Opinia na temat wniosku dotyczącego decyzji Rady w sprawie zawarcia w imieniu Unii Europejskiej Konwencji Narodów Zjednoczonych dotyczącej przejrzystości w umownych postępowaniach arbitrażowych między inwestorem a państwem [COM(2015) 20 final]

The opinion concerns spreading the use and extending the substantive and temporal scope of the UNCITRAL Rules on Transparency in Treatybased Investor-State Arbitration. Possible conflict of obligations of Member States under international law may arise regardless of whether the United Nations Convention on the transparency will be concluded only by the Europe‑ an Union or by its Member States. The position of the European Commission according to which the Convention relates only to exclusive competence of the European Union should be considered as doubtful.
