Work accident disability percentage based on official tables cannot be reduced by pre-existing conditions.

The Supreme Court dismissed the cassation appeal against a labor court judgment regarding work accident compensation. The lower courts had reduced the official 30% disability rating to 9% because the plaintiff's heart attack was partly caused by his pre-existing hypertension. The Supreme Court ruled that the statutory disability percentage determined by official tables must remain unchanged regardless of the extent to which internal illnesses contributed to the accident.
