Supreme Court rules 25 half-doubled miner days equal one month for pre-1981 pension eligibility.

The Supreme Court dismissed the Social Insurance Institution's cassation appeal, upholding the lower court's decision granting the miner a pension. The dispute centered on whether 2,320 half-doubled work days equaled the required 25 years of service, with the insurer arguing for a 24-year total. The court ruled that the established legal rule of dividing half-doubled days by 25 (rather than 30) correctly calculated the tenure as 25 years and 3 days.
