The court rejected all the charges except for one alleging a violation of economic intelligence, for having made public information about foreign entities in Lebanon, France, Germany, and the UK.
HSBC, which argued that he had illegally downloaded details from clients and accounts, welcomed the decision against Falciani, who was an IT worker at HSBC Private Bank (Suisse).
"HSBC has always maintained that Falciani systematically stole clients' information in order to sell it for his own personal financial gain,'' HSBC said in a statement.
