»Deceit and Misleading Commercial Practices. The Relationship between Individual and Collective Enforcement for Misleading Advertising towards Consumers«: Misleading commercial practices can be combated under unfair competition law, but how can consumers defend themselves against unfair practices? This thesis presents a dogmatic analysis of the relationship between unfair competition law and civil law remedies and examines whether individual remedies under the German Civil Code and the collective legal protection under the Unfair Competition Act are independent regimes or interconnected mechanisms, especially in view of § 9 para. 2 UWG.
