Jerusalem The Jerusalem District Court has ruled that a new psychiatric report is needed to assess if former Melbourne school principal Malka Leifer is fit to face an extradition trial over child sex abuse allegations.

Judge Chana Miriam Lomp on Monday presented a distant deadline of December 10 for the new assessment to be filed by three psychiatrists, in order for the court to decide if Leifer is truly mentally unfit, or faking her illness.

Now at hearing 57, the case to try and bring the former principal of the Ultra- Orthodox Adass Israel school in Elsternwick in Melbourne's south-east back to Australia to face 74 charges of rape and child sex abuse has met countless delays.

Judge Lomp in court said the evidence she had seen hadn't reached a significant benchmark to automatically state that Leifer had been feigning her illness and therefore was fit enough to face justice.
