Filmmaker Roman Polanski will not be extradited to the United States until courts in Los Angeles have decided whether he must attend his trial in person.
The Swiss justice office said on Friday that it would be pointless to extradite Polanski while he is still trying to get his case heard in absentia.
The Franco-Polish director fled the US in 1978 after pleading guilty to unlawful sexual intercourse with a minor. He was picked up by Swiss authorities in September at Zurich airport.
He then spent two months in a Swiss prison but after posting a large sum in bail he was transferred to house arrest in his chalet in the Swiss resort of Gstaad in December.
His latest film, The Ghost Writer, was premiered at the Berlin Film Festival on Friday.
