Kernrechtsfrage
Whether the request to take additional evidence was admissible in the federal complaint.
Extrahierter Entscheid
The request for additional evidence was inadmissible because new evidence and new requests are barred where they could have been raised below.
Extrahierte Begründung
The complaint must identify the federal-law violations concisely; parties may not introduce new requests, facts, objections, or evidence if they had the opportunity to do so in the cantonal proceedings.
