Key legal question
Whether the unemployment fund had to recalculate benefits after the claimant produced the equivalence certificate belatedly.
Extracted holding
The certificate was a valid new means of proof; the fund had to reassess the insured gain and recalculate benefits for the relevant periods.
Extracted reasoning
The failure to produce the certificate earlier was excusable because the claimant had searched for it and only found it later in Argentina. Revision is not barred by the three-month forfeiture rule when a new, decisive piece of evidence could not previously be produced with due diligence.
