The defendant's appeal is dismissed.

1. Summary of grounds for appeal;

A. The defendant's act constitutes a legitimate defense, since the victim, first of all, was a victim of a political party's defense, committed an attack on the defendant's chest while being sealed by the defendant, and the defendant was only sealed to the defendant to avoid defending the defendant.

B. The victim of a political party’s act, first of all, pointed out the fluorous behavior of young people by the Defendant, and the victim continued to be fluorially, and had been able to escape tobacco before the Defendant. In such a situation, the act, such as the Defendant’s written facts charged, constitutes a justifiable act in light of the sound social norms of the victim, in light of the victim’s non-fluorial behavior.
