 months later, I could now find Mr Ireland was not responsible for that conduct possibly because, at this later point, I could not be satisfied, having heard argument, that such conduct had taken place. This would be preposterous, and Parliament could not have intended to allow this to follow. It seems to me, then, that, if an order is to be sought under s109(4), it should be sought at the time when costs themselves are under consideration and not later. If something comes to light later, which means a costs order under s109(4) should have been applied for at the time, then the remedy, it seems to me, lies elsewhere.
