On 16 December 2008, the European Court of Justice (ECJ) ruled on whether EU procurement legislation exhaustively establishes the grounds for excluding a bidder from participating in a tender for a public contract. The case in question (C-213/07) came before the ECJ on a preliminary reference from a Greek court. Under Greek law, contractors with interests in the media sector are excluded from the award of public works contracts. An issue arose in relation to an invitation for tender for the construction of infrastructure of a new high-speed railway line. The Director of one of the bidding companies had a son who was a member of the board of directors of two Greek media undertakings. The Greek court hearing the dispute sought clarification from the ECJ as to whether the Greek law on exclusion is compatible with EU law. The ECJ considered the grounds under the EU procurement directive (2004/18/EC) for excluding contractors. It ruled that the Directive exhaustively lists the grounds for excluding a contractor from participation in the contract based on professional quality (e.g. solvency, economic and financial capacity) but found that national governments are entitled to provide further grounds for exclusion for reasons of transparency and equal treatment, provided that these are proportionable. In this instance, the ECJ took the view that the law in question was disproportionate because it did not provide any opportunity for contractors to demonstrate that any link they may have with the media sector did not raise any real risks in relation to the relevant contract.
