Child killer Kathleen Folbigg’s final appeal against her convictions for killing her babies has been dismissed.
53-year-old Folbigg went to the Court of Appeal seeking to quash the 2019 outcome of a judicial inquiry by retired District Court Judge Reginald Blanch, which reinforced her guilt for the murders of Patrick, Sarah and Laura, and the manslaughter of Caleb at the family home in the NSW Hunter Valley between 1989 and 1999.
The children were all aged between just 19 days and 18-months when they died.
Folbigg has spent 18 years in jail after being convicted of killing her four babies and will now remain in jail to serve the remainder of her 40-year term, with a non-parole period of 30 years.
The convicted killer had been hoping that new scientific evidence would see her conviction overturned for the horrific crimes she committed.
Genomic testing had shown that at least two of her children likely died from previously undiscovered genetic mutations that led to heart complications.
The finding prompted a 14-page petition to the Governor of New South Wales, signed by 90 medical practitioners and science leaders, called for her immediate pardon and release.
The Court of Appeal dismissed Folbigg’s appeal application and ordered her to pay the legal costs of the NSW Attorney-General.
