It seems to me that, in order that a person should be exempted from contribution, he must have been "sued to judgment" and found to be not liable. Those words "sued to judgment" were used by Parker J in Littlewood v George Wimpey & Co Ltd and BOAC and BOAC (Third Party) and were adopted by Morris LJ in the same case. When an action has been dismissed for want of prosecution, the defendant has not been "sued to judgment" at all. There has been no finding on the merits. There has been no judgment that the defendant is not liable. It is only an interlocutory order - a matter of procedure - which does not affect substantive rights. It is not a final decision. It does not give rise to an estoppel by res judicata. The plaintiff can start another action for the same cause, so long as he does so within the period allowed by the Statute of Limitations: see Magnus v National Bank of Scotland and Pople v Evans . Seeing that it is only a procedural matter, I hold that the defendant is not exempted by reason of the action being dismissed for want of prosecution. He is still liable to make contribution if he is a person who "would, if sued, have been liable, in respect of the same damage".
26 James Hardie & Coy Pty Ltd v Seltsam Pty Limited [1998] HCA 78; (1998) 196 CLR 53 was a case in which the injured plaintiff sued three defendants in the Dust Diseases Tribunal. The first defendant cross-claimed against the third defendant and the third defendant cross-claimed against the first and second defendants. Consent judgment was entered for the plaintiff against the first and second defendants and judgment was entered in favour of the third defendant. Before judgment was pronounced, counsel for the first defendant indicated that his client did not consent to judgment being entered for the third defendant on the main claim but expressed the view that he was not entitled to be heard further in relation to that matter. Counsel for the first defendant also submitted that entry of the judgment in favour of the third defendant on the main claim could not affect the first defendant's claim for contribution against the third defendant. The Judge agreed and indicated that he would hear the cross-claim in respect of contribution at a later time. Before that matter came on for hearing the third defendant obtained an order striking out the first defendant's claim for contribution.
27 Gaudron and Gummow JJ said at 66-67:
The claimant tortfeasor who satisfies the condition precedent may recover contribution from those other tortfeasors who bear responsibility in respect of the same damage in a fashion which answers a description in the balance of paragraph (c). The defendant tortfeasor must be one (i) "who is … liable in respect of the same damage" or (ii) "would if sued have been, liable in respect of the same damage". Only those who satisfy (i) or (ii) are amenable to a claim for contribution under the statute. Further, those who have been sued to judgement, whatever its outcome, do not fall within (ii). That is the effect of settled authority in this Court.
28 Gaudron and Gummow JJ then referred to Barwick CJ's statement in Brambles Constructions Pty Limited v Helmers referred to above and said at 68, [38] (footnotes omitted):
In Hart v Hall & Pickles Ltd , the English Court of Appeal held that, where the action by the victim of the tort against the defendant in the contribution proceeding has been dismissed for want of prosecution, that person answers the description of one who "would if sued have been, liable in respect of the same damage". This was because the phrase "if sued" was rendered inapplicable only if the tortfeasor in question had been sued to judgment and the dismissal for want of prosecution was but an interlocutory order.
29 Callinan J said at 96:
Lord Denning MR, although he said that there had been no judgment on the merits, added that the joint tortfeasor had "not been sued to judgment". His Lordship also referred to the interlocutory and non-substantive nature of a dismissal for want of prosecution which does not bar a further action based on the same facts.
30 Kirby J, in dissent, said at 79-80 and 85-86 (footnotes omitted):
70. The parallels between Hart and the present case, although not exact, are striking. Here too the person alleged to be a co-tortfeasor has been sued. Here too that action has been dismissed. The only difference is that here the action was dismissed not for want of prosecution by the plaintiff but by reason of a consent judgment between the plaintiff and the target tortfeasor to which the claimant tortfeasor, held liable, was not a party. In common with the present case and the situation in Hart there has been no holding of liability "on the merits of the case", a requirement thought necessary to secure the immunity in Lord Denning's third situation. …
71. Both the appellant and the respondent sought to derive support from Hart's case. The appellant laid emphasis upon the repeated references to the need for an action "to judgment" and a "finding on the merits" to warrant extinguishing the claimant tortfeasor's statutory right to contribution. The appellant also used the case to illustrate its argument that the statutory language was not narrowly confined. It had to be given meaning in a variety of circumstances. It invoked a true hypothetical suit, the outcome of which determined whether there would be recovery or not. On the other hand, the respondent argued that it had indeed been "sued to judgment" and that the judgment against it was not interlocutory but affected substantive rights as between it and the plaintiff so as to foreclose the preconditions necessary to the appellant's statutory claim for contribution. The Court below preferred the latter approach. But should we?

84. The words "would if sued have been" in par (c) therefore envisage a completed action where the target tortfeasor has been sued to judgment and the action has been fully dealt with on its merits. Lord Denning suggested this construction of the paragraph in Hart . Windeyer J implied as much in Brambles when he said:
"The description, a tort-feasor who if sued would have been liable, denotes any person who would have been held liable in tort had he been sued in a competent court, by proper process, at a proper time and on evidence properly presented - that is anyone whose liability as a tortfeasor could have been ascertained in an action."
85. Clearly, in the context, the ascertainment of liability means ascertainment on its merits, …
