An Australian court will consider overturning a woman’s convictions for killing her four children, months after she was pardoned for the crimes due to new evidence that the siblings had died of natural causes, a government inquiry has reported.

Overturning Kathleen Folbigg’s convictions would end a legal battle that has reached the highest level of Australia’s court system to clear her of responsibility for her children’s deaths, which happened over a decade between 1989 and 1999.

Ms Folbigg, 56, was freed in June after spending 20 years in prison when the New South Wales state government pardoned her on three counts of murder and one of manslaughter.

The pardon was based on the interim recommendations of a state inquiry into new scientific evidence that created reasonable doubt that Ms Folbigg had smothered her children, as prosecutors had alleged at her trial.

The inquiry’s final report recommended on Wednesday that the state court of criminal appeal should consider clearing Ms Folbigg’s criminal record.

Ms Folbigg’s lawyer, Rhanee Rego, welcomed that recommendation as “another significant positive milestone in Kathleen’s 24-year journey to clear her name”.

“Today, and every day, Kathleen’s thoughts are with her children,” Ms Rego added.
