Former prosecutor Takeshi Tsuchimoto, now a professor of criminal procedure law at Hakuoh University Law School, criticised the decision to acquit Obara for the murder of Blackman by pointing to the conviction of Masumi Hayashi due to circumstantial evidence. The public prosecutor, however, appealed the Blackman-related verdicts, as crucial forensic evidence had not been heard at the original trial, and on March 25, 2008, an appeal trial commenced in the Tokyo High Court. Tokyo's High Court found Obara guilty on the counts of abduction, dismemberment and disposal of Blackman's body on December 16, 2008. In early December 2010, the Supreme Court of Japan rejected Obara's appeal and upheld his life sentence.
