Kernrechtsfrage
Whether the appellant had a legal interest under Art. 61 URG to bring a negative declaratory action against ProLitteris.
Extrahierter Entscheid
The legal interest was lacking because the continued uncertainty about the alleged payment obligation was not shown to be intolerable for the appellant.
Extrahierte Begründung
A declaratory action under Art. 61 URG requires that the uncertainty about the legal relationship be removed by judgment and that continued uncertainty be unreasonable; the cantonal court could apply this criterion consistently with federal case law.
