In matters of jurisdiction, any court other than the enforcement judge must declare of its own motion that it does not have jurisdiction.
The enforcement judge may neither modify the terms of the court decision on which the proceedings are based, nor suspend its enforcement. However, after service of the summons or seizure deed or from the date of the hearing provided for in article R. 3252-17 of the Labour Code, as the case may be, he has the power to grant a period of grace.
The enforcement judge may declare of his own motion that he does not have jurisdiction.
