Meanwhile, the term "illegal act of the spouse" as defined in Article 840 subparag. 1 of the Civil Act as a cause for judicial divorce as defined in Article 840 subparag. 1 of the Civil Act includes a broad concept that includes adultery, but does not reach a common sense, all unlawful acts that are not faithful to the husband's emotional duty, and the issue of whether the act was an unlawful act shall be determined by considering the degree and circumstances depending on the specific case (see, e.g., Supreme Court Decision 87Meu5, May 26, 1987).

The plaintiff is due to the defendant's act.
