The woman at the center of the three-decade-old sex allegations against Oscar-winning film-maker Roman Polanski has filed court papers seeking dismissal of the charges against him.

Meanwhile, Polanski said Tuesday he has no plans to ever return to the United States, according to a new legal filing in his campaign.

Polanski, 75, has lived in exile in France since fleeing the United States in 1978 after pleading guilty to unlawful sexual intercourse.

Polanski admitted to having sex with a 13-year-old girl, and an arrest warrant against him remains in effect.

He has continued to direct films while living in self-imposed exile, including The Pianist, for which he won a best director Oscar.

The legal brief also said that Polanski is not required to be present for the court to rule on his motion to dismiss a three-decade-old rape charge.
