The author's aim is to provide an orientation in the basic norms of European law. The author deals with the act prohibiting discrimination in rewarding and she describes an example of the discrimination which is important not only because the European court of justice applied its test of objective justification for the first time here, but also because in this case European court of justice for the first time involved benefits of employment (e.g. company pension) under the concept of reward. The author also introduces the basic legal norms of the European law concerning the issue of the equal opportunities for men and women. The European law is part of the Czech legal system and it is superior to Czech law, thus the author further points out the possibilities of citizens (like individual) to sue of justice at both national and European courts of justice. She brings out suggestions how to work with the resources of European law and also explanes the role of the European as well as Czech courts of justice in application of the European legal norms generally and particularly in case of the discrimination in rewarding and in treatment.
