CMS has once again been recognised as one of the world’s leading international arbitration practices following its inclusion by Global Arbitration Review (GAR) in its 2026 edition of the prestigious GAR 30 rankings.
This recognition reflects CMS’s deep bench of experienced arbitration practitioners and its longstanding commitment to delivering high-quality arbitration services to clients worldwide.
The GAR 30 is an annual ranking of the world's leading arbitration practices, published by GAR, a specialist journal and news service. Widely regarded as a leading benchmark in the field, it employs a data-driven methodology to assess hundreds of firms globally based on the size, complexity, and significance of their caseloads, as well as activities that reflect their international reputation.
In this 19th edition of the rankings, CMS is placed 13th globally, reinforcing its standing as one of the world's leading arbitration practices. CMS has also been recognised by the GAR 30 as one of the busiest arbitration practices globally, attesting to the continued confidence of its clients.
With capabilities spanning across diverse sectors, governing laws, as well as in investment treaty matters, CMS's truly international practice is especially well placed to support clients across the full spectrum of international arbitration.
