Advisory Experience

Prof. Slot has written many opinions for national court and arbitration procedures, for the General Court, the Court of Justice of the European Union as well as for major law firms.

He has been involved in a considerable number of high profile arbitration proceedings, in particular with Arnold & Porter LLP Brussels and Washington, White and Case LLP Brussels, London and New York, Mannheimer Swartling, Stockholm, Freshfields Paris, Cologne and Dusseldorf,  Freget Tasso de Panfieu-avocats Paris and Weil, Gotshal & Manges. All assignments involved major arbitral disputes in Central European countries. In the arbitral dispute between AES v. Hungary and Electrabel v. Hungary, he assisted the Hungarian government. The first case was decided in favor of Hungary in September 2010. In addition, in AES case, the European Commission intervened as amicus, involves novel issues regarding the interaction of the Energy Charter Treaty and the EC Treaty's provisions regarding competition. In 2015 he assisted the Bulgarian government in the arbitral dispute between the Bulgarian government and EVN. In 2015 he advised the French electricity company Energie Direct in a state aid case.

In 2009 and 2010 he has advised the Nederlandsche Bank (the Dutch Central Bank) in matters relating to the state aid given to ING in the time of the financial crisis.

Has extensive experience in advising several national energy companies as well as foreign companies (EDF) on matters of European law in particular competition,  state aid and energy law. He was for a number of years legal advisor to Gasunie (the National Gas Corporation of the Netherlands) as well as Statkraft (the national electricity company of Norway). In both positions the compatibility of long term contracts with EC law was a major issue of concern. In 2010 he advised E.ON in a dispute with the European Commission. He also advised the German Network Authority on trans-border electricity connections.
