In the first instance trial, the Plaintiff filed a claim for confirmation of invalidity of each disciplinary measure with Defendant B’s regional headquarters (hereinafter “Defendant B’s regional headquarters”) as the primary Defendant and Defendant C Trade Union (hereinafter “Defendant C Trade Union”) as the primary Defendant.

The first instance court rejected the plaintiff's lawsuit against the primary defendant, and accepted the claim against the conjunctive defendant.

On this issue, only the conjunctive defendant appealed.

Where one of the main co-litigants and the conjunctive co-litigants files an appeal in a subjective preliminary co-litigation, the part of the claim against other co-litigants shall be prevented, and it shall be subject to adjudication in the appellate court (see, e.g., Supreme Court Decision 2006Du17765, Mar. 27, 2008). In such a case, the subject of adjudication on an appeal shall be determined by considering the necessity of the unity of the conclusion between the main co-litigants and their other parties (see, e.g., Supreme Court Decision 2009Da4355, Feb. 24, 201). Thus, the scope of adjudication in this court shall be determined by the appeal of the conjunctive defendant, and the part of the claim against the primary defendant was transferred to the appellate court.
