Article 1
1. The Member States shall take the measures necessary to ensure that decisions taken by contracting entities may be reviewed effectively and, in particular, as rapidly as possible in accordance with the conditions set out in the following Articles and, in particular, Article 2 (8), on the grounds that such decisions have infringed Community law in the field or procurement or national rules implementing that law as regards: (a) contract award procedures falling within the scope of Council Directive 90/531/EEC; and (b) compliance with Article 3 (2) (a) of that Directive in the case of the contracting entities to which that provision applies. 2. Member States shall ensure that there is no discrimination between undertakings likely to make a claim for injury in the context of a procedure for the award of a contract as a result of the distinction made by this Directive between national rules implementing Community law and other national rules. 3. The Member States shall ensure that the review procedures are available, under detailed rules which the Member States may establish, at least to any person having or having had an interest in obtaining a particular contract and who has been or risks being harmed by an alleged infringement. In particular, the Member States may require that the person seeking the review must have previously notified the contracting entity of the alleged infringement and of his intention to seek review.
