Questão jurídica principal
Whether the appeal against the procedural order refusing a second expert report was admissible under Art. 319 CPC.
Decisão extraída
The order was only appealable if it could cause irreparable harm, which the appellant did not show.
Fundamentação extraída
The challenged ruling was an instruction-order type decision, not a final or incidental decision ending the case. No difficult-to-repair prejudice was alleged, and under former Vaud procedure the judge freely evaluates expert evidence, so refusal of a second expertise did not create such harm.
