A Swiss court reversed its previous rejection of bail, saying it was now confident the large cash guarantee —$4.5 million — would compel Polanski to stay under house arrest with "constant electronic surveillance" at his chalet in the Swiss resort of Gstaad.
The court said it still saw him as a high flight risk, the AP reported.
Polanski was arrested Sept. 26 by Swiss authorities and is wanted by U.S. authorities for having sex with a 13-year-old girl in 1977. He fled the United States in 1978 for France after pleading guilty to one count of unlawful sexual intercourse with the girl.
"We will decide quickly on whether to order his release or file an appeal with the Federal Tribunal," Justice Ministry spokesman Folco Galli told the AP.
The decision to extradite the 76-year-old Oscar-winning director of The Pianist to Los Angeles is still pending.
