Questione giuridica chiave
Whether the constitutional complaint against the cantonal supervisory decision was admissible.
Decisione estratta
The complaint was admissible insofar as it challenged the constitutionality of Art. 30 GebV SchKG under Art. 9 BV; the request to annul the office's fee assessment directly was inadmissible.
Motivazione estratta
A constitutional complaint is available for alleged violations of constitutional rights not otherwise reviewable under the debt-enforcement appeal route, and it may only be directed against the final cantonal decision.
