All appeals are dismissed.

The costs of appeal are assessed against the Defendants.

1. As to the grounds of appeal by the defendant A and the defendant C Federation, this case is a small case to which the Trial of Small Claims Act applies, and thus, the appeal may be filed with the Supreme Court only when the grounds prescribed in Article 3 of the Act exist.

The above Defendants’ ground of appeal does not fall under any of the above provisions, and thus cannot be a legitimate ground of appeal.

2. According to the records of the judgment on the appeal by Defendant B limited liability company, Defendant B limited liability company was served on May 4, 2020 and did not submit the appellate brief despite the lapse of the period for filing the appellate brief. The appellate brief submitted by Defendant B limited liability company is not indicated in the grounds for appeal. Thus, the appeal by Defendant B limited liability company should be dismissed in accordance with Article 429 of the Civil Procedure Act.

3. Therefore, all appeals are dismissed, and the costs of appeal are assessed against the losing party. It is so decided as per Disposition by the assent of all participating Justices on the bench.
