On March 2, 2007, five companies, including Emerson Electric and Robert Bosch, issued a claim for damages, exemplary damages and restitution in the UK Competition Appeal Tribunal against four manufacturers of graphite carbon products which the EU Commission held in December 2003 had operated an illegal price fixing cartel. The claimants argue first that as purchasers of the cartel companies' products they suffered from the artificially inflated prices and secondly that the cartel participants were unjustly enriched. With the exception of the whistleblower, who received immunity from the fines, all the members of the cartel have appealed the Commission's decision to the Court of First Instance and there is some doubt about whether the claims can continue as against those companies until the litigation is concluded. The claim is the second to be brought in the UK as a result of a Commission decision.
