A court on Thursday rejected prosecutors' request to extend the unusual detention of former Nissan Motor Co. Chairman Carlos Ghosn, boosting his chances of mounting a defense against claims that he understated his income.

The prosecutors appealed the Tokyo District Court's decision, but it was also denied. Legal experts believe the court will most likely accept bail requests.

The Tokyo District Court also rejected a request to extend the detention of his aide Greg Kelly, it said in a statement Thursday.
