Three doctors held a debate Wednesday in a medical malpractice suit before the Tokyo District Court in the first application of the "conference debate formula" intended to gain a fairer outcome and shorten court proceedings.

The three expert witnesses, specialists in the circulatory system and anesthesiology, first presented prepared opinions on an electrocardiogram record and three other items related to the case of a man who died after having surgery to remove a swelling on his neck.

Two of the man's relatives are demanding compensation of some 34.5 million yen from the hospital where the operation took place.
