The principal procurement procedures under Public Procurement Law No 4734 are the open procedure and the restricted procedure. Negotiated procedures may be used where the special conditions set out in the Law arise. In recent years, however, the proportion of negotiated procedures, and within them the proportion of unadvertised negotiated procedures under Article 21(b), has risen sharply.
