Social security benefits in arrears retain independent character despite single payment under specific social insurance law.

The Supreme Court dismissed the cassation appeal filed by a claimant against a social insurance fund regarding her disability pension. The claimant argued that her pension had a permanent character and that the court should apply general pension laws instead of the specific work injury statute, while also contesting the suspension of payments due to her failure to attend medical examinations. The court ruled that the specific provisions of the work injury insurance law prevail over general pension laws and that the claimant's subjective belief regarding the pension's permanence did not constitute a valid excuse for missing the mandatory medical assessments.
