Brussels, 26/06/2002 (Agence Europe) - The Commission has published a communication setting out the way in which rules of competition will apply to pending cases in the coal and steel industries, currently governed by the rules of the Treaty setting up the European Coal and Steel Community, which expires on 23 July (on this, see yesterday's EUROPE page 17). The cases dealt with according to provisions of the ECSC Treaty now come within the rules of the EC Treaty regarding competition, like the rest of the economy, except for the nuclear sector, which remains governed by the Euratom Treaty. The transition process should not cause major problems but the Commission regarded it opportune, so as to provide them with legal security, to guide the companies concerned regarding anti-trust and merger control rules, as well as for Member states in respect of State aid rules. Whence the publication of a Communication "concerning certain aspects of the treatment of competition cases resulting from the expiry of the ECSC Treaty", which summarises the most important changes stemming from the transition to the EC system and explains how the Commission intends to deal with specific issues raised by this transition in the areas of anti-trust, merger control and State aid control.
