Questão jurídica principal
Which regulation applies to the calculation of a widow’s pension: the rule in force at the insured person’s death or a later rule?
Decisão extraída
The applicable regulation is the one in force on the day of the insured person’s death, when the beneficiary’s entitlement arises.
Fundamentação extraída
The right to survivor benefits arises at the insured person’s death; the pension calculation must therefore be governed by the regulatory framework then in force.
