Key legal question
Whether the cantonal order refusing to enter on the supervision complaint was challengeable by constitutional complaint
Extracted holding
Yes. Because the chamber treated the filing as a formal legal remedy and imposed a procedural fee, the decision had appealable character and the complainant had a protected interest.
Extracted reasoning
Although a pure supervisory complaint is ordinarily not attackable by constitutional complaint, the Thurgau 'Aufsichtsbeschwerde' under § 71 VRPG is a formal extraordinary remedy with party status and an entitlement to a decision.
