Questione giuridica chiave
Whether the subsidiary constitutional complaint was admissible despite the dispute concerning only costs and expenses.
Decisione estratta
The remedy was admissible only as a subsidiary constitutional complaint because the value in dispute did not reach the statutory threshold and no exception applied.
Motivazione estratta
Where only costs and expenses are contested, the value in dispute is determined by those amounts alone; here it remained below CHF 30,000.
