Challenges in Public Procurement Contract Execution
For the functioning of a public procurement system the performance of the public procurement contract represents
a critical part. The extent to which contracting authorities are allowed to amend a procurement contract after signature is one of
the greyest areas in European public procurement. For the first time a EU Directive on public procurement regulates explicitly
the contract performance. This paper aims at to present the challenges that might appear during the execution phase of a public
procurement contract. Also, the present paper will provide an assessment of the rulings of the Court in this matter.
