The mandate of the European Court of Auditors (ECA) and Supreme Audit Institutions (SAIs) of the European Union Member States – with regard to auditing of the management and utilisation of EU funds – overlap to some extent.

In his article, the author presents the main areas of cooperation between the ECA and SAIs: participation of SAIs in the Court’s audit visits in the Member States, the activities aimed to mitigate the risk of duplicated audits, and cooperative audits.
