In our local law, there are two Acts that contain provisionsconcerning written notifications to be made in the course of arbitralproceedings. Although the previous Civil Procedure Act No. 1086 didnot contain explicit provisions in this regard, the jurisprudenceconsistently referred to the Notifications Act. As to the new CivilProcedure Act No. 6100, its article 438/I explicitly cross-references theNotifications Act. These provisions, however, are only relevant todomestic arbitration. The cited provision of the Civil Procedure Act isunclear and needs interpretation and clarification as to the extent andscope of the cross-reference and the kinds of actions undertaken in thearbitral proceedings which it covers. As far as international arbitration isconcerned, the International Arbitration Act No. 4684 contains specialprovisions, and does not cross-reference any other Act. Notificationissues are closely related to the procedural principle of the right to beheard. To whom, where, how and when a notification is sent are issuesthat are highly important, particularly with respect to the legalimplications of the notification. Therefore, in this study, we discuss theapplication in arbitral proceedings of the notification provisions in ourNotifications Act and the Arbitration Legislation.
