On 8 October 2008, the Court of First Instance (CFI) upheld the European Commission's (Commission) decision, and dismissed appeals brought by Le Carbone-Lorraine (LCL), Schunk Kohlenstoff-Technik (Schunk) and SGL Carbon (SGL) regarding their involvement in the electrical and mechanical carbon and graphite cartel. The Commission's decision of December 2003 imposed fines totalling €101.44m on six companies. The plaintiffs’ appeals concerned the Commission’s methodology in calculating the fines. SGL questioned the decision to group the companies into size categories: small, medium and large. However, the CFI confirmed that taking into account the relative size of company turnover is not inconsistent with the principles of equal treatment and proportionality. LCS and Schunk contested the impact of the cartel on large consumers (for example car manufacturers) in view of their significant buying power. However, the CFI upheld the Commission’s right to consider the impact on the market of the cartel as a whole to determine the gravity of the infringement. LCL attempted to claim a reduction in its fine for providing information to the Commission concerning the destruction of documents by another participant in the cartel, Morgan Crucible. The CFI rejected the claim on the basis that the information had not contributed to identification of the infringement and bringing it to an end. Moreover, Morgan Crucible itself had provided sufficient information to the Commission to disclose the breach and was entitled to immunity.
