All appeals are dismissed.

The defendants' grounds of appeal are examined together.

The judgment below

In light of the records, the court below is just in maintaining the judgment of the court of first instance ordering collection of KRW 755,755,000 against Defendant A for reasons stated in its holding, and there is no error in matters of law by misapprehending the legal principles on collection of penalty, accomplice, and contract, or by violating the principle of proportionality and equality.

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. Thus, in this case where Defendant B was sentenced to minor punishment, the argument that the amount of punishment is unfair is not a legitimate ground 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.
