Question juridique clé
Whether the supervisory authority could refuse to examine the complaint about the execution of the seizure by the requisitioned enforcement office.
Solution extraite
The complaint about the manner of executing the seizure had to be directed against the requisitioned office; the cantonal supervisory authority was not competent to review that execution.
Motifs extraits
In a requisition case, complaints about how the ordered seizure was carried out must be brought against the requisitioned office. Since Betreibungsamt B. carried out the seizure on request of Betreibungsamt A., the Graubünden supervisory authority lacked competence.
