Dr. Mak Wan-ling was found guilty of manslaughter by gross negligence for administering an experimental immunity boosting therapy.

A High Court jury on 1st December 2020 returned the unanimous verdict against Dr. Mak in her second trial on the matter, in which she was accused of unlawfully killing a Madam Chan by gross negligence, through breaching a duty of care she owed to Chan, by performing an injection without obtaining proper consent and ensuring the blood product infused was properly handled and free of contamination.

In the first trial in 2017, a different jury failed to reach a verdict in her case while convicting her two co-defendants – her boss Dr. Stephen Chow Heung-wing, and laboratory technician Chan Kwun-chung.

Update as of 8th December 2020:  After hearing counsel submissions on mitigation, the High Court sentenced Dr. Mak to an imprisonment of 3.5 years, whereas the co-defendants were sentenced previously to 12 and 10 years respectively (pending appeal).

The Defendant was represented by Deanna Law led by Peter Duncan S.C., instructed by Howse Williams.
