Rafael Nadal is scheduled to hear the outcome of his longstanding lawsuit
Nadal, 31, is suing Bachelot for £90,000 after she accused him of having a positive doping test.
Bachelot served as sports minister between 2007 and 2010 but her controversial comments came in March 2016.
She alleged on French TV that Nadal faked an injury in 2012, when he missed the final six months of the season due to knee problems, in order to hide a positive drug test.
In the seven months between Wimbledon in 2012 and February 2013, Nadal did not play.
The Spaniard has strongly denied that injury was the reason for his break – a fact he justified with medical records.

Nadal handed over medical records at a hearing last month which showed his long-term problems with knee tendinitis.
World No 1 Nadal didn’t attend the hearing but his lawyer Patrick Maisonneuve argued that Bachelot's comments were harmful to his reputation and potential ability to attract sponsors.
Maisonneuve said his client had “asked me to put to bed once and for all what Mrs Bachelot said by passing on to you his medical file”.
She too didn’t attend but her representatives argued damages be limited to a euro in a country where laws protecting freedom of speech are strong.
The 16-time Grand Slam champion never failed a drugs test and vehemently denies ever using a banned substance.
Rafael Nadal has strongly denied drug claims
He is also a strong advocate of tough punishments for drug users.
After Sharapova was found to have taken meldonium, a drug which increases endurance capabilities, Nadal called for a severe punishment.
“It is difficult to imagine that something like this can happen, but mistakes happen," Nadal said.
“She should be punished. I want to believe it is a mistake for Maria.
“She didn't want to do it but obviously it is negligence. She must pay for it.”
