In this edition, the PI publishes thematically comprehensive, more detailed versions of the responses to clients’ requests, covering more countries. The Papers provide an overview of the different legislative options regulating certain areas of social life in different countries. They thus generate an invaluable knowledge base for choosing the appropriate arrangement for the Czech system. The key tools applied in the Papers are the comparative method, which enables a detailed and thorough understanding of the differences in legal arrangements, the sources of such differences and the consequences they lead to, and the analysis of a particular topic. The Papers are mainly used to describe the legislation of selected countries. The comparison focuses primarily on the Member States of the European Union.
