Recently the European Commission has launched a new online database on unfair commercial practices. The aim of this new e-service is to improve understanding of the Unfair Commercial Practices Directive by making publicly available data on what is seen as such a practice. This database can be useful both for consumers and national enforcement agencies. What may be found on the website? It contains many various sources helping to determine what is an unfair commercial practice: national legislations, jurisprudence, administrative decisions, reference to relevant literature.
