Questão jurídica principal
Whether the refusal of anticipatory evidence under Art. 158 ZPO was arbitrary
Decisão extraída
Yes. If a medical expert report is likely indispensable in the later damages action, denying a protected interest in obtaining it in advance is contradictory and arbitrary.
Fundamentação extraída
Anticipatory evidence serves to clarify litigation and evidentiary prospects for a concrete substantive claim. The existing private medical reports did not replace a court expert report, and the claimant had made the necessary prima facie showing that the report would be central in any later action.
