The court rejected an appeal by HSBC that charges first brought in April for facilitating tax fraud and illegal practices be dropped, sources told AFP.
Investigating magistrates accuse HSBC of failing in its supervisory role over its Swiss unit HSBC Private Bank which is suspected of having set up tax fraud schemes for its customers, mostly French.
"We are disappointed by the outcome of the appeals procedure," HSBC said in a statement. "We will continue to defend ourselves vigorously."
