Dr. Victor Tsilonis is a principal legal counsel and CEO at Newlaw law firm, Vice-President for Victims & Chairman of the Professional Standards Advisory Committee of the International Criminal Court Bar Association (2019-2020), Alternate Member of the International Criminal Court Disciplinary Board  (2018-2022), visiting lecturer at the Law School of the Democritus University of Thrace for the postgraduate course of International Criminal Justice (2018-2019) and international law expert included in the OSCE Consultancy Roster and the Roster of Experts of the International Nuremberg Principles Academy with over 20 publications and 15 conferences’ participation. These include ‘The Jurisdiction of the International Criminal Court’ (Springer, 2020), a book which covers holistically not only the issues surrounding the Court's jursidiction but also the ICC core crimes, i.e. war crimes, crimes against humanity, genocide and the crime of aggression.

He is authorised to appear before the International Criminal Court, the European Court of Human Rights and the Supreme Court of Greece. Moreover, he is a member of the National Criminal Law Experts’ Association with significant experience in litigation as well. Victor previously was the coordinator of the Thessaloniki’s Bar Expert Group on commenting and evaluating the judicial decisions, while in 2010 and 2011, he lectured on English Legal Terminology and Translation at the Thessaloniki Bar (Greece).

Following the completion of his LL.M. in Criminal Justice at the University of Nottingham in 2003 (while working contemporaneously part-time at the Alumni Relations during his full-time LL.M), Victor interned at the International Criminal Tribunal for the Former Yugoslavia (ICTY) in 2004 where he worked on the Milosevic case. Along with his legal practice, he embarked upon a PhD on international criminal law (the Jurisdiction of International Criminal Court: the prerequisites of its jurisdiction), which he successfully defended on Tuesday 10 May 2016.

In April 2016 Victor Tsilonis was included in the List of Counsel able to appear before the International Criminal Court. He therefore joined a select group of lawyers who are deemed fully capable of representing victims or defend accused persons before the International Criminal Court and rendered NEWLAW the first Greek legal firm that is capable of handling international criminal law cases.

After the enactment of  Law No. 3869 of 2010 (aka Katseli's Law), which enabled private insolvency in Greece, Victor was member of the EKPOIZO consumers’ protection legal team for two years and became one of the leading experts in this field as well. As a result of this expertise, he has advised thousands of Greeks who struggle financially and has assisted approximately one hundred families to retain their indebted primary residences despite having unpaid debts and being in arrears.

Victor is also a regular columnist, writer and translator. He is the editor-in-chief of Intellectum, a multidisciplinary journal, (www.intellectum.org). Intellectum is the only Greek journal to be a fully-fledged member of the Eurozine network (www.eurozine.com). which comprises some of the most prominent non-academic European journals on thought and culture. In his role as editor-in-chief, Victor has interviewed many prominent individuals, such as Ulrich Beck, Carla Del Ponte, David S. Oderberg, Sue Black, Paul Johnston, Richard Katula, William Schabas et al.
