The US Supreme Court on Saturday cleared the way for the extradition of an American father and son accused of helping smuggle former automotive giant Carlos Ghosn out of Japan. The decision concludes the pair’s nearly year-long legal effort to avoid facing criminal charges in Japan.

On behalf of the court, Justice Stephen Breyer denied the 30-page emergency application for a stay pending appeal filed by Michael Taylor and his son, Peter Taylor. The denial came a day after their petition and without comment. The Taylors argued for the suspension of a decision by the US Court of Appeals for the First Circuit, which declined to intervene after the US State Department approved Japan’s extradition request.

The men are believed to have helped Ghosn, former Chairperson and Chief Executive Officer of the Nissan Motor Company, escape and flee from his court-monitored housing in Tokyo while facing financial crime charges. After a whistleblower came forward with serious financial misconduct allegations against Ghosn, Japanese authorities arrested him in 2018. Following his mysterious disappearance in 2019, officials issued an arrest warrant for the Taylors in early 2020. American authorities arrested them in Massachusetts in May.

The Taylors allegedly planned and executed Ghosn’s elaborate escape act. Ghosn boarded a bullet train to journey from Tokyo to Osaka, where he hid in a box meant to look like audio equipment. The box was then placed on a private jet and flown directly to his childhood home in Lebanon.

Prosecutors say the Taylors received over $1 million for their services in planning and carrying out the escape. In January 2020, the New York Times reported that Ghosn’s escape from Japan was the result of an extensive international planning process, organized by at least 15 operatives from around the world.

Ghosn is currently out of reach of Japanese authorities, as Japan and Lebanon do not have a formal extradition treaty. Interpol, however, placed him on its Red Notice list. Nissan announced a $90 million lawsuit on Saturday against Ghosn, who maintains his innocence.
