TOKYO (AP) — Nissan's former chairman, Carlos Ghosn, appeared in a Japanese courtroom Thursday for a hearing ahead of his trial on accusations of financial misconduct.

It was the first of a series of hearings to iron out logistics for Ghosn's actual trial. The trial date has not been set, and experts say it could be months away.

Ghosn, who led the Japanese automaker for two decades, was arrested in November and charged with underreporting his income and breach of trust. He was released on bail in March, rearrested in April on fresh accusations and then released again on bail on April 25.

Ghosn insists he is innocent and says he was targeted in a "conspiracy" by others at Nissan Motor Co.

Nissan, which is allied with Renault SA of France, has seen profits nose-dive amid the fallout from Ghosn's arrest.

Ghosn has hired a strong legal team as he fights to clear his name. One of his top lawyers, Junichiro Hironaka, was seen walking into the courtroom Thursday with Ghosn.

One of the conditions of Ghosn's release on bail is that he is forbidden to contact his wife. Prosecutors say that's to prevent evidence tampering.

Ghosn's lawyers challenged that restriction, saying it is a violation of human rights, but the Supreme Court rejected their appeal Tuesday.

The lawyers can appeal again to have the restriction removed.

In a briefing Thursday, Deputy Chief Prosecutor Shin Kukimoto welcomed the Supreme Court's decision.

"For married people to be together is important, but I feel there was enough reason for the Supreme Court to support us in this restriction," he said.

Kukimoto declined comment on the hearing, which was closed to reporters and the public.

Kukimoto also said the maximum penalty upon conviction of all 15 counts of the charges Ghosn is facing is 15 years in prison and a fine of 150 million yen ($1.4 million).
