Lever, who also holds Israeli citizenship, fled Australia in 2008 after accusations were brought against her, which she insisted on denying.
Australia was pressuring Israel to expedite the resolution of the lawsuit filed by Leifer, and its victims criticized the long judicial procedures in Israel.
Lever resisted her return to Australia, in various ways, including presenting evidence that she was mentally ill. This prolonged the ongoing case in Israeli courts since 2014.
Lever can still file another case before the Supreme Court challenging the approval of her extradition; But the court hinted that it might not hear the case.
