(46)In several cases where the ECB is consulted under this Regulation, its opinion should be binding insofar as it obliges a competent authority to refuse, withdraw or limit an authorisation of the issuer of asset-referenced tokens or to impose specific measures on the issuer of asset-referenced tokens. Article 263, first paragraph, TFEU provides that the Court of Justice of the European Union (the ‘Court of Justice’) should review the legality of acts of the ECB other than recommendations or opinions. It should be recalled, however, that it is for the Court of Justice to interpret that provision in light of the substance and effects of an opinion of the ECB.
