							                Parallel arbitration refers to the situation where multiple arbitration proceedings are conducted at the same time, often involving the same parties or related disputes. While these arbitrations remain separate, they may deal with overlapping issues, facts, or legal principles. This approach can offer certain advantages, such as faster resolution of issues, but it also introduces challenges like the risk of inconsistent rulings or fragmented decision-making.
Parallel arbitration occurs when two or more arbitration proceedings involving similar or related issues take place at the same time, but they are handled by separate arbitral tribunals. The key characteristics of parallel arbitration include:
Parallel arbitration typically arises when there are several agreements or disputes between the same parties, but the issues are distinct enough to warrant separate arbitrations. For instance, if parties have multiple contracts with arbitration clauses, each contract may give rise to a separate arbitration, even if the disputes are related.
In parallel arbitration, all the arbitrations are pursued at the same time. These proceedings are not consolidated into a single arbitration; rather, each dispute is handled independently, but at the same time. The arbitral tribunals might coordinate their proceedings to avoid inconsistencies in the outcomes.
In many cases, parallel arbitration is used when the disputes involve overlapping facts or legal principles. For example, the same event or set of transactions may give rise to multiple, separate claims.
Parallel arbitration allows for the simultaneous resolution of related disputes, which can be more efficient than sequential proceedings. This is especially useful when the issues involved are time-sensitive or if they arise out of the same commercial context.
While separate proceedings can incur costs for both parties and arbitrators, they can also save costs in terms of legal strategy, as the arbitrators can decide on the issues faster and more concurrently. Furthermore, having multiple arbitrations can reduce delays that may occur if the proceedings are held sequentially.
Each arbitration can be handled by a different arbitral tribunal, which might allow the parties to select arbitrators with expertise in different aspects of the dispute. This gives parties the flexibility to tailor their approach to each individual issue.
Since parallel arbitrations are handled by different tribunals, there is a significant risk that the decisions in the separate arbitrations may contradict each other. This could create confusion and undermine the overall coherence of the legal resolution. The risk is higher when similar issues or facts are involved but are treated differently by different arbitrators.
Managing multiple parallel proceedings requires careful coordination. Different tribunals might handle procedural matters in different ways, and conflicting timelines or approaches could create confusion. This lack of uniformity can complicate the resolution process and delay outcomes.
While parallel arbitration might save time in some cases, in others it can lead to inefficiency, as multiple tribunals may request similar information, hold similar hearings, or go over the same facts. This repetition can increase costs and extend the overall duration of the proceedings.
Parallel arbitration can lead to fragmented decision-making, especially if there are multiple arbitrators interpreting the same facts or legal principles in different ways. This fragmentation might prevent a unified approach to the resolution of the disputes.
The UNCITRAL Model Law on International Commercial Arbitration does not explicitly address parallel arbitration but provides flexibility in how arbitrations are conducted. It allows for multiple proceedings, though consolidation or coordination may depend on the agreement between the parties and the arbitrators.
Under the International Chamber of Commerce (ICC) Arbitration Rules, parallel arbitrations may be permissible if the arbitration clauses in the relevant contracts allow for it. The ICC also provides a mechanism to avoid inconsistent decisions when multiple arbitrations are underway.
The London Court of International Arbitration (LCIA) allows parallel proceedings, but it encourages parties to consider consolidating related disputes if possible. If multiple arbitrations are pending, the LCIA can take steps to facilitate coordination between the tribunals.
Suppose two companies, A and B, have signed two separate contracts, one for the supply of goods and the other for services. Disputes arise under both contracts, and each party files for arbitration under the respective agreements. The disputes are related because they arise from a single business relationship.
Parallel arbitration is a useful tool for resolving multiple disputes involving the same parties, especially when time or cost efficiency is needed. However, it comes with risks, including the potential for conflicting decisions and fragmented resolutions. Parties considering parallel arbitration should weigh the benefits of resolving related issues concurrently against the potential challenges of managing separate but overlapping proceedings.
