(64)The ECB should provide natural and legal persons with the possibility to request a review of decisions taken under the powers conferred on it by this Regulation and addressed to them, or which are of direct and individual concern to them. The scope of the review should pertain to the procedural and substantive conformity with this regulation of such decisions while respecting the margin of discretion left to the ECB to decide on the opportunity to take tho se decisions . For that purpose, and for reasons of procedural economy, the ECB should establish an administrative board of review to carry out such internal review. To compose the board, the Governing Council of the ECB should appoint individuals of a high repute. In making its decision, the Governing Council should, to the extent possible, ensure an appropriate geographical and gender balance across the Member States. The procedure laid down for the review should provide for the Supervisory Board to reconsider its former draft decision as appropriate.
