The Commission may, by notice in writing, request a person to whom this Division applies to provide to the Commission, within a period specified in the notice, any information that it considers would have been relevant:
(a) for the purpose of determining whether the person:
(i) was registered as a member of the SSA pension bonus scheme; or
(ii) in the opinion of the Commission, could have been so registered before becoming a war widow/war widower--pensioner had the person applied for that registration; and
(b) for the purpose of working out the bonus periods that the person would have accrued under the social security law:
(i) if the person was registered as a member of the SSA pension bonus scheme--if the person had made a claim for pension bonus under that law immediately before becoming a war widow/war widower--pensioner; and
(ii) if the person was not so registered but, in the opinion of the Commission, could have been so registered before becoming a war widow/war widower--pensioner had the person applied for that registration--if the person had been so registered from the earliest day that the person could have been so registered and, immediately before becoming a war widow/war widower--pensioner, had made a claim for pension bonus under that law.
