Switzerland's supreme court on Monday gave authorities the green light to hand over details of cyclist Jan Ullrich's Swiss bank accounts to German magistrates examining doping-related offences.
The Federal Tribunal rejected an appeal by the 1997 Tour de France winner against the judicial assistance from Switzerland, where Ullrich was resident and licensed with the Swiss cycling federation.
Ullrich retired in February having been sacked by Team T-Mobile last year when he was linked to the Spanish Operation Puerto doping investigation, which has also engulfed several other riders since May 2006. The German has always denied being involved in the doping network uncovered by police in Spain.
Magistrates in Bonn are investigating allegations of fraud against Ullrich, following a legal complaint by T-Mobile about €1.3 million in advertising revenues paid to the rider in 2004 and 2005. T-Mobile said his contracts included clauses ruling out doping offences.
Swiss banking secrecy laws can only be lifted in criminal investigations.
