Can a variation of an interim order be made in the context of a motion to change a final order?

In the Innocente v. Innocente case, the issue was whether the court had jurisdiction to make an interim variation of a final order and whether or not a variation of an interim order (made in the context of a motion to change a final order) could be made. In that case, I concluded that, although variation of interim orders should be an infrequent event, available only (i) to prevent undue hardship; (ii) to prevent incongruity or absurdity, and (iii) where there is a pressing and immediate urgency), “it is not beyond the jurisdiction of a Superior court, where the circumstances justify it.” (para.55)
