Social security appeal dismissed as inadmissible; dispute concerns contribution base, not insurance obligation eligibility.

The Supreme Court dismissed the cassation appeal as inadmissible because the dispute concerned the calculation base for social security contributions rather than the obligation to insure. The medical care organization argued that the employee's income from a contract for work should be excluded from the contribution base, while the Social Insurance Institution maintained it should be included alongside the salary. The court ruled that since the issue was purely about determining the contribution base under Article 2(3) of the Social Insurance Act, Article 393(5) of the Code of Civil Procedure bars cassation in such matters.
