Upon the Transposition of European Directive No. (UE) 2020/1828 of 25/11/2020, whose new rules will apply from 25/6/2023, each EU Member State will be required to have at least one collective action, responding to the limit Its minimum requirements, aimed at protecting the collective interests of consumers, The directive called it the representative action, can be bringing against any professional who breaches his obligations, by organizations he calls qualified entities, provided they are designated in advance by member states. And that representative action can be domestic, as it can be cross-border. However, the main weakness of the directive is that it sets unified and binding criteria for all Member States to designate qualified entities for the purpose of bringing cross-border representative actions, and In contrast leaves those countries free to set criteria for designating qualified entities for the the purpose of bringing national representative action, in a way that leads to a lack of coordination between Member States, and to increase the risk of forum shopping. Therefore, This study is content to shed light on this particular problem, and on the solutions that some propose to address it. [ABSTRACT FROM AUTHOR]
