Enforcement of wage claim: Calculation of statutory interest and allocation of litigation costs

The Federal Labor Court partially reversed and remanded the decision of the Bavarian State Labor Court, ultimately upholding the lower instance's partial award and ordering the plaintiff/counter-defendant to pay the defendant/counter-claimant 3,283.06 euros plus statutory interest, while dismissing the remainder of the claim and assigning all litigation costs to the plaintiff. The dispute concerned a wage claim and related counter-claims, likely arising from an employment relationship where the plaintiff sought compensation or benefits that were challenged by the defendant. The decisive legal basis involved the interpretation of contractual wage entitlements and the procedural rules governing the assessment of final costs and interest in labor disputes, as applied by the BAG in correcting the appellate court's partial findings.
