Questione giuridica chiave
Whether the subscription contract was a valid debt acknowledgment for the unpaid periodic charges of CHF 181.80.
Decisione estratta
Yes. The signed contract constituted a debt acknowledgment for the due periodic payments, and the debtor did not credibly show payment.
Motivazione estratta
The enforcement documents and invoice identified the period owed; the debtor only asserted payment without proof. The lower court correctly granted opening for the remaining balance of the periodic charges.
