Questão jurídica principal
Whether the declared right to a partner pension could be assessed under the 2008 or 2009 pension rules.
Decisão extraída
The 2009 rule applied, because the relevant insured event for a survivor pension is the death of the insured and the court must decide under the law in force when it rules on the declaratory claim.
Fundamentação extraída
For survivor benefits, the applicable rules are those in force at the time the decisive event occurs; a declaratory action does not alter that principle. Since the insured death had not occurred, the amended regulation in force at decision time governed.
