This is an exceptional procedure applied restrictively to the special cases and circumstances provided for in Article 32(2) to (6) (Book I) and Article 269(a) to (j) (Book II):

It should be stressed that in order to use this procedure (and the procedure set out in Article 26(2)(b) of Law 4412/2016) for contracts with an estimate value above the value limits, the prior assent of the HSPPA is required, in accordance with Article 2(2)(c)(dd) of Law 4013/2011, except in the case of force majeure.

Useful material:

• Guideline (K.O.) 1 of the HSPPA: 'Procedure for the issuance of a decision by the Hellenic Single Public Procurement Authority on requests by contracting authorities/entities on the provision of assent on the use of the negotiated procedure of Article 2(2)(c)(dd) of Law 4013/2011’ (Online Publication No ΒΙ6ΜΟΞΤΒ-ΔΚΦ)](https://diavgeia.gov.gr/doc/ΒΙ6ΜΟΞΤΒ-ΔΚΦ?inline=true), which, however, must be updated with the latest changes to the legislative framework on public procurement.

• use of the National Electronic Public Procurement System (NEPPS – Articles 22(1), 26 and 258(1));
