Janis Sharp has said she is "overwhelmed and incredibly happy" after the announcement that her son, British computer hacker Gary McKinnon, will not be extradited to the US.
Mr McKinnon, 46, who admits accessing US government computers but claims he was looking for evidence of UFOs, has been fighting extradition since 2002.
His mother told a press conference that Mr McKinnon "couldn't speak" when he heard the news.
Mr McKinnon, from Wood Green, north London, who has been diagnosed with Asperger's syndrome, a form of autism, faced 60 years in jail if convicted in the US.
