The ICC published its Dispute Resolution statistics for 2018 on 11 June 2019. The statistics confirm that the number of women appointed and confirmed has increased and nearly doubled, from 136 in 2015 to 273 in 2018, which corresponds to 18.4% of the arbitrators appointed in 2018. This is an increase also from 2017 (249 women appointed). Parties nominated as many women arbitrators as appointed by the ICC Court, 115 and 113 respectively.
The number of women acting as president or sole arbitrator has also increased. In 2018, 32% of women appointed or confirmed as arbitrators acted as president (31% in 2017) and 30% as sole arbitrators (26% in 2017).
