Requests for additional documentation and clarification
Article 27
After the ECB has opened applications or tenders, it may request candidates or tenderers to submit, supplement, clarify or complete information or documentation which is or appears to be missing, incomplete or erroneous within an appropriate time limit. Such requests shall be made in full compliance with the principles of equal treatment and transparency; in particular, they shall not lead to any preferential treatment, give a competitive advantage, or change the terms of an application or tender.
