Key legal question
Whether the federal complaint was admissible given the amount in dispute and the absence of constitutional claims.
Extracted holding
The complaint was inadmissible because the amount in dispute was below CHF 30,000 and no violation of constitutional rights was invoked.
Extracted reasoning
A public-law appeal is excluded under Art. 85(1)(a) BGG for this amount; without constitutional complaints, subsidiary constitutional appeal is also unavailable.
