All appeals are dismissed.

The grounds of appeal are examined.

In light of the relevant legal principles and evidence, the lower court did not err by misapprehending the legal principles on the reinforcement of confessions, and the joint principal offender, contrary to what is alleged in the grounds of appeal.

In addition, pursuant to Article 383 subparagraph 4 of the Criminal Procedure Act, only in cases where death penalty, life imprisonment, or imprisonment with or without prison labor for more than ten years has been imposed, a final appeal may be filed on the grounds of unfair sentencing. As such, in this case where Defendant C was sentenced to a minor punishment, the argument that the amount of punishment is unfair is not legitimate grounds for final appeal

Therefore, all appeals are dismissed. It is so decided as per Disposition by the assent of all participating Justices on the bench.
