CONSOLIDATION OF MULTIPLE DISPUTES IN COMMERCIAL ARBITRATION

In modern commercial practice, particularly in sectors such as construction, sale of goods, and provision of services, it is common for multiple disputes to arise simultaneously between the same parties or out of the same legal relationship. If such disputes are resolved separately, the parties may face increased procedural costs, prolonged proceedings, and even the risk of inconsistent arbitral awards.

In this context, the consolidation of multiple disputes into a single proceeding constitutes an important procedural mechanism in commercial arbitration. This mechanism allows related disputes to be combined and resolved within the same proceedings, thereby enhancing procedural efficiency and ensuring consistency in the resulting arbitral award.

1. Vietnamese Legal Framework for the Consolidation of Disputes

The Law on Commercial Arbitration 2010 does not contain explicit provisions governing the consolidation of multiple disputes within a single arbitral proceeding. However, this issue is addressed inResolution No. 01/2014/NQ-HĐTP of the Council of Judges of the Supreme People’s Court of Viet Nam.

Pursuant to Article 7(4) of this Resolution, the consolidation of multiple legal relationships in dispute into a single proceeding may be carried out where one of the following conditions is satisfied: (i) the parties have agreed to consolidation; or (ii) the applicable arbitration rules of the arbitral institution permit such consolidation.

This provision indicates that Vietnamese arbitration law implicitly recognises the mechanism of consolidation, while emphasising the principle of party autonomy in arbitral proceedings. It also provides an important legal basis for arbitral institutions, including the Middle Commercial Arbitration Center (MCAC), to implement and develop consolidation mechanisms in practice.

2. MCAC Rules on Consolidation of Disputes

Article 15 of the MCAC Arbitration Rules provides as follows:

“1. The parties may agree to consolidate multiple disputes into a single proceeding. The Centre shall decide whether or not to consolidate multiple disputes after taking into account the relevant circumstances.

2. Unless otherwise agreed by the parties, the disputes shall be consolidated into the arbitration in which the proceedings were first commenced.”[1]

Based on the applicable legal framework and the MCAC Arbitration Rules, the consolidation process at MCAC may be summarised as follows:

- The claimant and respondent are involved in multiple disputes administered by MCAC;

- During the course of the proceedings, the parties agree to consolidate such disputes into a single arbitration;

- The Arbitral Tribunal considers and decides whether to grant consolidation after assessing the relevant factors.

In the absence of an agreement to the contrary, where consolidation is ordered, the disputes will be consolidated into the arbitration in which proceedings were first commenced.

In practice, consolidation is typically considered where: a request is made by one or more parties; the disputes involve the same parties; the arbitration agreements are compatible (e.g. in terms of seat, language, and applicable law); and the disputes are closely connected from a legal perspective, such as arising out of the same contract or a series of related transactions.

The application of this mechanism promotes procedural consistency and enhances the efficiency of case management and dispute resolution by the Arbitral Tribunal.

Conclusion

The consolidation of multiple disputes in commercial arbitration constitutes a practical procedural mechanism for enhancing efficiency and ensuring consistency in the resolution of disputes. The concurrent resolution of related disputes within a single proceeding not only optimises resources but also mitigates the risk of conflicting arbitral awards.

In the context of Vietnam’s legal framework increasingly aligning with international practice, the effective use of consolidation requires parties to carefully draft clear and consistent arbitration agreements at the contract formation stage, and to exercise due consideration when proposing consolidation. This, in turn, contributes to improving the overall quality of arbitral dispute resolution, ensuring transparency, efficiency, and consistency with the demands of international integration.
