The High Court has clarified that statutory proportionate liability regimes are applicable in arbitration proceedings, a development with significant implications for construction and commercial contracts. Tesseract International Pty Ltd v Pascale Construction Pty Ltd [2024] HCA 24 overturned the South Australian Court of Appeal’s earlier decision. The High Court confirmed that defendants can rely on proportionate liability even when third-party wrongdoers are not parties to the arbitration.
Proportionate liability limits a defendant’s responsibility to the extent of their contribution to the claimant’s loss. This places the burden of pursuing other concurrent wrongdoers onto the claimant, who may need to initiate separate proceedings or seek the joinder of third parties. The ruling departs from the traditional common law approach, under which a claimant could recover the full loss from one defendant, who would then be responsible for pursuing contributions from other wrongdoers if necessary.
This case arose from a dispute over engineering consultancy work performed by Tesseract International Pty Ltd, who argued that other parties shared responsibility for the losses claimed by Pascale. The High Court confirmed that proportionate liability provisions under the Competition and Consumer Act 2010 (Cth) can apply in arbitration, unless expressly excluded in the arbitration agreement.
