A record 966 new cases were filed with the ICC International Court of Arbitration in 2016. This unprecedented 20% growth is explained by continuing expansion in all continents, especially North and Central America and Africa, and in all sectors of industry. These figures also factor an influx of small claims in a Californian collective action. The widening use of ICC arbitration demonstrates the versatility of the ICC Arbitration Rules, which leave the parties free to adapt aspects of the procedure to their particular needs while ensuring that cases are conducted efficiently and in accordance with best practices.
