Answer ... The Polish courts have domestic jurisdiction in cases governed by Polish law if the seat of arbitration is in Poland. The Polish courts also have domestic jurisdiction if Polish law provides for court action related to arbitration whose seat is outside Poland or has not been determined.
Answer ... The parties are solely authorised to decide on the seat of arbitration, which, under Polish law, determines the jurisdiction of the Polish courts. No specific provision is applicable when the substantive law is unclear; in such case, the rules on lack of choice of seat of arbitration apply (see question 12).
