Secret evidence given by the original prosecutor in Roman Polanski`s three-decade old illegal sex case will not be disclosed.
Los Angeles Superior Court judge Peter Espinoza turned down a request from the Rosemary`s Baby director`s lawyers to unseal transcripts.
The judge said the material would be made public only if Polanski returned to the US for a hearing and the retired prosecutor, Roger Gunson, was unavailable to give evidence in person.
"We continue to be bogged down in the question of whether he will ever return," the Daily Express quoted Judge Espinoza, as saying.
Polanski, 76, pleaded guilty in 1977 to having illegal intercourse with a teenaged girl but fled to France before his sentence could be pronounced.
He was arrested last September in Switzerland and currently remains under house arrest at his chalet in the Swiss resort of Gstaad.
