Supreme Court dismissed cassation for failure to prove procedural error regarding non-notorious facts.

The Supreme Court dismissed the cassation appeal filed by Aleksander W. against a lower court decision that rejected his claim for a work accident. The appellant argued that the lower court erred in treating the defendant's act of removing metal shavings with a match as a well-known fact, whereas the Court held such personal health precautions are not notoriety. The Court reasoned that individual reactions to eye injuries vary and cannot be assumed known to all reasonable people, thus requiring expert evidence rather than judicial presumption.
