Questão jurídica principal
Whether the appeal against the cantonal remand order was admissible under Art. 93 LTF
Decisão extraída
The remand order did not expose the appellants to a sufficiently long and costly evidentiary procedure, so immediate federal appeal was not available.
Fundamentação extraída
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.
