This article examines for which type of transactions the use of a competing, transparent, non-discriminatory and unconditional tender procedure excludes the provision of an advantage and for which type of transactions this is not the case. In answering that question, it will be discussed whether the found distinction can be logically explained and criteria will be developed in accordance with which transactions can be distinguished for which a tender procedure will exclude State aid and for which it will not. Finally, suggestions will be given on how the framework of assessment could be made more consistent. Keywords: Advantage; Public Procurement; SGEI.
