All remaining legal channels have been exhausted by a woman convicted of abducting her six-year-old son.
Kay Skelton and her father Dick Headley pleaded guilty to abducting the boy in August 2006 and were sentenced to community service and home detention.
The boy remained in hiding with his grandfather for five months in what was a custody dispute with the boy's father.
Skelton has now been told by the Supreme Court that her bid to ask the court to overturn her conviction has been dismissed, as the proposed appeal had no prospect of succeeding.
The court says Skelton failed to file any submissions, despite being granted a number of time extensions.
In June, the Supreme Court also refused to hear an appeal by Dick Headley.
