Questão jurídica principal
Whether the cantonal court had to obtain additional archived files from the bankruptcy office to clarify alleged waiver declarations.
Decisão extraída
The court had sufficiently complied with the investigative duty; the new fax did not show an obviously incomplete or arbitrary fact-finding.
Fundamentação extraída
The instructions to the bankruptcy office were clear and specific, and the later fax did not make it more likely that relevant waiver declarations existed and had been withheld.
