»Model Case Procedures by Consumer Associations in Conjunction with European and German Principles of Procedural Law«: Consumers tend to refrain from seeking legal redress where companies violate the law through unfair practices. These practices often harm a large number of consumers. The high costs of bringing legal action and other uncertainties deter consumers from enforcing their rights. The German legislator introduced a model case procedure that allows consumers to seek collective redress. This paper examines the question of whether mass damage events can be handled effectively and in a procedurally economical manner through model case procedures.
