9. If the legal system of a Member State does not provide for administrative fines, this Article may be applied in such a way that the competent supervisory authority requests the imposition of a fine, and it is imposed by a competent national court, provided that the effectiveness of those legal remedies and the equivalence of their effect to an administrative fine imposed by a supervisory authority are ensured. The fines imposed must in any event be effective, proportionate, and dissuasive. Within the time limit set out in Article
91(2), such Member States shall notify the Commission of the provisions of their law which they have adopted in accordance with this paragraph by 25 May 2018, and thereafter without delay of any subsequent acts amending or changes affecting those provisions.
