PARIS, Oct 11 (Reuters) - A French court on Thursday threw out a request by Swiss bank UBS to drop money laundering charges and limit trial proceedings to complicity in tax fraud, which carries lighter penalties.
Swiss bank UBS Group AG, its French unit and six executives face charges of aggravated tax fraud and money laundering in an investigation into allegations they helped wealthy clients avoid taxes in France.
Under French law, a defendant can on the first day of trial raise objections to the case going ahead on grounds that the constitution has been flouted. The court described the bank's arguments as "devoid of seriousness".
After seven years of investigation and aborted settlement negotiations, UBS will also answer allegations that it illegally solicited clients in France.
UBS, Switzerland's largest bank, said in a statement before the trial that the hearing would allow it to respond to "the often unfounded allegations that were frequently leaked to the media", but said it would reserve its arguments for the court.
If found guilty of money laundering, UBS could be fined up to 5 billion euros ($5.76 billion). French criminal law lets judges enforce fines as high as half the amount laundered and in this case prosecutors estimate that up to 10.6 billion euros was denied to the French tax authorities.
The bank could also face damages to the French taxman for the missing revenue, while its executives risk jail time.
UBS's lawyer Jean Veil told the court on the opening day that the French state was asking for 1.6 billion euros in damages, which he said was excessive.
