Social security pension appeal dismissed; burden of proof lies with applicant for disability benefits.

The Supreme Court dismissed the cassation appeal against a lower court's refusal of a disability pension to Stanisław S. The applicant failed to prove a five-year employment period within the last decade and did not demonstrate that his disability arose within 18 months of his job termination. The court rejected the claim that the lower court erred in procedure or fact-finding, noting that the burden of proof rests on the applicant under the relevant social security law.
