Supreme Court quashes lower court ruling for failure to specify exact underground work periods in social security benefit decision.

The Supreme Court quashed the appellate court's decision granting a mining pension to the applicant, ordering the case returned for retrial. The lower courts failed to meticulously detail the specific years, months, and days of underground work required by law, despite the applicant's employment history involving mixed surface and underground tasks. The court ruled that social security benefits dependent on specific contribution periods require precise calculation and disclosure of included and excluded timeframes in the judgment's reasoning.
