Polanski lawyers want testimony unsealed

Say they need to submit transcripts to Swiss authorities

Roman Polanski's lawyers want a Los Angeles judge to unseal secret testimony by the original prosecutor in the director's 33-year-old sex case.

In a motion to be filed Thursday, the attorneys say transcripts of testimony by retired Deputy District Attorney Roger Gunson are needed urgently to submit to Swiss authorities pondering whether to extradite Polanski to the U.S. after decades as a fugitive.

Gunson testified this year in what is known as a conditional examination. Such proceedings preserve testimony of a witness who might not be available for future hearings.

The motion says the transcripts will prove the extradition request is based on false and incomplete statements by the Los Angeles district attorney's office.
