Suspension of revision proceedings pending CJEU preliminary ruling on EU law interpretation

The BGH 1st Civil Senate suspended the revision proceedings pursuant to § 148 (1) ZPO until the Court of Justice of the European Union renders a decision in the pending preliminary reference procedure C-440/23, meaning no party prevailed at this stage and the prior lower court decision remains in force pending the EU court's ruling. The dispute concerns a civil litigation matter where the domestic court determined that a uniform interpretation of relevant EU law is necessary before proceeding with the final judgment on the merits. The decisive legal basis is the obligation of national courts to request a preliminary ruling from the CJEU under the principle of cooperative jurisdiction, triggering the statutory stay of proceedings under German civil procedure law.
