Questione giuridica chiave
Whether the unemployment benefit claim for January 2010 was forfeited because the required intermediate earnings certificate was not submitted on time.
Decisione estratta
Yes. The certificate was a necessary document for asserting the claim, and the fund had sufficiently and clearly warned of the forfeiture consequence.
Motivazione estratta
The claimant was repeatedly informed that all required AVIV forms had to be filed; the absence of the specific form could not be cured by a wage slip alone. The fund fulfilled its duty to inform, and the claimant had to procure and submit the missing form under his duty to cooperate.
