EU law does not prevent Member States from providing for an appeal suspending execution of a decision extending the effects of a European arrest warrant.

EU law does, however, require that, in the case where the Member States choose to provide for such an appeal, the decision to extend should be taken within the time-limits provided for by EU law in cases concerning the European arrest warrant. 

It is worth  stressing that in this case  the Conseil constitutionnel, the French Surpeme Court,  decided, for the first time in its existence, to refer a question to the Court of Justice for a preliminary ruling.
