Question juridique clé
Whether the Federal Supreme Court could enter into the complaint despite non-payment of the cost advance.
Solution extraite
No. The complaint had to be dismissed at the threshold because the appellant neither paid the advance in time nor proved timely debit after a payment order.
Motifs extraits
After the request for an advance and a non-extendable grace period with warning of non-entry, the appellant failed to comply. Under the applicable BGG provisions, non-compliance required non-entry in the summary procedure.
