Severing the Judgment
71The appellant submitted that once the Court concluded that the default judgment had been given or entered irregularly, the judgment and any consequential orders made by the primary Judge should be set aside. Mr Pritchard SC, who appeared with Ms Nolan, contended that the irregularity was fundamental, in that the District Court simply had no power to enter a default judgment under r 16.6 since the pleaded claim was not for a liquidated sum. It followed, so he argued, that the appellant was entitled to have the judgment set aside ex debito justitiae : cf Cameron v Cole [1944] HCA 5; 68 CLR 571, at 579, 581 per Latham CJ. Mr Pritchard added that, in any event, there was no dispute that the appellant had an arguable defence in each aspect of the respondents' claim.
72Mr Horowitz did not dispute that the appellant, once the irregularity I have identified was established, was entitled to have the judgment for $260,467.60 set aside. However, as I have noted, he submitted that the judgment should be set aside only insofar as it related to the claim for the sum of $199,500, and not insofar as it related to the separate claim for the sum of $60,967.60. He contended that the latter claim, as pleaded, was for a liquidated sum and thus was severable from the first claim. Mr Horowitz accepted that the appellant had an arguable defence to the claim for $60,967.60. However, he pointed out that UCPR r 16.8(1) provides that:
"If the plaintiff's claim against a defendant in default includes any 2 or more of the claims referred to in this Part, and no other claim, judgment may be given for the plaintiff against the defendant on any of those claims as if it were the plaintiff's only claim for relief against that defendant."
73The default judgment obtained by the respondents was for a single amount. They did not rely on r 16.8 in order to distinguish between the two amounts said to be due by the appellant under the Separation Agreement.
74On the hearing of the appellant's motion in the District Court to set aside the default judgment, the respondents again did not distinguish between the two amounts claimed in the statement of claim. In particular, they made no submission that if the judgment for $260,467.60 was irregularly made, it should be set aside only to the extent of $199,500 and should remain on foot as to the balance. On the contrary, the application before the primary Judge was conducted by the respondents on the express basis that if her Honour concluded that the judgment had been made or entered irregularly, it had to be set aside in its entirety. The respondents' written submissions in this Court did not depart from the position they had adopted in the District Court. It was only in oral submissions that Mr Horowitz belatedly sought, in effect, to divide the judgment into two parts. He referred to r 16.8 in supplementary written submissions.
75In my opinion, there is a strong argument that the respondents should not be permitted to resile from the basis on which the District Court hearing was conducted. Because the issue was not raised in the District Court on the motion to set aside the judgment, no arguments were advanced as to whether the claim for $60,967.60 was for a liquidated sum or whether an irregularity in giving judgment for a single sum can be said to affect only part of the judgment. The respondents did not file or seek to file a cross-appeal or notice of contention in this Court: cf rr 50.10, 11. The issue only arose in oral argument on the appeal.
76In any event, I do not think that the respondents' argument should be accepted. The respondents applied for and were given default judgment for a single sum, in accordance with the case pleaded in the statement of claim. They did not seek a default judgment in respect of each of the amounts claimed in the statement of claim, as r 16.8 contemplates. They did not file an affidavit specifically addressing the claim for $60,967.60, as required by r 16.8(2).
77The appellant applied pursuant to r 36.15(1) to set aside the default judgment for $260,967.60 that the respondents had obtained. As I have explained, that judgment was given irregularly within the meaning of r 36.15(1). The Court's power to set aside the default judgment was therefore enlivened. In any event, the respondents did not comply with the requirements laid down by r 16.8(2) in respect of the claim for $60,967.60.
78To leave standing the default judgment to the extent of $60,697.60 would give the respondents the benefit of a default judgment which is affected by an irregularity. That is so whether the judgment is seen as for a single sum ($260,467.60) or for a portion of that sum, namely $60,697.60. Since the respondents accept that the appellant has an arguable defence to the claim for $60,697.60, I see no proper basis on which this Court should make orders her Honour was not asked to make.
