Oscillating Trailers and the Warranty Law in the Context of Sales Law
The decision of the Higher Regional Court of Zweibrücken on July 23, 2024 (Case No.: 4 U 63/24), which deals with the issue of the defectiveness of an oscillating trailer, raises central questions in the tension field between the concept of defects in sales law and general product quality. Especially for commercial buyers, manufacturers, or dealers of commercial vehicles and machines, as well as institutional investors, the dogmatic and practical classification of defects is of far-reaching importance.
Concept of Defects in Sales Law: Fundamental Criteria and Standards
Conformity with Contract and Buyer’s Expectations
According to §§ 434 ff. BGB, the question of defects is primarily determined by the agreed quality, alternatively by the suitability for ordinary use and the quality customary for items of the same type. Public-law requirements, such as road traffic approval requirements, also regularly form a standard for justified buyer expectations.
Against this background, not every deviation from ideal behavior should be classified as a material defect. Rather, the specific execution of the vehicle must be evaluated concerning contractual assurances, product-related informational duties, and relevant standards.
Differentiation: Usability versus Product-Specific Behavior
A particular significance is attached to the difference between the basic usability of an item and its product-specific behavior. With technical products, a phenomenon that occurs within the inherent design possibilities – such as a certain oscillation of a trailer during specific driving maneuvers – may not constitute a defect, provided the vehicle’s integral functionality is not impaired and there is no violation of safety requirements.
The Judgment: Evaluation of the Oscillating Trailer Symptom
Standard of Examination: Deviation from Norm or Type-specific Behavior?
In the case decided, a buyer sought to rescind the contract for a new trailer. The main argument he presented was that the trailer oscillated during driving – especially at higher speeds with an empty load area. The Higher Regional Court of Zweibrücken clarified that this behavior would only be equated with a material defect if it exceeded the usual degree for vehicles of this type and objectively diminished utility or road safety.
In this context, the court thoroughly evaluated the technical design, the adaptation to the transported weight, and the fact that comparable models from competitors reacted similarly under similar conditions. It was deemed decisive that there was no design-induced malfunction, but rather behavior inherent in this construction.
Implications for Contractual Design and Risk Allocation
The decision highlights that, especially with mass-produced technical products, an entirely individual freedom from defects is not owed, but merely a usability corresponding to the agreed and usual standard. If specific requirements or purposes of use are to become part of the contract, a clear and documented agreement is required between the contracting parties.
Repercussions on Sales Law Disputes
Standard of Perception and Expectations in Business Dealings
The judgment underscores the importance of the objective perception as a guideline for assessing technical peculiarities. In determining whether a material defect exists within the meaning of § 434 BGB, it is not the buyer’s subjective disappointment over product-typical characteristics but the deviation from justified, objectively comprehensible user expectations that is decisive.
Moreover, obtaining expert evaluations can be relevant, especially for assessing whether functionality in the context of industry-specific interpretations has been significantly compromised.
Consequences for Warranty, Rescission, and Damages
Following the line of the Higher Regional Court of Zweibrücken, claims for rescission or reduction are regularly excluded in cases of product-inherent properties without functional impairment – unless there is a contractual agreement on quality that clearly covers the complained behavior. For companies and merchants, the case law clarifies the central role of contract design and accompanying product documentation.
Conclusion and Note on the Importance of Competent Contract Design
The decision of the Higher Regional Court of Zweibrücken emphasizes that the assessment of defectiveness in the commercial and capital goods sector requires careful consideration of technical product standards, contractual agreements, and market expectations. For actors who regularly engage with complex sales or work contracts in the technical sector, it is advisable to clearly regulate potential risks and peculiarities in advance.
