Whether the appeal against the refusal to order a second expert report was admissible under Art. 319 let. b ch. 2 CPC because the decision could cause irreparable harm.
The wife showed no concrete difficult-to-repair harm; the appeal was therefore not admissible.
The challenged refusal was an instructional order. For such orders, appeal lies only if the law allows it or if they can cause irreparable harm. A mere refusal to order a second expert report does not, without specific substantiation, meet that threshold.
