Ex-UBS trader who had worked in Singapore cannot escape US case over Libor, says judge

NEW YORK (REUTERS) - A former UBS trader charged as part of a US investigation into Libor rate manipulation lost a bid to have the case dismissed on Monday, with a federal judge ruling that a fugitive from US justice had no right to mount a legal challenge.

US District Judge Paul Crotty in Manhattan said Roger Darin, a Swiss citizen, was "flouting judicial process" by remaining in his home country to avoid arrest while sending lawyers to ask the judge to dismiss the case. Switzerland does not extradite its citizens.

Prosecutors said Darin - who traded in short-term interest rates in UBS offices in Singapore, Tokyo and Zurich - conspired with fellow UBS trader Tom Hayes, who on Monday was sentenced in London to 14 years in prison after being found guilty of conspiring to rig Libor.

Darin's lawyers argued he was not a fugitive since he had never fled, let alone appeared, in the United States since the US Justice Department filed its criminal complaint in 2012.

But Crotty said his ruling was in line with "the realities of modern criminal prosecutions."

Hayes' case was the first to reach trial in a global inquiry that has led to several people being charged and some of the world's most powerful banks and brokerages paying around US$9 billion in regulatory settlements.

Libor, or the London interbank offered rate, is a short-term rate that underpins hundreds of trillions of dollars of financial products from mortgages to credit card loans.

According to US authorities, Darin conspired with Hayes to commit wire fraud by agreeing to submit yen Libor opinions to benefit Hayes' positions.

A Japanese subsidiary of UBS in 2012 pleaded guilty to wire fraud as part of a US$1.5 billion accord resolving US, UK and Swiss probes.

In resolving a similar investigation into the rigging of currency markets, UBS tself in May pleaded guilty and agreed to pay a US$203 million penalty for breaching a non-prosecution agreement over manipulation of Libor.
