A district court rejected an appeal made Thursday by the lawyers of former Nissan Motor Co. Chairman Carlos Ghosn to retract an earlier denial of bail.

The latest decision by the Tokyo District Court will further lengthen the confinement of Ghosn who has been detained for nearly two months following his initial arrest on Nov. 19 by Tokyo prosecutors for alleged financial misconduct.

It appears unlikely that Ghosn will be granted bail before the start of his trial, according to his chief lawyer, Motonari Otsuru. It could take at least six months for the trial to begin given the complexity of the case, which also involves documents in both Japanese and English, he said earlier.

In his first public appearance at a Tokyo court hearing on Jan. 8 to seek an explanation for his prolonged detention, the ousted chairman said, "I have been wrongly accused and unfairly detained based on meritless and unsubstantiated accusations."

Last week, Ghosn was freshly charged with aggravated breach of trust over the transfer of derivatives losses from his private asset management company to Nissan's books, as well as for payments allegedly made from a subsidiary of the Japanese automaker to a Saudi acquaintance of his in connection with the handling of the losses.

Ghosn's lawyers requested bail following the indictments but the court rejected the request on Tuesday.

Ghosn was initially indicted in December for underreporting his remuneration during the five years from fiscal 2010 and additionally charged last week with also underreporting his remuneration in the three fiscal years through March last year.
