Against a background of increasingly intense legal harmonisation and with the prospects of Central European accession to the EU drawing ever closer, a recent decision of the Hungarian Constitutional Court, Dec.30/1998 (VI.25) AB1 has highlighted the constitutional implications of applying EC law in the domestic system of an associate state. The judgment itself concerned the constitutionality of the competition provisions of the EC-Hungary Europe Agreement (“EA”) together with Decision 2/96 of the Association Council on the relevant Implementing Rules (“IR”). While the Hungarian court is not the first of its type in an associate state to deal with the effect internally of an Association Agreement,2 nevertheless its decision offers certain insights into the judicial response to the integration process in Central Europe.
