1. The plaintiff's appeal is dismissed.

2. The costs of appeal shall be borne by the Plaintiff, including the part arising from the supplementary participation.

The court's explanation of this case is identical to the reasoning of the judgment of the court of first instance, and thus, citing this case in accordance with Article 8 (2) of the Administrative Litigation Act and the main sentence of Article 420 of the Civil Procedure Act.

(A) The grounds for the plaintiff's assertion in the trial are not significantly different from the allegations in the trial of the first instance. Even if the evidence submitted in the trial of the first instance and the trial of the first instance are examined, the strike in this case constitutes an unlawful act of dispute, and the plaintiff's planning, leading, or inducing the strike in this case to the position of the chairman of the Central Dispute Countermeasures Committee and the chairman of the Local Headquarters constitutes the grounds for disciplinary action as stipulated in Article 52 (1) through (5) of the Intervenor's personnel regulations, and the decision of the first instance that deemed appropriate for the plaintiff's disciplinary action of removal in this case against the plaintiff is justifiable. Accordingly, the plaintiff's claim is dismissed as it is reasonable, and the judgment of the first instance is dismissed as the plaintiff's appeal is without merit. It is so decided as per Disposition by the assent of all participating Justices.
