Kernrechtsfrage
Whether the cantonal supervisory decision should be annulled.
Extrahierter Entscheid
Yes. The appeal was upheld and the supervisory decision was set aside.
Extrahierte Begründung
The debtor showed that no valid garnishment had been completed before 7 April 2012, because the wage garnishment notice and minimum-existence calculation did not contain the required debtor instruction under Art. 96 SchKG.
