Questão jurídica principal
Whether the public-law appeal could challenge the cantonal court's refusal to investigate the 1999 settlement and the resulting standing issue under Art. 29(2) Constitution and Art. 131(2) LP.
Decisão extraída
The complaint was inadmissible in public-law proceedings because the argument concerned the application of federal law and should be reviewed in a reform appeal.
Fundamentação extraída
The right to be heard extends only to relevant facts; relevance depended on federal law. Since the challenge targeted the cantonal court's application of Art. 131(2) LP and possibly Art. 20 CO, it fell within the reform appeal and was barred by the subsidiary nature of the public-law appeal.
