The defendant's appeal is dismissed.

1. Summary of grounds for appeal;

A. The Defendant, as stated in the facts charged, did not inflict an injury on the victim.

Even if the defendant inflicted an injury on the victim,

Even if this is to defend the attack of the victim, the defendant's act constitutes legitimate defense.

B. The sentence of the lower court’s improper sentencing (an amount of KRW 500,000) is too unreasonable.

2. Determination

A. The Defendant alleged the same purport in the lower court’s determination as to the assertion of mistake of facts, and the lower court rejected the above assertion in detail by stating in the column of “determination on the assertion of the Defendant and his defense counsel.” In light of the records, the lower court’s determination is just and acceptable, and there is an error of law by misunderstanding of facts, as alleged by the Defendant.

Therefore, the defendant's mistake of facts is without merit.

B. Determination 1 on the unfair argument of sentencing is based on statutory penalty, and the discretionary determination is made within a reasonable and appropriate scope, taking into account the factors constituting the conditions for sentencing under Article 51 of the Criminal Act, based on the statutory penalty. In our criminal litigation law that takes the principle of court-oriented trials and the principle of directness, there is a unique area for determination of sentencing under Article 1.

In addition, in light of these circumstances and the ex post facto in-depth nature of the appellate court, it is reasonable to respect the sentencing in the event that there is no change in the conditions of sentencing compared with the first instance court, and the sentencing of the first instance does not deviate from the reasonable scope of the discretion. Although the sentence of the first instance falls within the reasonable scope of the discretion, it is desirable to reverse the judgment of the first instance on the sole ground that the sentence of the first instance falls within the scope of the discretion of the appellate court and to refrain from imposing a sentence that does not differ from the first instance court (see, e.g., Supreme Court Decision 2015Do3260, Jul. 23, 2015).
