The costs of appeal between the Plaintiff and the Defendant are assessed against Defendant B, the Plaintiff and the Defendant.

Since this case is a small case, an appeal may be filed only when there is a ground set forth in the subparagraphs of Article 3 of the Trial of Small Claims Act, which does not fall under any of the grounds for appeal.

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.
