The Swiss Federal Penal Court said in a brief statement on its website that it would make a decision on the appeal within the “next few weeks” after an exchange of written motions and would not give more information on the case in the meantime.
Polanski, 76, who has dual French and Polish citizenship, was arrested on Saturday on a US warrant by authorities in Switzerland, where the Chinatown director was set to receive a lifetime achievement award at the Zurich Film Festival.
His Swiss lawyer, Lorenz Erni, told Reuters Polanski would fight the extradition and that while the filmmaker was fine, the detention was very tough for him. Erni declined to comment on how long Polanski might remain in prison.
A Swiss justice ministry spokesman said on Monday it was theoretically possible that Polanski could be released on bail, although that was very unlikely.
The complex extradition process could take years if Polanski challenges it, US judicial sources said on Monday. US authorities have up to 60 days to make a firm extradition request.
Swiss Foreign Minister Micheline Calmy-Rey told a news conference in Berne that her office had not been informed in advance of Polanski’s arrest, which had “lacked finesse” and had looked bad.
Switzerland had acted in accordance with the law, but could have acted with more tact, as Polanski was in Switzerland to attend a film festival where the Culture minister was also due to speak.
Polish Prime Minister Donald Tusk urged moderation in the case, adding that while Polanski should be offered Polish consular help, ministers need not get involved.
“The case involves a great director but still, it is also a case of rape, of sex with a child,” Tusk said. “We should not bring politics into this or speak in patriotic tones.”
French consul general Jean-Luc Faure-Tournaire visited Polanski in jail on Monday and said he was being treated well.
“He thanks the many people who have expressed their support for him,” the consulate said in a statement.
The filmmaker, who won the best director Oscar for 2002 Holocaust film The Pianist, is wanted for fleeing the United States on the eve of his sentencing over a 1977 charge of having sex with a 13-year-old girl, to whom he also was accused of giving drugs and alcohol. — Reuters.
