The reasoning of the judgment of this court is identical to the reasoning of the judgment of the court of first instance, and such reasoning is cited in accordance with the main sentence of Article 420

[In light of the evidence duly adopted and examined by the court of first instance, the fact finding and determination by the court of first instance is justifiable, and there is no error as alleged by the plaintiff and the defendant as the grounds for appeal (and the grounds for appeal). Each description of evidence Nos. 11 and 12 (including the serial number) submitted by the defendant in the trial is insufficient to reverse the judgment of the court of first instance as to the establishment of tort]. The plaintiff's appeal and the defendant's incidental appeal are dismissed as they are all without merit
