Key legal question
Whether the complaint was admissible against non-final cantonal decisions and the enforcement office's attachment measure.
Extracted holding
The complaint was inadmissible insofar as it also challenged the enforcement office's attachment order and the lower supervisory authority's decision, because the Federal Supreme Court may only hear complaints against final cantonal decisions.
Extracted reasoning
Those parts were not directed against the last cantonal instance within the meaning of Art. 75 para. 1 BGG.
