Russian-Uzbek billionaire Alisher Usmanov has filed a lawsuit against the bank UBS Europe SE in Frankfurt over what his lawyers said were unsubstantiated reports made about his transactions that triggered an investigation of him. Usmanov's lawyer, Peter Gauweiler, said in a statement on June 17 that German prosecutors and the Council of the European Union "have issued numerous erroneous decisions for which UBS is partly responsible, in particular, due to the use of its suspicious transaction reports as an instrument for the purposes of criminal prosecution and EU sanctions policy." UBS declined to comment.
