Questão jurídica principal
Whether the Obergericht violated the cantonal constitution by refusing an appeal against the evidentiary order
Decisão extraída
No violation was shown, because the Obergericht decided only on the appealability of an interlocutory evidentiary ruling, not on the appealability of the main judgment.
Fundamentação extraída
The constitutional provision guaranteeing review in civil cases concerns the main dispute; a negative ruling on a preliminary evidentiary question does not determine the appealability of the final merits judgment.
