Key legal question
Whether the arrest was void because no attachable assets existed at Bank Z.
Extracted holding
The complaint failed because the debtor did not substantiate the claim of a 'empty' arrest; the bank documents and account extract did not compel a finding of nullity.
Extracted reasoning
The alleged lack of assets was based on evidence assessed by the cantonal court. The later bank letters were inadmissible as novelties, and the debtor did not sufficiently challenge the appellate court's reasoning concerning the portfolio assets and the account balance.
