Social security court dismisses disability pension claim when medical records from the relevant period fail to prove prior disability onset. The Supreme Court rejects the appeal, ruling that evidence must come from the specific time of disability onset for self-originating conditions.

The Supreme Court dismissed the cassation appeal filed by Jadwiga P. against the Social Insurance Institution regarding her disability pension claim. The applicant argued that medical certificates from 1996 should have established her disability as occurring earlier than the expert opinion indicated. The court ruled that for self-originating conditions, evidence must derive from the specific period of alleged disability onset, and since no such documentation existed prior to 1988, the lower courts correctly relied on the 1988 expert opinion.
