Kernrechtsfrage
Whether the appeal against the cantonal decision refusing a credibility expert opinion was admissible despite being an interim decision.
Extrahierter Entscheid
The appeal was inadmissible because the challenged decision was an interim evidentiary ruling and the appellant failed to show irreparable legal harm.
Extrahierte Begründung
Under Art. 93(1)(a) BGG, an appeal against non-final decisions is possible only if irreparable legal detriment is shown. The appellant bears the burden of demonstrating this prerequisite, and no such showing was made.
