The Tokyo District Court on Thursday found five doctors negligent and liable over the 2014 death of a 2-year-old boy due to an overdose with a sedative.

The court also said the five doctors from the Tokyo Women's Medical University Hospital should be liable for ¥60 million in damages, but because the parents of the victim already received ¥100 million in compensation from the hospital in 2015, they will not have to pay. The parents of the boy had been seeking damages totaling ¥180 million from the five doctors as well as two others.

The doctors administered the sedative, propofol, to the boy, Kosuke, after he underwent neck surgery in February 2014, even though its use for children who require artificial ventilation is banned in principle.
