The costs of appeal are assessed against the plaintiff.

1. On the first ground for appeal

The main text of Article 66 (1) of the State Public Officials Act that provides that state public officials shall not engage in collective activities, such as labor campaign, does not violate Article 37 (2) of the Constitution (see Constitutional Court Order 90Hun-Ba27, Apr. 28, 1992). Public officials do not seem to have any reason or reason to permit collective activities, such as labor campaign, unlike general public officials. According to the reasoning of the judgment below, the plaintiff appeared to have been leading in the Seoul Teachers' Training Society, the NAF promoters and the Preparatory Committee. The above act of the plaintiff constitutes a preparatory act for the formation of a labor union, which constitutes a labor campaign stipulated in the main sentence of Article 66 (1) of the State Public Officials Act, and therefore, the plaintiff's act constitutes a violation of the above provision of the Act, which provides that public officials who do not obey the above obligation of the above Article 75 (1) 1 of the State Public Officials Act shall always have the duty to maintain the quality of teachers and employees belonging to the school. According to the above provision of Article 75 (1).

The judgment of the court below is just and correct, and there is no ground for appeal.

2. On the second ground for appeal

In the process of examining the appeal after the disciplinary action in this case, even if the plaintiff submitted a letter of explanation that he would withdraw from the former school according to the announcement of the Minister of Education (the Minister of Education at that time) that the plaintiff reflects the past mistakes and would provide relief when he withdraws from the school, according to the reasoning of the judgment below, the plaintiff was admitted to the preceding school after the above disciplinary action was taken, and the plaintiff appeared in the late debate program of the Korean Broadcasting System and made a statement about the legitimacy of the preceding school. In the process of examining the appeal, the plaintiff did not have any consistency in making a statement about the withdrawal from the school in the process of examining the appeal at the general secretary's office, and it did not have any doubt as to whether the withdrawal from the school was due to the plaintiff's actual intention. Thus, the plaintiff's failure to receive relief in the process of examining the appeal does not reflect the fact that the plaintiff was admitted to the previous school, which is an illegal organization, and rather, it seems that the plaintiff was not prepared and submitted the above statement based on the intention to withdraw from the previous school.

Therefore, the appeal is dismissed and all costs of appeal are assessed against the losing party. It is so decided as per Disposition by the assent of all participating Justices on the bench.
