Questão jurídica principal
Whether the old or revised IVG rules govern the onset of the pension entitlement and pension commencement
Decisão extraída
Because the disputed insured event arose before 1 January 2008, the former rules on entitlement and pension commencement apply.
Fundamentação extraída
For pre-2008 insured events, the decisive point is the occurrence of the insured event, not the later date of application; the lower court therefore relied on the wrong temporal regime.
