Key facts of the case:
The referring tribunal considered a provision of Belgian law it was bound to apply to be in contradiction with the rule of law (or with fundamental rights not specified). It was, however, barred from disapplying that provision (or to refer this question, i.e. of compatibility of the said provision with Union [then: Community] law, to ECJ) by its obligation to refer first to the national constitutional court or, in this case, to refrain from referring, because the constitutional court had already accepted the provision as not infringing national fundamental rights. So the tribunal asked ECJ to assess the compatibility of this said obligation with Union law, namely Article 6 TEU (pre-Lisbon version) and Article 234 TEC, read in conjunction with Article 6 ECHR.
Results (sanctions) and key consequences of the case:
The Court of Justice of the European Union clearly has no jurisdiction to reply to the question referred by the tribunal de première instance de Liège (Belgium).
