The Arbitration Act 1996 - Summary of Substantive Legal Amendments (Effective 1/8/2025)

Area of Reform

Provision

Summary of Amendment

A. New Sections and Concepts

Applicable Law

New s.6A

Introduces a default rule: if no express choice of law governs the arbitration agreement, the law of the seat applies. A contract-wide governing law clause does not suffice. Reflected in s.2(2)(za) and s.83.

Duty of Disclosure

New s.23A

Requires arbitrators and proposed arbitrators to disclose any relevant circumstances that might reasonably give rise to doubts as to their impartiality. A mandatory provision (Schedule 1).

Summary Disposal

New s.39A

Allows tribunals to issue summary awards where a party has no real prospect of success, provided both parties have a fair opportunity to be heard.

Emergency Arbitrators

New s.41A

Enables emergency arbitrators, where appointed under agreed rules, to issue peremptory orders enforceable under s.42. “Emergency arbitrator” and “peremptory order” added to s.82(1) and s.83.

B. Amendments to Key Existing Provisions

Court Removal of Arbitrator

s.24(5A)

Court may only order arbitrator to pay costs if bad faith is shown. See cross-reference in s.29(1).

Arbitrator Resignation

s.25

Replaces fee liability regime. Court may now decide on entitlement to or return of fees/expenses on application by any relevant party (new s.25(3)).

Arbitrator Immunity

s.29(4–5)

Clarifies that an arbitrator is only liable upon resignation if doing so was unreasonable in all the circumstances, subject to agreements or court orders.

Jurisdictional Challenges

s.32

Removes the “good reason” requirement (s.32(2)(b)) and other hurdles (s.32(3)). New s.32(1A) inserted. Tightens court access after tribunal rulings on jurisdiction.

Enforcement of Orders

s.42

Expanded to include peremptory orders made by emergency arbitrators, not just the full tribunal.

Court Support Powers

s.44

Amended to: (1) include non-parties (s.44(1)); (2) require permission from tribunal/emergency arbitrator in non-urgent cases (new s.44(4)); (3) add procedural and appeal provisions (s.44(6A–7)).

Preliminary Points of Law

s.45

Mirrors changes to s.32: removes need to prove lack of delay or agreement. New test for leave refers to either condition in s.45(2).

Costs Awards

s.61

Tribunal powers no longer conditional on party agreement (s.61(1)). Can award costs even if tribunal lacked jurisdiction (new s.61(1A)). “Costs follow the event” is now a default rule, subject to party agreement (s.61(3)).

Challenges to Award

s.67

Reworded for clarity (s.67(1)(b)). Courts may declare awards ineffective (new s.67(3)). New subsections (3B–3D) limit new grounds at court stage unless applicant shows prior unawareness despite diligence.

Time Limits

s.70(3A–3B, 9)

Introduces a flexible “applicable date” rule for calculating time limits for applications/appeals, including corrections and additional awards. New s.70(9) inserted.

C. Repeals and Omissions

Domestic Arbitration Provisions

ss.85–88

Repeals provisions distinguishing domestic arbitration, aligning fully with international standards.

Consequential Repeals

Schedules 3 & 4

Removes outdated references (e.g. to court appeal routes) consistent with the above reforms.

Key Takeaways

These reforms mark the most substantial update to the Arbitration Act in nearly 30 years. Stakeholders should review:

  • The expanded duties and default powers of arbitrators,
  • The recalibrated court support framework, and
  • The streamlined mechanisms for challenging jurisdiction and awards.
