Carlos Ghosn: The Supreme Court of Japan rejects the appeal of Carlos Ghosn: report

The Supreme Court of Japan has rejected the appeal of Carlos Ghosn's lawyers against his detention, local media reported Saturday, annihilating the hopes of the former boss of Nissan to obtain early release.

The former 65-year-old mogul appealed to Japan's highest court, after lower court judges ruled that he could be interrogated for a period of 10 days until Sunday, because of allegations of financial misconduct.

But the court dismissed the appeal without explaining the decision, reported Jiji Press and Kyodo News.

Immediate confirmation of reports was not available.

On Friday, the Tokyo District Court had already extended his detention until April 22, as prosecutors continued to search him.

The authorities must then either lay formal charges, release him, or re-arrest him if they feel he has any other allegations to answer.

Prosecutors are investigating allegations that Ghosn siphoned about $ 5 million of funds transferred from Nissan to a dealership in Oman and spent that money on a luxury superyacht.

Ghosn has not been formally charged for these allegations.

But the tycoon is already facing three separate charges. Two of them involve millions of dollars in wages that would have been hidden from shareholders. The third charge is that he was seeking to transfer the losses badociated with personal investments to the books of the company.

Ghosn denied all allegations and criticized in a video message – presented on April 9 – what he termed a "conspiracy" in "harbading" Nissan executives fearing closer integration with French partner Renault.

The case has seduced Japan and the business world since the tycoon was arrested unexpectedly at the Tokyo airport on November 19 and was taken to the detention center.

He spent 108 days in an initial period of detention, under conditions that he did not wish for his "worst enemy", forced to sleep with the light on and forbidden to contact his relatives.

He then obtained a bond, accumulating $ 9 million for his freedom and subjecting himself to strict bail conditions, including not using the Internet or contacting a person related to the case.

But in another twist, he was then arrested again on a descent at dawn on 4 April for further interrogations.

Once welcomed as the savior of Nissan, Ghosn fights to restore his reputation. He was fired almost immediately from the head of the company and subsequently resigned from his position as Renault's boss while he was fighting the charges.

His lengthy detention has prompted criticism of the Japanese justice system as "hostage justice" by some, as suspects can be detained for a long time without formal charges.
