Questão jurídica principal
Whether the debtor's domicile had to be assessed at the time of issuance or at the time of service of the summons.
Decisão extraída
The relevant date is the date of service of the summons, not the earlier date of issuance.
Fundamentação extraída
Issuance of the payment summons is not yet an enforceable debt-collection act; only service starts the proceedings and can be challenged.
