Questione giuridica chiave
Whether the CHF 4,400 file-access fee for a non-party third person had a sufficient formal legal basis
Decisione estratta
No. The cantonal tariff could not extend the circle of fee payers beyond what the formal law allowed, and the amount was not a mere clerical fee.
Motivazione estratta
The charge was a causal fee requiring a formal legal basis. The delegation to adopt a 'tariff' did not authorize the cantonal legislature to impose the fee on persons or under conditions not covered by the procedural statutes. Cost-covering and equivalence principles could not cure the absence of a formal statutory basis for the taxable event and liable persons.
