Questão jurídica principal
Whether the cantonal court violated the right to be heard by refusing an expert opinion on the vehicle's maximum authorized weight
Decisão extraída
No. The type-approval documents were decisive; a later manufacturer's attestation could not override them, so further evidence was unnecessary.
Fundamentação extraída
Vehicle technical characteristics are determined through the strict type-approval procedure under the applicable road vehicle rules. The later attestation was not part of that procedure and could not prevail over the official type-approval sheet, making an expertise incapable of changing the outcome.
