All appeals are dismissed.

Of the costs of appeal, the Plaintiff’s appeal is due to the Defendant’s appeal.

The grounds of appeal are examined.

1. As to the Plaintiff’s appeal, the lower court calculated the unpaid wage payable to the Plaintiff on the premise that the agreement was concluded between the Plaintiff and the Defendant on the payment of the comprehensive wage system effective between the Plaintiff and the Defendant.

The judgment below

Examining the reasoning in light of the relevant legal doctrine and the record, the lower court did not err by misapprehending the legal doctrine on the comprehensive wage system wage payment agreement, as alleged in the grounds of appeal.

2. As to the Defendant’s appeal, the Defendant did not state the grounds for appeal in the petition of appeal, and did not submit the grounds for appeal within the submission period of legitimate grounds for appeal.

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