On 7 August 2024, the High Court of Australia handed down its long-awaited decision in Tesseract International Pty Ltd v Pascale Construction Pty Ltd [2024] HCA 24. The dispute arose out of a domestic commercial arbitration seated in South Australia, where the Commercial Arbitration Act 2011 (SA) is the relevant lex arbitri. That Act is a domestically focused adaptation of the UNCITRAL Model Law on International Commercial Arbitration (with its 2006 amendments).

The respondent to the arbitration sought to rely upon proportionate liability legislation found in the Law Reform (Contributory Negligence and Apportionment of Liability) Act 2001 (SA) and in the Competition and Consumer Act 2010 (Cth). The High Court was asked to determine whether those proportionate liability regimes could be applied in the arbitration. A very practical difficulty arose here, reflected in Steward J noting (in dissent) that the High Court was ‘faced with an invidious choice’: see [228]. Were the proportionate liability laws not to apply in the arbitration, the respondent might find themselves liable for 100% of the applicant’s loss, when they would not be liable to that same extent in court proceedings applying the same body of South Australian law. But were the proportionate liability laws to apply, the applicant might find themselves able to recover only a portion of their loss in the arbitration, and might then have to then pursue court proceedings against another third party wrongdoer to recover the rest: given that joinder is not possible in arbitration without consent.
