Legal analysis of systemic investment protection regulation in the European Union's financial sector

After the Treaty of Lisbon the European Union has an exclusive and uniform competence regarding investment agreements within its common commercial policy. Yet the political events in 2016 showed that there are still many regional differences politically and economically, especially after the so-called Brexit and negotiations with the United States of America in relation to transatlantic trade and investment. Therefore, the aim of the research is to determine the legal framework and related problems for unified investment protection within the European Union. Using descriptive, logical and deductive methodology the paper establishes a juristic base consensus for trade and investment policies, concludes that so far those policies have been systemically neglected due to regional differences in economic development and accordingly suggests to unify and protect the common investment policies by using already existing regional judicial mechanisms of member states within a unified code of conduct.
