This dissertation provides an analysis of the scope and procedure of obtaining documents from the opponent in international commercial arbitration. The goal of this research is to provide an in-depth study of the myriad of detailed questions regarding the procedure and scope of obtaining document production which goes beyond analyzing the differences between common law and civil law practices and takes an international commercial arbitration perspective. The primary aim, however, is not to supply definite answers, but rather to present possible best practices by, for example, discussing various approaches and problematic areas of the topic and also providing the reader with awareness of different aspects that should be taken into account when dealing with document production. To reach this aim, the method of legal dogmatics is predominantly employed. The core of this research is in the interpretation and systematization of international arbitration sources, especially soft law, which provide detailed guidance regarding document production, against the background of legal principles of arbitral procedure. The challenge of conducting research regarding document production is that procedural timetables, document requests, objections and procedural orders are confidential. However, the author of this dissertation had the rare opportunity to research files of ICC cases and anonymized examples from the chosen cases serve as valuable source regarding international arbitration practice. The research is divided into five substantive chapters. In Chapter 2, the framework for document production is discussed. In Chapter 3, the procedure and requirements of the request for documents is analyzed. Here im-portant questions are considered, such as what is the basis of a party’s right to obtain documents, how to delimit a narrow category of documents, what is meant by relevance and materiality, can a party request documents relating to issues it does not have the burden of proving and also when are the documents considered as being in a party’s control. In Chapter 4, the attention turns to the possible bases for an objection to a document request, such as privilege, confidentiality, data protection, unreasonable burden of production etc. Chapter 5 contains analysis of the questions connected to the actual production, including the tribunal’s order to produce or dismiss a production request, the form of production and the consequences of non-compliance, i.e. adverse inferences and financial consequences. In Chapter 6, the issue of national courts’ assistance in obtaining documents from the opponent is addressed. The detailed results of the analysis are presented throughout this dissertation and the significance of this research is in the discussion of the specific questions. Nonetheless, on the basis of the conducted study certain key find-ings are also drawn. First, the research shows that many issues can be resolved on the basis of balancing principles of international commercial arbitration. Consequently, there is no need for more regulation. Arbitration needs to remain flexible. Predictability should not be achieved on the level of arbitration rules and soft law, but in specific arbitration proceedings. Second, there are important legal implications relating to production of electronic documents and participants of the arbitral process need to be aware of them. Third, arbitrators are very cautious when making decisions as to not violate possible due process or public policy requirements. In fact, only one arbitral award has been set aside due to a reason connected to a document production question. Finally, with respect to many questions regarding the scope and procedure of document production, one can refer to an international commercial arbitration approach.
