English Arbitration Act: Law Commission's progressive amendments

By Ioannis Alexopoulos and Pietro Grassi
The Law Commission proposes vital changes to the English Arbitration Act of 1996, bolstering London's stance in international arbitration
The Law Commission recently published its final report on the English Arbitration Act of 1996 (the Arbitration Act), accompanied by a draft bill. The final report proposes several amendments to the Arbitration Act. This is a welcomed initiative to support London’s position as the main hub for international commercial arbitration considering significant competition from other jurisdictions, such as Singapore.
On 1 December 2020, for instance, amendments to the Singapore International Arbitration Act came into force with the aim to strengthen Singapore’s legislative framework for international arbitrations. In the same vein, major arbitral institutions have also recognised the need to modernise their arbitration rules in recent years, such as the LCIA (2020), ICC (2021), ICSID (2022), and SCC (2023).
Here are some of the key revisions which the Law Commission has proposed:
Codification of an arbitrator’s duty of disclosure.
The Law Commission proposes to make it clear that arbitrators have an ongoing duty to disclose any circumstances that might reasonably give rise to a justifiable doubt as to their impartiality. The proposed legislative provision, however, does not prescribe what needs to be disclosed. The Law Commission has simply recommended that the duty of disclosure should be based on what the arbitrator ought reasonably to know as opposed to their actual knowledge. This continuing duty of disclosure was clarified by the UK Supreme Court in Halliburton v Chubb (2018), where it was held that arbitrators have a duty to disclose any circumstances which might reasonably give rise to justifiable doubts as to their impartiality.
The proposed codification of the duty of disclosure strikes a balance between transparency and accepting that the international arbitration community remains a close-knit (albeit international) community. An arbitrator’s connection to one of the parties is often inevitable (especially in certain industries and areas of expertise) and, therefore, what is regarded as important is the openness and transparency about such connections, to enable users to assess the effect of such connections on impartiality. The Law Commission has also clarified that failure to make a disclosure can give rise to justifiable doubts as to an arbitrator’s impartiality and leave them open to removal under section 24 of the Arbitration Act.
Introduction of a power of summary disposal
Among the Law Commission’s proposed reforms, there is a call for an express summary disposal based on the threshold applied by English courts, ie, where the claim has ‘no real prospect of success’ and where there is ‘no other compelling reason’ for it to continue to a full hearing. As such, summary disposal allows arbitrators to dispose of any issue or claim that lacks merit. This seems to be similar to the “manifestly without merit” test set forth in Article 22(viii) of the LCIA Rules."
