Collective redress procedures, in which a number of claimants with similar or related interests group together to bring a combined action against a defendant or group of defendants, are becoming increasingly important in civil litigation. The availability and effect of collective redress differs widely between jurisdictions. Some countries have embraced the concept and permit collective actions in a variety of claims. In others, the procedure may only be used in limited circumstances and for specified causes of action. Businesses, particularly those with cross-border operations, need to be aware of the potential differences in approach across their global market – and the consequent risks they may face.
