All three athletics officials banned for life by the IAAF ethics commission in January for bribery and extortion to cover up a Russian doping case have appealed to sport's highest court.

The Court of Arbitration for Sport says "all seek to have their life bans from involvement in the sport of track and field annulled."

The three are: Papa Massata Diack of Senegal, and Russian officials Valentin Balakhnichev and Alexei Melnikov.

Diack is the son of former IAAF President Lamine Diack and was the governing body's marketing consultant. He is the subject of an Interpol notice seeking his arrest for questioning in France.

Balakhnichev was the long-time president of the Russian athletics federation and former IAAF treasurer. Melnikov was head coach of Russian distance runners and race walkers.
