The European Court of First Instance (CFI) has upheld the fines imposed by the European Commission in 2002 on three out of four plasterboard producers for cartel activities. The CFI reduced the fine of the fourth producer, BPB, from EUR 138.6 million to 118.8 million by granting an additional 10 per cent reduction on top of the 30 per cent already granted to take account of the extent of cooperation provided by BPB during the investigation. The total fine imposed on all cartel participants was therefore reduced from EUR 478.32 million to EUR 458.52 million. The cartel related to a secret information exchange system set up to monitor market trends and avoid over-aggressive competition on the plasterboard market between 1992 and 1998.
