For the last three decades, legal scholarship on the judicial review of legislation has dominated comparative constitutional studies. Moreover, one of the emerging interests in comparative constitutional law is pre-enactment (ex ante) control of constitutionality. [---] This article investigates whether similar pre-enactment constitutional review mechanisms exist elsewhere. For this purpose, it will examine East Nordic constitutional practice and ask whether there is a particular type of pre-enactment constitutional review in Finland and Sweden. The function to review constitutionality of proposed legislation belongs to non-judicial mechanisms in both Finland and Sweden. [---]
