Social security insurance obligation ceases upon factual cessation of business, not just tax registry removal.

The Supreme Court dismissed the cassation appeal against a social security office decision regarding a self-employed individual's insurance obligation. The court clarified that while removing a business entry from the tax registry or noting a break in activity triggers insurance cessation, the social security office must independently verify the factual cessation of business rather than relying solely on the tax office's records. Consequently, the applicant's claim that her temporary illness justified a break in business activity was rejected because the medical certificate did not prove unfitness for work.
