In a Tokyo court on Monday, an American father and son pleaded guilty to allegations that they illegally assisted former Nissan Motor Co Ltd (7201.T) Chairman Carlos Ghosn depart Japan in late 2019 disguised in a box on a private airplane.

When the judge inquired if there was anything incorrect with the allegations filed by the Tokyo Prosecutors’ office, US Army Special Forces veteran Michael Taylor and his son Peter said no. It was their first appearance before the Court in this case.

Father and son were extradited to Japan from the United States in March and are being jailed in the same Tokyo jail as Ghosn. They could spend up to three years in prison if convicted.

Prosecutors claim the pair earned $1.3 million in exchange for assisting Ghosn in fleeing Japan.
