“You can get the date of around Nov. 27, 2009 — Lai’s original due date — if you add the actual gestation period of 266 days to the date of her possible last ovulation on Mar. 5, 2009,” Yang said.
In an attempt to accurately pinpoint Lai’s conception date, the court subsequently ordered the hospital where Lai underwent her prenatal examinations to ascertain the date.
Judging from the length of the fetus and the development of her skull as shown in ultrasound records, the hospital concluded that Lai’s conception date should be Mar. 5, 2009, one day after Kuo and Chen’s divorce.
The judge accordingly ruled Kuo not guilty based on the hospital’s conclusion.
Commenting on the case, Yang said: “Wining a case by resorting to an accurate calculation of one’s ovulatory period not only is something I did not expect, but is also extremely rare in legal history.”
