Social security applies to civil partnership partners only during personal business activity, not during illness-related pauses.

The Supreme Court dismissed the cassation appeal against a social security office decision regarding Teresa S.'s coverage status. The court held that social security obligations for civil partnership partners depend strictly on the personal conduct of business activities, not merely on the existence of a partnership entry. Although the partner was ill and unable to work personally, the court ruled that the legal presumption of activity persisted until a formal cessation was declared, rejecting the argument that illness automatically suspended the obligation.
