Former Nissan Motor Co. Director Greg Kelly should be exonerated of criminal charges for allegedly helping Carlos Ghosn underreport compensation, because he had no motive and no knowledge of any plans to repay the former chairman for reduced income, his lawyer said on the final day of court proceedings.

Prosecutors failed to prove that there was a conspiracy within the Japanese carmaker to conceal the auto executive’s remuneration, Yoichi Kitamura, Kelly’s defense attorney, said during closing arguments Wednesday at the Tokyo District Court.

Kelly, 65, was arrested the same day as Ghosn in November 2018 and has been in Japan ever since, seeking to prove his innocence in a trial that started a year ago. "The defendant, Gregory Lewis Kelly, is innocent,” Kitamura said.
