Social Security Board cannot initiate pension rights review ex officio after final pension grant decision.

The Supreme Court dismissed the Social Security Board's appeal, ordering the reinstatement of the applicant's pension rights. The Board had unilaterally suspended payments after re-evaluating employment records, claiming the applicant did not work under special conditions. The Court ruled that once a pension right is legally established, the Board lacks authority to initiate a new review process without new evidence or undisclosed circumstances. Consequently, the suspension was deemed unlawful as it violated statutory prohibitions on ex officio proceedings.
