Yes.
The Director of the ITM may forward a request for notification or enforcement of an administrative penalty or fine imposed on a service provider in the event of non-compliance with the relevant provisions regarding the posting of workers and pronounced in the Grand Duchy of Luxembourg to the competent authorities of another Member State in which the natural person against whom the decision was pronounced habitually resides or in which the legal person against whom the decision was pronounced has its registered office.
In such case, the decision which has been forwarded to another Member State will no longer be enforceable in the Grand Duchy of Luxembourg.
The decision may however again be enforced in the Grand Duchy of Luxembourg where the State in which enforcement was initially requested gives notice to the Director of the ITM of non-enforcement of the decision by virtue of its national law.
