Case / decision no:

2025/2841 / 2026/135

Decision date:

Court:

Danıştay

Case number:

2025/2841

An important judgment of the Council of State has been published concerning the updating of work experience certificates submitted in construction tenders. In the case in question the contracting authority took the view that, notwithstanding the application of an interim unit price system, the index for December of the preceding year had to be taken as the basis for updating the work experience certificate; it therefore treated the certificate as insufficient and excluded the tenderer's bid from the evaluation.
