Social Insurance Fund validly checks employment contract validity to determine social insurance coverage eligibility.

The Supreme Court dismissed the cassation appeal filed by Urszula M. and Henryk M. against the Social Insurance Fund's decision denying them social insurance benefits. The court found that the Fund was legally authorized to verify the validity of the employment contract to establish whether the applicant was covered by social insurance. The court ruled that the specific procedural article cited by the appellants does not apply to this administrative verification process, which concerns insurance status rather than the substantive validity of the civil law contract itself.
