The new ICC Rules of Arbitration, in force on 1 January 2021, set forth a new stage of the institution’s evolution towards a more “efficient” and “transparent” dispute resolution at the international level. It is worth noting the amendments incorporated into the new Rules relating to (i) the so-called “complex arbitration”, (ii) the enhanced formal flexibility in order to support the conduct of ICC arbitration exclusively by electronic means, (iii) the preservation of the validity of the arbitral award through the adoption of, among other measures, the possibility of rendering an “additional award”, (iv) the arbitrators’ independence in respect of “third party funders” and parties’ representatives, and, lastly, (v) ICC investment arbitration.
