Whether the appeal against the proof order concerning the allocation of expert-fee advances was admissible under Art. 103 and 319 CPC.
The appeal was inadmissible because Art. 103 CPC allows review only of the amount of the advance, not of the allocation ratio, and the amount had not yet been set.
The challenged decision concerned only the sharing of the anticipated expert costs. Since no concrete advance amount had been determined, the appeal was premature.
