The article attempts to examine the structures of the EFTA Court in order to gain insights into its effectiveness. For this purpose the article relies on a rational system approach developed within social sciences to improve understanding the performance of public organisations and calibrated to examine international courts by the ERC Project Researching Conditions for Effective International Adjudication. Under the conceptual and analytical framework advanced by the Effectiveness Project the article, therefore, examines the main structures of the EFTA Court: for example, the Court's budget, jurisdictional rules, judicial independence and main legal doctrines. The article will also, in relation to some aspects, attempt to conduct a qualitative assessment of how some of these features relate to the effectiveness of the Court.
