»The Landlord's Lien de lege lata et ferenda. A Critical Revision of the Statutory Security Model«: The paper deals with the hitherto unsettled architecture of today's landlord-tenant lien law and the question whether the statutory provisions should be passed into legal history altogether or whether individual variations of a remeasurement and redesign should be retained. The author analyzes §§ 562 ff. BGB in detail from a legal-historical, -theoretical and -dogmatic perspective and also tries to take the economic dimension into account.
