In order to effectively ensure correct and efficient implementation, Member States shall make sure that at least the tasks set out in this Article are performed by one or more authorities, bodies or structures. They shall indicate to the Commission all authorities or structures competent for those tasks.

2. Member States shall ensure that the application of public procurement rules is monitored.

Where monitoring authorities or structures identify by their own initiative or upon the receipt of information specific violations or systemic problems, they shall be empowered to indicate those problems to national auditing authorities, courts or tribunals or other appropriate authorities or structures, such as the ombudsman, national parliaments or committees thereof.
