✔ 最佳答案
The lawyer is correct - it can't be estimated.
1. Regardless of the bus driver guilty or not, your friend can still sue the company.
Criminal wrongdoing does not equal civil wrongdoing.
2. Damage is based on actual damage. It is based on the doctor's comprehensive report on your friend's future earning ability, the cost of medical treatments, lost income, etc., which is directly resulted from the accident.
However, due to the severity of the accident, it is not difficult to "assume" that the damage award may excess HKD$1 Million, which the case will be proceed in the High Court.
