Markus BurgstallerHogan Lovells US LLP

According to one client, Hogan Lovells International LLP is ‘one of the leading firms in the sector with a sophisticated grasp of the overlapping legal regimes‘. The practice regularly advises on complex issues of public and private international law, including identifying the legitimate government of a state after civil war; the relationship and interaction between international public law, European Union law and international organisations; human rights law and international economic law. It fields a team of ‘dedicated lawyers‘, who are also experienced in investment treaty arbitration, particularly in the energy and telecoms sectors. Markus Burgstaller continues to be involved in cutting-edge issues at the intersection of international investment law and EU law; he successfully represented the Slovak Republic in its highly publicised dispute with Achmea in which the Court of Justice of the European Union ruled arbitration clauses in intra-EU investment treaties are incompatible with EU law. Charles Brasted, who is the co-head of the global government relations and policy advocacy practice, advises on high-profile, politically sensitive issues with a governmental element. Julianne Hughes-Jennett specialises in international human rights litigation involving corporations.
