Suspension of revision proceedings pending CJEU preliminary ruling on compatibility of domestic suspension rules with EU law

§ 148 Abs. 1 ZPO; Suspension of revision proceedings pending CJEU preliminary ruling on compatibility of domestic suspension rules with EU law: 1 ZPO, pending a preliminary ruling by the Court of Justice of the European Union on a reference filed in a separate but related case. The dispute concerned a civil matter within the jurisdiction of the First Civil Senate, where the appellate court had reached a decision on a substantive legal issue that now requires clarification from the CJEU. The decisive legal basis for the operative outcome is the procedural rule allowing for the stay of national proceedings in anticipation of a binding interpretation of European Union law, specifically triggered by the pending preliminary reference identified in the sister case. No party prevailed on the merits at this stage; the proceedings are administratively halted to ensure consistency with EU jurisprudence.
