국제상사중재판정의 준거법선택에 있어서 당사자자치의 원칙 - 당사자에 의한 lex mercatoria의 선택과 준거법 분할지정의 가능여부를 중심으로 -

Currently, it is the general trend that the party's autonomy principle is applicable in determining the applicable law for the international private law and the international commercial arbitration. The purpose of this article is to make research on the party's autonomy principle for the international commercial arbitral awards. For this purpose ist to analyse regal issue the applicability of the lex mercatoria and the possibility of $d\acute{e}pe\c{c}age$ relating to the party autonomy. In this Article ist dealt with Art. 29 para. 1 of the Korean Arbitration Act in comparison with Art. 28 para. 1 UNCITRAL Model Law and Art. 1051 para. 1 of the German Code of Civil Procedure. The Art. 28 para. 1 UNCITRAL Model Law and Art. 1051 para. 1 of the German Code of Civil Procedure provides equally. "The arbitral tribunal shall decide the dispute in accordence with such 'rules of law' as chosen by the parties as applicable to the substance of the dispute. Any designation of the law or legal system of a given State shall be construed, unless otherwise expressed, as directly referring to the substantive law of that State and not to its conflict of laws rules." The term 'rule of law' used to describe the applicability of the lex mercatoria and the possibility $d\acute{e}pe\c{c}age$. Unlike Art. 28 para. 1 UNCITRAL Model Law and Art. 1051 para.1 of the German Code of Civil Procedure. Act, Art. 29(1) of the Korean Arbitration Act provides that the arbitral tribunal shall decide the dispute in accordence with the 'law' chosen by the parties as applicable to the substance of the dispute. However the majority view in Korea takes the position that the term 'law' should be interpreted broadly so as to encompass 'rules of law' at UNCITRAL Model Law and the German Code of Civil Procedure.
