ON ESTABLISHING APPLICABLE LEGISLATION IN THE CASE OF THE SIMULTANEOUS EXECUTION OF WORK IN MORE THAN ONE MEMBER STATE IN THE COORDINATION OF SOCIAL SECURITY SYSTEMS

Abstract

The subject of the study is determining legislation applicable in case of pursuing activity as an employed person simultaneously in the territory of more than one Member State under the coordination of social security systems in the EU. This issue in question is of interest of case law, especially one of the Supreme Court and the one of the Court of Justice of the European Union. It is of fundamental practical importance. Since conditions for determining the applicable legislation are different, more liberal in the case of simultaneous work in the territory of at least two Member States than in the case of the posting of workers, a conclusion that in the case of performing work under the same employment contract with one employer in successive periods of time, it possible to determine that legislation according to the rule applicable in the case of simultaneous pursuing activity in the territory of more than one Member State, means that employers gain an opportunity to apply social security legislation in force at their seat without any time limits. This, in turn, directly affects legal conditions under which freedom to provide services and freedom of movement of workers related thereto may be exercised.
