Japan's top court said Thursday it has rejected an appeal by former Nissan Chairman Carlos Ghosn's lawyers against his extended detention after his fourth arrest on allegations of financial misconduct.

The decision upholds the extension of his detention through April 22 that was approved Monday by the Tokyo District Court.

The Supreme Court ruling was made Wednesday and conveyed to foreign media on Thursday.

Ghosn was first arrested in November and charged with under-reporting his retirement compensation and with breach of trust. He was released March 6 on bail, but was arrested again on April 4 on fresh allegations and sent back to detention.

Rearresting a suspect released on bail, which is allowed only after indictment, is rare and has triggered criticism of Japan's criminal justice system, in which long detentions during investigations are routine.

Ghosn, who led Nissan for two decades and is credited with turning around the company from near-bankruptcy, has denied any wrongdoing.

In a separate legal maneuver, the Tokyo District Court has rejected an appeal by Ghosn's lawyers questioning prosecutors' confiscation of video of security camera installed at Ghosn's apartment, Kyodo News reported Thursday. The court did not respond to calls after office hours.

Last week, Nissan's shareholders voted to remove Ghosn from the company's board.

In his video statement filmed before his arrest and released by his lawyers April 9, Ghosn accused some Nissan executives of plotting against him over unfounded fears about losing their autonomy to their French alliance partner Renault SA.
