NEW YORK, July 19 (Reuters) - A U.S. appeals court on Wednesday overturned the convictions of two former Rabobank RABO.UL traders in the first U.S. criminal appeal related to worldwide probes into the manipulation of the interest rate benchmark known as Libor.

The 2nd U.S. Circuit Court of Appeals in New York said the constitutional rights against self-incrimination of the former traders Anthony Allen and Anthony Conti, both from Britain, had been violated.
