Key legal question
Whether the subsidary constitutional complaint was admissible against the cantonal ruling on definitive debt enforcement and the refusal to extend the deadline.
Extracted holding
The constitutional complaint was admissible because the statutory value threshold for an ordinary civil appeal was not met and no question of principle was invoked; the incident refusal could also be reviewed together with the final decision.
Extracted reasoning
The Federal Supreme Court found the formal conditions satisfied and held that the final decision and the incident ruling were both reviewable in the same constitutional complaint under the Federal Supreme Court Act.
