Questão jurídica principal
Whether the filing was admissible as a subsidiary constitutional complaint and what could be reviewed
Decisão extraída
Only the challenged cantonal appellate decision was reviewable; the value in dispute did not reach the threshold for an ordinary civil appeal, so only subsidiary constitutional complaint was available.
Fundamentação extraída
The relevant amount was the CHF 639.25 claim in dispute before the cantonal court. Under the subsidiary constitutional complaint, only violations of constitutional rights may be raised, subject to strict substantiation.
