It concerned the deaths of her four infant children Caleb, Patrick, Sarah, and Laura – each of whom died suddenly between 1989 and 1999, aged between 19 days and 18 months. Prosecutors at her trial alleged she had smothered them.

The case relied on circumstantial evidence, using Ms Folbigg’s diaries – which were never examined by psychologists or psychiatrists – to paint her as an unstable mother, prone to rage.

In 2003, she was sentenced to 40 years in jail for the murders of Sarah, Patrick and Laura, and the manslaughter of Caleb.

It was later downgraded to 30 years on appeal, but Ms Folbigg lost a string of legal challenges that sought to overturn her convictions.

Earlier this year, a landmark inquiry into her case concluded there was reasonable doubt over her guilt, due to scientific findings that her children could have died of natural causes because of incredibly rare gene mutations.

And it was that “substantial and extensive body” of new evidence which led to Ms Folbigg being cleared of all charges on Thursday, Chief Justice Andrew Bell said.

Ms Folbigg’s legal team confirmed they would now seek compensation on her behalf, but did not say how much.
