19 Definitions - pt 2.5
In this part:
court includes arbitrator.
damage means loss of any kind (including loss of life, personal injury, damage to property and economic loss).
wrong means an act or omission (whether or not an offence) -
(a) that gives rise to a liability in tort in relation to which a defence of contributory negligence is available at common law; or
(b) that amounts to a breach of a contractual duty of care that is concurrent and coextensive with a duty of care in tort.
20 Each of several wrongdoers can be sued
(1) A judgment or decision against a person for damage caused by a wrong does not bar an action against someone else who is also liable for the same damage.
(2) However, if separate actions are brought in relation to the same damage -
(a) the total amount recovered in the actions cannot exceed the amount of damages awarded in the judgment or decision given first or, if that amount is amended on appeal, the amount as amended; and
(b) the plaintiff is only entitled to costs in the action for which judgment or decision is given first (including costs on appeal from the judgment or decision), unless the court considers there were reasonable grounds for bringing the actions separately.
21 Right of contribution
(1) A person (the first person) who is liable for damage caused by a wrong can recover contribution from someone else (a contributory) who is also liable for the same damage.
(2) The contribution must be an amount that the court considers just and equitable having regard to the extent of the contributory's responsibility for the damage.
(3) However, the first person is not entitled to contribution under this section if -
(a) the first person is liable to indemnify the contributory against the contributory's liability for the damage; or
(b) the court exempts the contributory from liability to make contribution; or
(c) the court has directed that contribution to be recovered from a person for the damage is a complete indemnity for the damage.
