World Athletics is to sue Lamine Diack and his co-defendants for £35million.
The ex-head of the sport's governing body, formerly known as the IAAF, was in a Paris court on Monday.
His trial was adjourned until June following a dramatic late submission of evidence from his co-accused son.

On an afternoon high on drama but low on progress, Diack, 86, pleaded personally to be allowed to visit his 100-year-old brother in Senegal in the wake of the delay.
However, that request was rejected — and there could be further pain for the Senegalese with his former employers expected to demand tens of millions in damages for loss of revenue and reputational damage.
Sportsmail has learned that World Athletics will claim they are victims of the alleged offences and have lost out heavily financially. The £35m claim is a total of the costs laid against each of the six defendants.
Diack, who has been banned from leaving France for the past four years, had to surrender his passport and pay £430,000 bail. He faces corruption, money-laundering and breach of trust charges amid claims he took cash from Russian athletes to cover up doping offences.

The long-awaited trial, which is likely to send shockwaves through the world of sport, was due to start on Monday.
But three files of new documents which landed at the last minute — relating to a testimony Papa Massata Diack unexpectedly gave in Senegal — prompted a delay.
Parties asked for more time to review the fresh material and the case was effectively adjourned until June.
Diack Jnr remains in the west African country, shielded from extradition to France.
