Fugitive director Roman Polanski could face a tough US court battle next week as he seeks to resolve his four-decade rape case without spending more time in jail.
Polanski was arrested on US warrants in Poland and Switzerland in the last decade but both countries declined to extradite him.
Braun also argues that the Los Angeles court should give weight to the 2016 Polish extradition denial.
He later fled the United States, fearing a lengthy jail sentence if the agreement was overruled.
