Litigation and Dispute Resolution, TMT, IP and Energy


István Réczicza is a partner in Dentons’ global Litigation and Dispute Resolution group and he is also the Hungary Managing Partner.

He focuses on the areas of telecommunications, energy, mergers and acquisitions (M&A), and intellectual property regulation, particularly as these relate to transactions involving foreign investment. In the course of representing clients in these fields, István has become one of Hungary's leading figures in the analysis of industry regulation and the drafting of proposed amendments in connection with such legislation.

István has a significant track record advising on litigation and domestic and international arbitration matters, as well as white collar matters. Over the years he has represented numerous clients before the International Centre for Settlement of Investment Disputes (ICSID), including recently the Republic of Hungary in a significant victory following an arbitration tribunal’s rejection of all claims brought by the plaintiff. He also represented a client in the first ever case brought before the Hungarian Energy Arbitration Court. Furthermore István has significant white collar experience, having conducted several internal corporate investigations.

Widely recognized as a leading M&A lawyer, István has advised on a number of landmark transactions. For example, he advised a UK leading airport operator in the US$2.2 billion privatization of a Central European airport operator, in relation to the acquisition of the said airport operator by a Spanish construction group, and a newly formed entity in its sale of the airport operator's majority stake in the above mentioned Central European airport operator to a leading German construction company for €1.9 billion. István also advised the airport operator on the restructuring of approximately €1.6 billion of its debt.

One of Hungary’s leading figures in the field of TMT regulation, István has advised the government and state agencies on issues including the revision of national communications and media legislation, and has also helped to prepare Hungary’s implementation of EU directives on electronic communications.
