Questione giuridica chiave
Whether the document of 2 September 2003 constituted a valid debt acknowledgment binding the defendants
Decisione estratta
Yes, it was a debt acknowledgment in form, but it lacked a valid underlying cause binding the defendants.
Motivazione estratta
A debt acknowledgment reverses the burden of proof, but the underlying obligation must still exist and be valid. Here the defendants were not tenants and no valid transfer or cumulative assumption of debt bound them; the acknowledgment therefore had no valid cause.
