Kernrechtsfrage
Whether the appellant fulfilled the contribution period for unemployment benefits through sufficiently proven insured employment and wage payments.
Extrahierter Entscheid
He did not prove with sufficient reliability that a contributory employment was actually exercised during the relevant period; the documents on wage payments were contradictory.
Extrahierte Begründung
Actual wage payment is not an independent condition, but in a critical case it is an important indicator of insured employment. Here the written records, account extracts, wage slips and receipts were inconsistent and did not establish a verifiable wage flow; therefore neither the contribution period nor the insured earnings could be reliably determined.
