Deciding the verdict in the Lauren Dickason trial would've been an extremely difficult decision for any jury.
The 42-year-old has been found guilty of murdering her three daughters at their Timaru home in 2021.
Dickason pleaded insanity, caused by postpartum depression.
The Criminal Bar Association's former president Gary Gotlieb told Kate Hawkesby it was a case of having to weigh up the different views of experts.

Dickason has been remanded to Hillmorton Hospital, before her sentencing.
