The judgment of the court below is reversed.

Defendants shall be punished by a fine of KRW 500,000.

The Defendants did not pay a fine.

1. Summary of grounds for appeal;

A. Although the Defendants, by mistake of facts or misapprehension of legal principles, installed a banner as stated in the facts charged in the instant case, it is intended to guarantee the right of occupants to know about the construction project to expand the apartment parking lot, so there is no intention to commit defamation against the Defendants.

In addition, since the contents of the above banner are true facts and are related to the public interest of apartment occupants, it is justified.

B. Each sentence of the lower court on the grounds of unreasonable sentencing (one million won of a fine) is too unreasonable.
