1.At the request of the requesting authority, the requested authority shall, subject to Articles 16 and 17:
(a)recover an administrative penalty and/or fine that has been imposed in accordance with the laws and procedures of the requesting Member State by a competent authority or confirmed by an administrative or judicial body or, where applicable, by industrial tribunals, which is not subject to further appeal; or
(b)notify a decision imposing such a penalty and/or fine.
In addition, the requested authority shall notify any other relevant document related to the recovery of such a penalty and/or fine, including the judgment or final decision, which may be in the form of a certified copy, that constitutes the legal basis and title for the execution of the request for recovery.
2.The requesting authority shall ensure that the request for recovery of an administrative penalty and/or fine or the notification of a decision imposing such a penalty and/or fine is made in accordance with the laws, regulations and administrative practices in force in that Member State.
Such a request shall only be made when the requesting authority is unable to recover or to notify in accordance with its laws, regulations and administrative practices.
The requesting authority shall not make a request for recovery of an administrative penalty and/or fine or notification of a decision imposing such a penalty and/or fine if and as long as the penalty and/or fine, as well as the underlying claim and/or the instrument permitting its enforcement in the requesting Member State, are contested or challenged in that Member State.
3.The competent authority requested to recover an administrative penalty and/or fine or to notify a decision imposing such a penalty and/or fine which has been transmitted in accordance with this Chapter and Article 21, shall recognise it without any further formality being required and shall forthwith take all the necessary measures for its execution, unless that requested authority decides to invoke one of the grounds for refusal provided for in Article 17.
4.For the purpose of recovery of an administrative penalty and/or fine or notification of a decision imposing such a penalty and/or fine, the requested authority shall act in accordance with the national laws, regulations and administrative practices in force in the requested Member State applying to the same or, in the absence of the same, a similar infringement or decision.
The notification of a decision imposing an administrative penalty and/or fine by the requested authority and the request for recovery shall, in accordance with the national laws, regulations and administrative practices of the requested Member State, be deemed to have the same effect as if it had been made by the requesting Member State.
