The range of the subjects for study and research available to law students at universities and law schools has been extended over the recent years. To large extent, those newly introduced disciplines and areas of learning cover a relatively limited scope of subjects which are related to the major, “foundation” courses. However, a development of the professional orientation in the study of law and legal research, as well as a shift towards a new framework of professional law education also require diversification of specific subjects. Therefore, the purpose of this article is to outline the International Tax Law course and its potential as a separate discipline for study and research.
