Key legal question
Whether the appeal against the interlocutory judgment was admissible under Art. 93 LTF
Extracted holding
The appeal was not admissible because the alleged harm was not irreparable in the legal sense.
Extracted reasoning
Any possible prejudice from the interlocutory decision could be fully remedied by a later appeal against the final judgment, including complaints about the Liechtenstein judgments and costs; only temporary procedural disadvantages were alleged.
