Questão jurídica principal
Whether the appeal against the cantonal order on costs and party compensation after a remand was admissible under Art. 93 BGG.
Decisão extraída
The challenged decision was an interim decision; no irreparable legal disadvantage was shown, so the Federal Supreme Court could not hear the appeal immediately.
Fundamentação extraída
A remand does not end the proceedings, and the cost/compensation ruling remains accessory to the main issue. Any disadvantage could be reviewed later together with the final decision, while delay or extra expense alone is insufficient under Art. 93 Abs. 1 BGG.
