Dominique Strauss-Kahn, the former IMF chief who has successfully fought a handful of accusations linked to his "libertine" lifestyle, will be learning whether charges for aggravated pimping will be dropped.
An appeals court in the northern French town of Douai decides today whether to agree to Strauss-Kahn's demand to annul the charges linking him to a suspected prostitution ring run out of a luxury hotel in Lille.
Two of the four people implicated have asked that charges be dropped.
Lawyers for Strauss-Kahn, 63, claim the investigating judges have not been impartial.
The economist admits to attending "libertine" gatherings but denies ever knowing that some women present were paid.
New York prosecutors dropped charges of sexual assault against Strauss-Kahn by a New York hotel maid in May 2011.
