Key legal question
Whether the federal appeal against the cantonal interim decision was admissible under Art. 93 BGG
Extracted holding
The appellant did not sufficiently show irreparable harm or that immediate admission would avoid extensive evidence proceedings.
Extracted reasoning
Self-standing review of interim decisions is exceptional and must be strictly construed; the appellant bears the burden of substantiating admissibility requirements unless they are obvious. Here, the assertions about saving time and costs were abstract and unparticularized.
