They are therefore free to choose their own legal form and organization. However, it must be clearly pointed out that any national central bank will perform such additional tasks within its own responsibility and for its own account and that such tasks are not deemed to be part of ESCB activities.
Furthermore, the ECB Governing Council may decide by a two-thirds majority that certain activities fail to comply with the contractual and statutory tasks and duties of the ESCB and may decree their discontinuation. Previous work by the EMI on this issue, particularly studies on legal convergence, indicate that restrictions will be imposed only if such an activity threatens to impair the single monetary policy.
