Key legal question
Whether the complaint alleging Rechtsverweigerung/Rechtsverzögerung against the cantonal court was admissible.
Extracted holding
The complaint was inadmissible because the appellant did not sufficiently show a violation of procedural rights or other federal law; the request also largely became moot in the changed procedural posture.
Extracted reasoning
After the earlier Federal Supreme Court decision, only review of the tax objection decision remained pending before the cantonal court, so the suspensive-effect request largely lacked subject matter. The appellant failed to comply with the duty to reason the complaint under Art. 42(2) and Art. 106(2) BGG.
