The Osaka High Court on Tuesday decided to send a robbery case involving a Nigerian man who was sentenced to six years in prison back to a lower court.

The 39-year-old man, who has already served his prison sentence, made an appeal for retrial after the Kobe District Court's Himeji branch in Hyogo Prefecture rejected a previous appeal to reopen the case in March 2014.

Presiding Judge Akiyoshi Sasano of the appeals court decided to send the case back to the Kobe court, saying deliberations at the branch court had not been sufficient.
