In most jurisdictions in Australia, a prospective plaintiff can obtain preliminary discovery orders from a Court to ascertain whether it has a right to obtain relief from a prospective defendant, before it commences any substantive proceeding.
This blog post explores the availability of preliminary discovery where parties are subject to arbitration agreements, drawing on recent judicial decisions to provide practical insights.
Generally, a prospective plaintiff may obtain preliminary discovery, if it can demonstrate that:
An interesting question arises where, before an arbitral tribunal is constituted, a party to an arbitration agreement seeks documents from a counterparty, to determine whether to initiate a case at all. Preliminary discovery may fill this gap.
For arbitrations seated in Australia, the general position is that a prospective plaintiff may seek preliminary discovery through domestic court procedures before commencing arbitration: see our earlier blog post.1 In summary:
In nearmap, Spookfish argued that the preliminary discovery application commenced in the NSW Supreme Court should be permanently stayed and instead decided by the arbitral tribunal pursuant to an arbitration agreement, citing s 8 of the Commercial Arbitration Act 2012 (WA) and s 8 of the Commercial Arbitration Act 2010 (NSW). Chief Judge in Equity Bergin refused to stay the Court proceedings, ruling that the preliminary discovery motion did not constitute a “matter” under these statutory provisions. Although nearmap concerned a domestic arbitration, its principles are likely also applicable to international arbitrations seated in Australia.
As a consequence, prospective plaintiffs who are parties to an arbitration agreement may seek preliminary discovery under domestic court procedures in Australia.
The recent NSW Supreme Court decision of Illawarra Basketball Club Pty Ltd v National Basketball League Pty Ltd also considered whether parties to an arbitration agreement could seek preliminary discovery from the Court.3
The Illawarra Hawks and South East Melbourne Phoenix (the Clubs) sought preliminary discovery to obtain documents from National Basketball League Pty Ltd (NBLCO).4 The NBLCO operates Australia’s National Basketball League (NBL). NBLCO sought to stay the Court proceedings in light of an arbitration agreement in the licence agreements between NBLCO and the Clubs.5 The relevant licence agreements contain an arbitration clause which provides for disputes to be arbitrated by the Court of Arbitration for Sport (CAS) in Switzerland.6
Justice Peden considered three possible avenues for a stay:
(i) s 7(2) International Arbitration Act 1974 (Cth) (“Act”)
As noted above, under section 7(2) of the Act, if Court proceedings involve a “matter” that is capable of being settled by arbitration, the Court must stay the proceedings and refer the parties to arbitration.
Her Honour found that an application for preliminary discovery was not a “matter” capable of being settled under the arbitration agreement because:
(ii) Article 8 of the UNCITRAL Model Law on the International Commercial Arbitration (“Model Law”) contained in sch 2 of the Act
This provision mirrors section 7(2) of the Act and for the same reasons above, the Court found it did not provide a basis for a stay of the proceedings.
(iii) Court’s inherent or general statutory power to order a stay
NBLCO argued that a stay should be granted nevertheless because the Clubs’ preliminary discovery application breached the contractual obligation to arbitrate and the contractual covenant not to sue (in clause 14.3 of the Licence Agreements). This argument relied on the Court exercising its inherent power to stay proceedings.
Clause 14.3 provides:
The parties agree that the [Grievance Procedure]…. shall be followed and that the decision of CAS shall be final and binding. It is further agreed that no party will institute or maintain proceedings regarding a Grievance or any other matter regarding this Agreement or their participation in the NBL in any court or tribunal other than CAS.
The Court ultimately ordered a stay of the preliminary discovery application under its inherent powers in section 67 of the Civil Procedure Act 2005 (NSW) on the following bases:
The judgement offers several key insights and practical considerations where a party to an arbitration seeks preliminary discovery:
