Exiled director Roman Polanski is making a new push to finally put to rest his decades-old child rape case — and return to the United States, his lawyer told The Post on Thursday. 
 
 The “Chinatown” director’s attorney, Harland Braun, has requested that a Los Angeles judge unseal secret testimony that allegedly proves Polanski’s longtime contention that the judge in the 1977 case reneged on a deal for him to spend 42 days at Chino State Prison in Chino, Calif. 
 
 Polanski completed the stint in the lockup and underwent psychiatric evaluation — and Braun now wants the court to honor the plea deal defense attorneys struck with the original LA prosecutor in the case, retired Deputy District Attorney Roger Gunson. 
 
 “I believe there is no current excuse or justification for keeping DDA Roger Gunson’s sworn testimony under seal,” Braun wrote to Judge Scott Gordon in a February 6, 2017, letter obtained by The Post. 
 
 “The truth is that the sealing of the Gunson statement makes it appear that someone fears its contents.” 
 
 The 83-year-old Polanski was accused of drugging and raping a 13-year-old girl at the home of actor Jack Nicholson on March 10, 1977. Polanski had lured her there on the pretext of photographing her for French Vogue. 
 
 The late Judge Laurence Rittenband initially signed off on the plea deal, but had a sudden change of heart and ordered Polanski to spend up to 50 years behind bars. 
 
 Polanski fled the United States and has lived in Paris, France, ever since as a fugitive. 
 
 In 2009, Polanski was captured while traveling through Zurich, Switzerland. He was jailed for over 300 days as US authorities tried unsuccessfully to extradite him. 
 
 Braun has been working with Los Angeles prosecutors to resolve the case so that Polanski can travel freely throughout the world. ||||| FILE - This Feb. 25, 2015 file photo shows filmmaker Roman Polanski during a break in a hearing concerning a U.S. request for his extradition over 1977 charges of sex with a minor, in Krakow, Poland....

 LOS ANGELES (AP) — A Los Angeles judge on Monday rejected Roman Polanski's bid to end his long-running underage sex abuse case without the fugitive director appearing in court or being sentenced to more prison time. 
 
 Superior Court Judge Scott M. Gordon refused to address how Polanski would be sentenced if he returned to the U.S. after 40 years abroad. He noted that other courts, including a California appellate court, have ruled that the Oscar winner is a fugitive and must return to Los Angeles for sentencing. 
 
 "There is no sufficient or compelling basis for reconsideration of these issues," Gordon wrote. 
 
 Polanski was charged with six felonies in 1977 after he was accused of plying a 13-year-old girl with champagne and part of a sedative pill, then raping her at actor Jack Nicholson's house. 
 
 Polanski pleaded guilty to unlawful sex with a minor, but he fled Los Angeles on the eve of sentencing in 1978. He has sought to resolve the case several times without personally appearing in court. 
 
 His travel has since been confined to three countries: France, Switzerland and his native Poland. 
 
 The victim has said she forgives the "Rosemary's Baby" director and believes the case should end. 
 
 Polanski, 83, has long contended that he is the victim of judicial misconduct because a now-deceased judge who handled the case suggested in private remarks that he would renege on a plea bargain and sentencing agreement. It called for no more time behind bars for the director after he spent 42 days in a prison undergoing a diagnostic screening. 
 
 Polanski's lawyer, Harland Braun, said Gordon's order failed to address what he called the central issue in the case — misconduct by several previous judges who handled the case. 
 
 Polanski contends emails show that several judges had discussed how Polanski had to return to Los Angeles for sentencing. 
 
 "It seems like this just another cover-up," Braun said in an interview. 
 
 He said his efforts were aimed at seeing if the judicial system could fix previous errors in the case, and whether it was "capable of healing itself." 
 
 "In that regard, Judge Gordon proved that he cannot," Braun said. 
 
 Gordon's ruling says Polanski and Braun had "not presented sufficient credible, admissible evidence or legal arguments to warrant the requested relief." 
 
 Previous rulings have stated that the only way Polanski can address his allegations is to return to Los Angeles for his sentencing hearing. That would likely involve him being arrested and serving additional time behind bars while he awaited a hearing. 
 
 Braun has said Polanski's confinement in jail and house arrest in Switzerland during a failed extradition effort in 2009 and 2010 meant the director has already served his sentence. 
 
 The ruling came two weeks after Gordon convened a hearing to address several requests by Polanski's lawyer. Los Angeles prosecutors, who declined to comment on Monday's ruling, vehemently opposed any ruling that would end the case without Polanski's appearance in court. 
 
 Deputy District Attorney Michele Hanisee said Polanski was asking Gordon to give a "wealthy celebrity different treatment than any other fugitive." 
 
 Polanski won an Academy Award for best director for his 2002 film "The Pianist" and was nominated for 1974's "Chinatown" and 1979's "Tess."

– It's been 40 years since Roman Polanski set foot on the US mainland, but the disgraced director is said to want to square things up and come back to America without facing jail time, TMZ reports. What needs squaring: his punishment for raping a 13-year-old girl in 1977 at Jack Nicholson's house. Lawyer Harland Braun reportedly wants long-sealed testimony in the Polanski case opened to prove that Polanski had cut a deal to spend just 48 days behind bars for the sexual assault. But when the director of Rosemary's Baby was released after serving 42 days, which included psychiatric evaluation, the judge (now deceased) who'd reportedly signed off on the deal allegedly had a change of heart and decided 50 years in prison was a more just punishment. Polanski fled to Paris, where he's been living as a fugitive since, shortly after he agreed to plead guilty to unlawful sexual intercourse and right before his sentencing, per Page Six. A Polish court ruling in a recent Polanski extradition case said Polanski, now 83, had honored his punishment with his original stint behind bars, prompting Braun to call for a Los Angeles County Superior Court to do the same. (Polanski was picked to lead the jury for France's equivalent of the Oscars this month—and women's rights advocates aren't happy.)
