The son of ex-world athletics chief Lamine Diack, Papa Massata Diack, is set to appeal his life ban from athletics.
Diack is seeking to overturn the decision to ban him at The Court of Arbitration for Sport.
The former consultant for the world athletics governing body, IAAF, is a subject of an Interpol notice.
His home country Senegal has rejected a request for his extradition.
Mr Diack is accused of trying to solicit bribes worth hundreds of thousands of pounds by blackmailing athletes who had failed drug tests.
He has denied the accusations.
His father is also being investigated over allegations he took payments for deferring sanctions against Russian drugs cheats while head of the IAAF.
