“34. The principal objective of the Community rules in that field is the opening-up of public procurement to undistorted competition in all the Member States (see, to that effect, Case C’26/03 Stadt Halle and RPL Lochau [2005] ECR I’1, paragraph 44). 35. In order to attain that objective, it is important that the contracting authorities do not release information relating to contract award procedures which could be used to distort competition, whether in an ongoing procurement procedure or in subsequent procedures. 36. Furthermore, both by their nature and according to the scheme of Community legislation in that field, contract award procedures are founded on a relationship of trust between the contracting authorities and participating economic operators. Those operators must be able to communicate any relevant information to the contracting authorities in the procurement process, without fear that the authorities will communicate to third parties items of information whose disclosure could be damaging to them. 37. Accordingly, Article 15(2) of Directive 93/36 provides that the contracting authorities are obliged to respect fully the confidential nature of any information furnished by the suppliers”
“39. Admittedly, those provisions relate to the conduct of the contracting authorities. It must nevertheless be acknowledged that their effectiveness would be severely undermined if, in an appeal against a decision taken by a contracting authority in relation to a contract award procedure, all of the information concerning that award procedure had to be made unreservedly available to the appellant, or even to others such as the interveners. 40. In such circumstances, the mere lodging of an appeal would give access to information which could be used to distort competition or to prejudice the legitimate interests of economic operators who participated in the contract award procedure concerned. Such an opportunity could even encourage economic operators to bring an appeal solely for the purpose of gaining access to their competitors’ business secrets”
“It follows that, in a review procedure in relation to the award of public contracts, the body responsible for that review procedure must be able to decide that the information in the file relating to such an award should not be communicated to the parties or their lawyers, if that is necessary in order to ensure the protection of fair competition or of the legitimate interests of the economic operators that is required by Community law”
“The adversarial principle means, as a rule, that the parties have a right to a process of inspecting and commenting on the evidence and observations submitted to the court. However, in some cases it may be necessary for certain information to be withheld from the parties in order to preserve the fundamental rights of a third party or to safeguard an important public interest (see Rowe and Davis v The United Kingdom [GC] no 28901/95, ?61, ECHR 2000’II and V v Finland no 40412/98, ?75, ECHR 2007’…)”
“50. Finally, the maintenance of fair competition in the context of contract award procedures is an important public interest, the protection of which is acknowledged in the case-law cited in paragraph 47 of this judgment. 51. It follows that, in the context of a review of a decision taken by a contracting authority in relation to a contract award procedure, the adversarial principle does not mean that the parties are entitled to unlimited and absolute access to all of the information relating to the award procedure concerned which has been filed with the body responsible for the review. On the contrary, that right of access must be balanced against the right of other economic operators to the protection of their confidential information and their business secrets. 52. The principle of the protection of confidential information and of business secrets must be observed in such a way as to reconcile it with the requirements of effective legal protection and the rights of defence of the parties to the dispute (see, by analogy,Case C-438/04 Mobistar [2006] ECR I’6675, paragraph 40) and, in the case of judicial review or a review by another body which is a court or tribunal within the meaning of Article 234 EC, in such a way as to ensure that the proceedings as a whole accord with the right to a fair trial”
“53. To that end, the body responsible for the review must necessarily be able to have at its disposal the information required in order to decide in full knowledge of the facts, including confidential information and business secrets”
“’The so-called rules of natural justice are not engraved in tablets of stone. To use the phrase which better expresses the underlying concept, what the requirements of fairness demand when any body, domestic, administrative or judicial, has to make a decision which will affect the rights of individuals depends on the character of the decision-making body, the kind of decision it has to make and the statutory or other framework in which it operates.’ Accordingly, what fairness demands varies according to the context”
“Mr Griffiths submits that it is a basic imperative of the need of fairness that a party who will be affected by a public decision is entitled to know the case against him. He relies (specifically in the context of Ground of Appeal 2, to which I shall come shortly) on such well known authority as Ex p Fayed[1998] 1 WLR 763 and Hadmor Productions v Hamilton[1983] 1 AC 191 , 233. Now, the signal feature of the present appeal is that it concerns rival applications for a licence to undertake a commercial venture. In such an instance there is, I think, a distinction to be drawn for the purposes of Mr Griffiths’ submission between a right to know the details of the rival’s case, and a right to know the decision-maker’s concerns about one’s own case. The decision-making body, the Authority, is concerned to arrive at a result in the public interest in conformity with the obligations laid on it by the 1994 Act. In the execution of that process no applicant is shown the details of any other applicant’s bid. In that sense they are treated equally; all the competitors are in the same boat. It would be obviously unfair if one applicant saw his opponent’s bid, but the opponent did not see his. But if every applicant (there may sometimes, no doubt, by more than two) saw every other’s bid, and was entitled to comment and challenge and criticise, the resulting prolongation and complexity of the decision-making process can scarcely be exaggerated”
“There is no question of sacrificing fairness to administrative convenience. The duty of fairness always takes its place in a practical setting. Where the setting involves statutory functions imposed in the public interest, the court must be alert to see that they are fulfilled and not frustrated. Here, as I have said, all competitors are in the same boat. In my judgment, in a competition case like this (in addition to the elementary imperative of impartiality in the decision-maker) fairness imposes two broad requirements: (1) that an applicant be told the substance of the decision-maker’s concerns about his own case, and (2) that each applicant be treated like every other: there should, to use the hackneyed phrase, be a level playing-field. The first of these requirements applies the distinction I drew earlier: the applicant is entitled to be told of the decision-maker’s concerns about his own case, but not the details of his rival’s case”
