The field of public procurement with regard to works, services and supply contracts, is dominated by the regulation of EU directives and the relevant EU case-law, along with the provisions of the national law and the case law that has emerged from the national courts and the Greek Council of State.

Our firm follows closely the developments in the field of public procurement, in which it holds a tradition with counselling activity on issues of public contracts.

We advise our clients on all of the stages of implementation of a public contract. From the selection of the appropriate procedure at the preliminary stage, to the amicable resolution of any issues at the execution stage and, finally, to the revision/modification or termination of a contract. In addition to the out-of-court and legal representation of contracting authorities as well as contractors (e.g. before the Authority for the Examination of Preliminary Appeals), we undertake, through substantiated expert legal opinions, the resolution of complex legal issues, which often arise in the ever-evolving field of public procurement.

Our firm has extensive experience in defending public procurement cases before the Court of Justice, where it has successfully represented the Hellenic Republic (Cases C-399/05, C-250/07) and also in submitting or dealing with complaints before the European Commission.
