Questão jurídica principal
Whether the federal appeal against the cantonal inadmissibility decision was admissible under Art. 93 LTF
Decisão extraída
The attack was inadmissible because the refusal of a second credibility expert opinion caused no irreparable legal harm.
Fundamentação extraída
Interlocutory decisions on evidence are normally reviewable only with a final judgment. No exception applied because the requested expertise could still be sought later at trial or on appeal.
