Ellex Valiunas Arbitration Team Introduces the First Translated Book
Since domestic arbitration is becoming more complex, Ellex Valiunas has taken an important step to spread international doctrine of arbitration in Lithuania. Jurgita Petkute-Guriene, Vilija Vaitkute Pavan, Giedre Aukstuoliene, and Rapolas Kasparavicius have translated into Lithuanian the “Legal Theory of International Arbitration” authored by Emmanuel Gaillard, one of the prominent arbitration professionals in the world.
The book was presented during Vilnius Arbitration Day 2016 on 7 October 2016. Its first copies were donated to the Lithuanian universities, Supreme Court of Lithuania, Court of Appeal of Lithuania and Vilnius District Court. The book will not be distributed for commercial purposes.
This is the first translation by Ellex Valiunas of a book published by internationally recognized legal scholars. Ellex Valiunas will continue on this path and other translations are expected in the near future.   
The e-book for personal use only, can be found here.
