Article 39
The Advisory Committee shall be required to give its opinion, in a purely advisory capacity, on: (a) all proposed contracts for supplies or services, including studies, for which the estimated value equals or exceeds the thresholds in the Council Directives on public procurement procedures; (b) any proposed agreement supplementary to any contract as referred to in point (a) whenever there are significant changes, particularly when the effect of such supplementary agreement would be to alter the amount involved in the original contract; (c) any proposed supplementary agreement the effect of which would be to raise the total amount involved in a contract already concluded above the thresholds referred to in point (a); (d) questions arising at the time of conclusion or in the course of performance of contracts (e.g. cancellation of orders, requests for remission of penalties for delay, departures from the specifications and general conditions of contract), should the matter be sufficiently serious to justify a request for an opinion; (e) at the request of one of the Member States referred to in Article 25 or of Iceland or Norway, or of a member of the Advisory Committee, or of the Deputy Secretary-General, proposed contracts involving an amount below the thresholds referred to in point (a), where they consider that such contracts involve questions of principle or are of a special nature.
