The defendant's grounds for appeal citing the judgment of the court of first instance are not significantly different from the argument in the court of first instance, except for adding the following arguments to this court, and even if each evidence submitted to the court of first instance is presented to this court, the fact-finding and judgment of the court of first instance are justified.

Therefore, the court's explanation on this case is consistent with the reasoning of the judgment of the court of first instance, except for the addition of the following '2. additional determination' as to the assertion added by the defendant to this court, and thus, it is consistent with the main sentence of Article 420 of the Civil Procedure Act.
