Kernrechtsfrage
Whether the book price-maintenance system is a competition agreement under cartel law
Extrahierter Entscheid
Yes. The scheme qualifies as a competition agreement because it comprises enforceable vertical agreements and coordinated conduct.
Extrahierte Begründung
Art. 4(1) KG covers agreements and coordinated conduct between undertakings on different market levels; the formal vertical structure does not exclude cartel-law qualification.
