On 11 November 2021, the European Court of Auditors (ECA), the European Investment Bank (EIB), and the European Commission signed a new tripartite agreement. It replaces an agreement from 2016 that was concluded between these three institutions. The revised tripartite agreement allows the ECA wider access to EIB documents and data relating to activities carried out under the mandate of the European Commission. The agreement further clarifies the timeline for receiving necessary audit documentation (and in what format), confidentiality, data protection rules, evidence collection methods, and access to information.
