Legal Developments by:
Dittmar & Indrenius


    In February Parliament adopted new rules in relation to both domestic and international jurisdiction in civil matters. The new jurisdiction rules will enter into force on 1 September 2009. As Finland is a member state of the European Union, the EU rules on international jurisdiction, such as the Brussels I and II Regulations, (EC) No 44/2001 and (EC) No 2201/2003, and other provisions regarding certain specific subject matters, are applicable. The new rules on international jurisdiction will apply in cases falling outside the territorial or subject matter scope of the applicable EU regulations or international conventions binding Finland.
