Within the time limit stipulated in the previous article, the offender must pay the amount of the fixed fine, unless, within the same time limit, he submits a request for exemption to the service indicated in the notice of offence. In the cases provided for by article 529-10, this request must be accompanied by one of the documents required by this article. This request is forwarded to the public prosecutor.
Failing payment or a request submitted within forty-five days, the fixed fine is automatically increased and recovered in favour of the Treasury by virtue of a writ of execution issued by the Public Prosecutor’s Office.
