Abstract
The subject of this paper is to describe the current development of the principle of transparency in international dispute settlement and to raise arguments both for and against transparency. In the first part the author deals with the general trend of transparency in arbitration and quasi-judicial dispute settlements in international economic law (ICSID, NAFTA).
And then it addresses two specific areas in which transparency either already happens to be there or it is coming. The first regards the ongoing preparation and discussion of the proposed transparency rules applicable in investment disputes under UNCITRAL Rules.
This area is dedicated to the second part of the article. The third part of the paper focuses on transparency of dispute settlement in the WTO.
