(150) In order to strengthen and harmonize administrative sanctions for violations of this Regulation, each supervisory authority should be authorized to impose administrative monetary penalties. This Regulation should list the types of violations and indicate the upper limit and criteria for determining the related administrative monetary penalties, which the competent supervisory authority should determine on a case-by-case basis taking into account all the relevant circumstances of the situation, with due regard in particular to the nature, gravity, duration and consequences of the violation, as well as the measures taken to comply with the obligations under this Regulation and to prevent or minimize the consequences of the violation. If the administrative monetary penalty is imposed on an undertaking, "undertaking" is to be understood for these purposes in accordance with Articles 101 and 102 TFEU. If the administrative monetary penalty is imposed on a person who is not an enterprise, the supervisory authority, in determining the appropriate amount of the monetary penalty, should take into account the general level of income in the Member State concerned and the economic situation of that person. To promote the consistent application of administrative fines, a consistency mechanism can also be used. Member states should determine whether and to what extent administrative monetary penalties should be imposed on public bodies. The imposition of an administrative monetary penalty or the issuance of a warning does not affect the application of other powers of supervisory authorities or other sanctions under this Regulation.
