Key legal question
Whether the appeal against the cantonal remand decision was admissible under Art. 93 BGG.
Extracted holding
The appellants did not show that immediate review would avoid extensive evidence-taking with significant time or cost; the appeal is therefore inadmissible.
Extracted reasoning
A remand decision is an interim decision. The appellants failed to substantiate, with specific disputed facts and evidence offers, that the conditions of Art. 93(1)(b) BGG were met. The size and complexity of the claim alone are insufficient.
