Article 1
The increased reduction in social security contributions in respect of manual workers granted under the Maribel bis/ter scheme to employers who carry on their principal activity in one of the sectors most exposed to international competition constitutes illegal State aid because it was not notified to the Commission in advance in accordance with Article 93 (3) of the EC Treaty. It is furthermore incompatible with the common market within the meaning of Article 92 (1) of the EC Treaty and cannot qualify for any of the derogations laid down in Article 92 (2) and (3).
