The Russian Paralympic Committee (RPC) has launched an appeal against a decision to uphold a ban on their athletes competing at next month’s Rio Games.
The RPC filed the appeal in the Swiss Federal Court against the ruling by the Court of Arbitration for Sport (CAS).
"The appeal has been launched in the Swiss court," the Interfax news agency quoted RFC president Vladimir Lukin as saying on August 26.
Earlier this week the CAS, sport's highest tribunal, rejected an RPC appeal against the ban issued by the International Paralympic Committee (IPC).
The IPC decision followed revelations of widespread cheating in Russian sport that ignited a doping scandal that has threatened to split the Olympic Movement.
The Rio Paralympics run from September 7-18.
