Partial disability requires inability to perform current job, not just chronic illness needing treatment.

The Supreme Court dismissed the Social Insurance Office's cassation appeal against a lower court ruling granting partial disability benefits to Wioletta K. The applicant argued that her chronic laryngeal conditions and need for constant treatment proved total inability to work, while the opposing party contended that the existence of such illnesses alone does not constitute partial disability. The court held that partial disability requires both biological impairment and economic inability to earn, meaning the applicant must be unable to perform her current job AND unable to take another job in her profession without retraining.
