The Constitutional Court;

-Annulled the regulation in Article 166 of the Code of Civil Procedure, which governs cases filed in civil courts of the same level and capacity within the same judicial district that are consolidated due to a connection between them, on the grounds that it left no room for the judge of the first court to which the cases were consolidated to reject the file.
