Like the Works and the Supplies Directives, the Services Directive provides that contract procedures may be one of three types: the open procedure and the restricted procedure, which contracting authorities are free to choose, and the negotiated procedure, which can only be used in exceptional circumstances.44 Important In open and restricted procedures contracting authorities may request further information from tenderers in order to facilitate assessment of their offers, but it is forbidden to negotiate the terms of such offers.
