Key legal question
Whether the refusal to order production of medical literature cited by the expert was immediately appealable to the Federal Tribunal.
Extracted holding
The decision was an incidental procedural ruling and was not immediately appealable because no irreparable legal harm was shown.
Extracted reasoning
Procedural and evidentiary decisions are normally not capable of causing irreparable legal prejudice. The appellant could renew her request later and raise any violation of hearing or defense rights in an appeal against a final judgment; the alleged delay was only factual harm.
