# Art. 31 — Exercise of supervisory powers and imposition of sanctions

MAR Article 31 — Exercise of supervisory powers and imposition of sanctions. Regulation (EU) No 596/2014, Chapter 5 — Administrative measures and sanctions.

1. Member States shall ensure that when determining the type and level of administrative sanctions, competent authorities take into account all relevant circumstances in order to apply proportionate sanctions, including, where appropriate:
   1. the gravity and duration of the infringement;
   2. the degree of responsibility of the person responsible for the infringement;
   3. the financial strength of the person responsible for the infringement, as indicated, for example, by the total turnover of a legal person or the annual personal income of a natural person;
   4. the importance of the profits gained or losses avoided by the person responsible for the infringement, insofar as they can be determined;
   5. the level of cooperation of the person responsible for the infringement with the competent authority, without prejudice to the need to ensure disgorgement of profits gained or losses avoided by that person;
   6. previous infringements by the person responsible for the infringement;
   7. measures taken by the person responsible for the infringement to prevent its repetition; and
   8. the disadvantage for the person responsible for the infringement resulting from the duplication of criminal and administrative proceedings and penalties for the same conduct.
2. In the exercise of their powers to impose administrative sanctions and other administrative measures under [Article 30](/mar/chapter-5-administrative-measures-and-sanctions-art.-30-34/30.md), competent authorities shall cooperate closely to ensure that the exercise of their supervisory and investigative powers, and the administrative sanctions that they impose, and the other administrative measures that they take, are effective and appropriate under this Regulation. They shall coordinate their actions in accordance with [Article 25](/mar/chapter-4-esma-and-competent-authorities-art.-22-29/25.md) in order to avoid duplication and overlaps when exercising their supervisory and investigative powers and when imposing administrative sanctions in respect of cross-border cases.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://www.mica.wtf/mar/chapter-5-administrative-measures-and-sanctions-art.-30-34/31.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
