Key legal question
Whether the appeal against the cantonal remand order was admissible under Art. 93 LTF
Extracted holding
The remand order did not expose the appellants to a sufficiently long and costly evidentiary procedure, so immediate federal appeal was not available.
Extracted reasoning
No irreparable prejudice was shown. The alleged further evidence did not demonstrate an unusually extensive or expensive taking of evidence; the need for possible additional witnesses or inquiries was insufficient.
