Question juridique clé
Whether alleged defects in service of the legal-opening decision could be reviewed in debt-enforcement complaint proceedings
Solution extraite
No; such objections had to be raised in the remedy against the legal-opening decision itself, not in supervisory complaint proceedings.
Motifs extraits
The complaint under Art. 17 SchKG reviews only acts of enforcement organs, not issues from the judicial legal-opening procedure or service of that judgment.
