As Macao expects more of judicial efficiency, arbitration is highly valued because of its prominent advantages. Compared with the fast development of its counterpart in Hong Kong, Macao’s arbitration system is still in a rather ‘confused’ stage. This paper seeks to establish a general orientation for the amendment of the arbitration system in Macao by analyzing in detail how the Macao arbitration Law and the Code of Civil Procedure can be applied for optimized efficiency; looking at common misunderstandings of the Constitution, arbitration justice, as well as the limitation of local languages; discussing secret issues and the support of judges around the advantages of arbitration. Ultimately this paper will, by drawing on the experiences of amendment in the United Kingdom and Hong Kong, make rational proposals regarding the amendment of Macao’s arbitration system in view of local realities.
