US government attempts to extradite from Britain a man accused of child sex crimes have been blocked by the High Court.
Two judges sitting in London allowed an appeal against extradition by fugitive Shawn Sullivan, 43, after the American authorities refused to give an assurance that he would not be placed on a controversial sex offenders treatment programme in Minnesota.
Sullivan has been described as one of the US's most-wanted alleged sex criminals, and has also been convicted of sexually assaulting two 12-year-old girls in Ireland.
His lawyers argued he could be declared "sexually dangerous" and placed on the US programme without a trial and with no hope of release.
Lord Justice Moses and Mr Justice Eady ruled on June 20 there was a real risk that, if extradited, Sullivan would be subjected to an order of civil commitment to the treatment programme in a "flagrant denial" of his human rights.
The judges then gave the US government a last opportunity to provide an assurance that there would be no commitment order made.
Lord Justice Moses announced it had been confirmed by the Americans in a post-judgment note that "the United States will not provide an assurance", and Sullivan's appeal under the 2003 Extradition Act was therefore allowed.
"The appellant will be discharged from the proceedings," said the judge.
Sullivan, who has joint Irish-US nationality, is wanted to stand trial for allegedly abusing three American girls in the mid-1990s.
His counsel Ben Brandon said at a one-day hearing in April that no one had been released from the treatment programme, operated by the Department of Human Services in Minnesota, since it began in its current form in 1988.
