"38 Joining non-party concurrent wrongdoer in the action
(1) The court may give leave for any one or more persons to be joined as defendants in proceedings involving an apportionable claim.
(2) The court is not to give leave for the joinder of any person who was a party to any previously concluded proceedings in respect of the apportionable claim."
10 While different in form, the requirements for proportionate liability under the Trade Practices Act and/or the ASIC Act are similar.
Principles
11 The provisions of ss 56, 57, 58 and 59 of the Civil Procedure Act 2005 affect the exercise of jurisdiction to make any order or direction for the management of proceedings before the Court and, to the extent relevant, inform the exercise of any discretion of the Court in relation to the principles of case management and the balancing of justice between the parties.
12 Proportionate liability claims, apart from the delay that may be caused by any amendment to pleadings, will not, generally, prejudice a plaintiff, except to the extent that any such claim would delay the proceedings and prolong the hearing.
13 If, as the legislature contemplates, a defendant is not wholly responsible for the damage caused to a plaintiff, and others are, it is appropriate that those others share the burden of such damages as may be awarded. The provisions of s 38 of the Civil Liability Act have the effect that, a plaintiff can, in circumstances where a defendant alleges the existence of concurrent wrongdoers and a limitation in liability proportionate to the extent to which the defendant is responsible, join the alleged concurrent wrongdoers as defendants to the proceedings. While this may make the proceedings more complicated and more expensive from the perspective of the plaintiff, any prejudice to the plaintiff created thereby can be overcome with appropriate orders for costs.
Principles - Proportionate Liability
14 The fundamental principle underpinning the promulgation of legislation permitting proportionate liability is that persons, who are one only of a number who have occasioned the same damage, should bear the damage proportionately to the number of persons who are responsible.
15 The obvious precondition to limiting liability, on the basis that others are also responsible for the damage, is to prove that those others have caused the damage and are legally responsible for it.
16 There is a complementary duty (s 35A of the Civil Liability Act, above) on the defendant, who invokes the provisions, to inform the plaintiff of relevant information on any person, who may be a concurrent wrongdoer, in default of which there are consequences in costs.
17 As seems obvious from the foregoing, the scheme extends protections that would otherwise be available by issuing a cross-claim. In order to utilise a cross-claim, a defendant must allege a cause of action by it against the cross-defendant. The proportionate liability provisions allow the defendant to allege a cause of action by the plaintiff against the concurrent wrongdoer. Such a right brings with it the correlative duty to specify, in the same way as if there were a cross-claim, the basis for proportionate liability and the basis for identifying a person as a concurrent wrongdoer.
18 It is essential, if these provisions are to operate appropriately, that any defendant be required to plead the proportionate liability defence in a manner that discloses the cause of action and damage in at least as detailed a manner as would be required of any initiating process for such a cause of action. The information should include:
