The Singapore race-fixing scandal, which has plunged the world's most glamourous sport into a bitter spiral of recriminations and resignations, will push Formula One's credibility to the brink tomorrow.
It will also go a long way in helping disgraced paddock superpower Renault decide whether or not it really wants to continue in a sport which bleeds 300 million euros from its stretched budget every year.
The French team hope that the resignations of flamboyant team principal Flavio Briatore and engineering chief Pat Symonds, following allegations they ordered ex-driver Nelson Piquet to deliberately crash in Singapore in 2008, will guarantee clemency when the World Motor Sports Council meets.
Having admitted they will not contest the charges against them, the likelihood is that a heavy fine and a points deduction will be the preferred sentence rather than outright banishment from the championship.
However, even that hasn't stopped the clamour for blood from respected voices within a sport which, in the aftermath of other recent acts of skullduggery, are exhausted by the damage caused to F1's image.
