2. Determination ex officio as to the legitimacy of the instant lawsuit

A. Relevant legal principles 1) A lawsuit for confirmation may be brought only when the judgment becomes effective and appropriate to eliminate the Plaintiff’s legal status’s risks or unstableness in the case of disputes or conflicts of interest regarding the existence of present rights or legal relations. Thus, a mere assertion of factual relations cannot be a subject of confirmation. Although there are facts that constitute the legal requirements for creating current legal relations among the allegations on factual relations, it is nothing more than one legal fact (see, e.g., Supreme Court Decision 2008Da35098, Oct. 23, 2008). 2) A lawsuit for confirmation is not a subject of confirmation only between the parties, but it is not a subject of confirmation as to the legal relationship or the relationship between a party and a third party.
