Social security law ruling: lack of income from assisting a business partner does not exempt mandatory insurance coverage.

The Supreme Court dismissed the cassation appeal filed by a dental practitioner against a Social Insurance Institution decision ordering the return of benefits. The insured, who received a disability pension for a work-related illness, assisted her son in running a dental practice without receiving remuneration or generating income. The court held that the statutory requirement for mandatory social insurance applies regardless of whether the assistant generates income, thereby excluding the simultaneous receipt of a disability pension and an old-age pension.
