The High Court ruled on Monday that accused hacker Lauri Love will not be sent to America to face charges.
Love is accused of hacking into the FBI, the US Central Bank and NASA.
Love's legal team argued that extradition would not be in the "interests of justice" and he would be at a "high risk" of harming himself.
Love is living with Asperger's syndrome and depression.
He could still face charges in the UK.
