The Israeli Supreme Court has rejected an appeal heard in July regarding accused child sex offender Malka Leifer's mental fitness to stand trial.
The unanimous decision delivered by the court on Wednesday renders her fit to continue to face her extradition trial, which is pending a ruling.
Ms Leifer is wanted in Australia for 74 charges of rape and child abuse from her time as principal at Melbourne's Adass Israel School.
Three Melbourne sisters' who were allegedly abused by Ms Leifer, who left for Israel after allegations arose in 2008, have been fighting to bring her back to Australia for almost a decade.
After countless delays in Israeli courts, the extradition hearing commenced in July, on the basis Ms Leifer was mentally fit to stand trial, as sanctioned by the court.
But her lawyers once again filed an appeal, even with the trial ongoing and a final psychiatric assessment already heard.
Longtime victim supporter Manny Waks released a statement following the appeal being rejected saying it was an expected decision.
"With Leifer’s legal avenues running out, we hope and expect that we now see her swiftly sent back to Australia where she will face her accusers," Mr Waks wrote.
"In their ruling, even the judges said that proceedings had dragged out 'much beyond what is reasonable."
The Zionist Federation of Australia President Jeremy Leibler also welcomed the decision.
"This unanimous rejection of her appeal by the Supreme Court helps restore faith in a system that allowed Leifer's alleged victims to wait for so long," Mr Leibler said.
"It is past time to bring Leifer back to face justice in Australia."
The Jerusalem District Court decision on her extradition is set to be announced on September 21.
Ms Leifer's lawyers, however, will have an opportunity to appeal.
