Just after four days of former International Monetary Fund (IMF) chief Dominique Strauss-Kahn's fortune turning brighter, the French economist and politician will again have to face some more or many more court proceedings as a new case of sexual assault will be filed against him.

French writer Tristane Banon accused Kahan of trying to rape her during a 2002 book interview in a flat in Paris.

With France debating his possible return to presidential politics, Strauss-Kahn swiftly hit back at author Tristane Banon's plans to take him to court, labeling her account imaginary and countering with his own plans to file a criminal complaint of slander, the Associated Press reported.

Last week a New York court released Kahan from house arrest without bail as the prosecutors gave him a benefit of doubt regarding the credibility of the maid who accused him of a sexual assault and attempt to rape.

The maid, within a day of the alleged rape attempt was recorded speaking on the phone with a man jailed for possessing 400 pounds (180 kilograms) of marijuana and discussing the benefits of pursuing charges.

Law enforcement officials were surprised and had to be concerned when the conversation was translated from Fulani - dialect spoken in the maid's native.

She says words to the effect of, 'Don't worry, this guy has a lot of money. I know what I am doing,' the New York Times quotes one of the officials as saying.

With the new case by the French writer Strauss-Kahn's return into French presidential politics will become very difficult.
