Abstract

This article examines the phenomenon of collective or aggregate civil litigation, manifested in different forms as a class action, representative action, or group action. Different countries have adopted different models of collective civil litigation. This diversity presents a challenge in drawing comparisons, and raises the need to study the different techniques involved. This article summarizes the adoption of a technical perspective. Following this, the article reviews the availability and limitations of the research techniques in relation to what we want. It discusses the questions of goals of collective procedures, levels of need, technical modes of operation, and evaluation. The ultimate goal is to be able to compare different techniques and decide which ones might work best and in what circumstances or types of situation. There is plenty of research to be done in this field.
