Section 8(1) of the Commercial Arbitration Act 2012 (WA) does not mandate a stay of proceedings commenced by non-parties to an arbitration agreement, even where the proceedings raise matters overlapping with the subject matter of the arbitration agreement. Section 5 of the Act does not prohibit the court from adjudicating on defences that raise issues overlapping with matters governed by an arbitration agreement where the proceedings are brought by non-parties. Where curial proceedings by non-parties overlap with arbitral proceedings, the risk of issue estoppels arising from findings in the curial proceedings is a factor favouring a stay, not a factor favouring refusal of a stay, but the weight of that factor depends on the contingency and uncertainty of the risk materialising.
