(23)The possibility for competent authorities to request corrective measures to remedy or avoid repetition of non-compliance with this Regulation, and the possibility for the ECB to impose effective, proportionate and dissuasive sanctions for infringements of this Regulation are essential elements in implementing the CPMI-IOSCO principles to the fullest extent allowed under the Treaty and the Statute of the ESCB. While corrective measures may only be imposed for infringements of this Regulation, there could be situations that merit initiating the procedure for the imposition of such measures on the grounds of suspected non-compliance, giving a SIPS operator the opportunity to be heard and to provide explanations before an infringement is established. In cases where the SIPS operator is a branch, the corrective measures or sanctions should be imposed on the branch.
