A. LEGISLATION, TRENDS AND TENDENCIES There have been no significant changes to Polish arbitration legislation in the past year. B. CASES There have been no significant court decisions in Poland in relation to arbitration in the last year. C. REGULATION OF COUNSEL CONDUCT IN INTERNATIONAL ARBITRATION C.1 New IBA Guidelines on Party Representations The Guidelines do not play a significant role in Polish arbitration. On the one hand, parties and tribunals are free to adopt or address the Guidelines, but on the other hand this rarely happens. The Guidelines are treated rather as subsidiary rules concerning matters that are insufficiently described in the CPC (e.g., challenging an arbitrator).
