Carlos Ghosn will get a chance Tuesday to make his case to the Tokyo District Court that he should be released on bail from his 50-day detention. But 9,500 km away in Paris, his future as head of Renault SA is increasingly in doubt.

The French government, the carmaker¡¯s biggest shareholder, is calling into question if Ghosn can remain at the helm of one of the country¡¯s most important manufacturers, according to a senior government official.

Ghosn would spend most of his time defending himself against accusations of financial improprieties rather than running a company, and his position at Renault is seen as unrecoverable, according to sources close to Renault¡¯s leadership team who asked not to be identified discussing internal company matters.
