A. The defendant's assertion

The plaintiff is a foreigner and constitutes a person who acquired the nationality of the Republic of Korea in a astronomical manner through a special report on the acquisition of nationality for a mother-born under the supplementary provision of the Addenda to the Nationality Act. Article 3 of the Addenda to the current Nationality Act provides that "The amended provisions of Article 10 apply to a person who does not waive the foreign nationality because he falls under the proviso of Article 10 (2) before this Act enters into force," and therefore, the plaintiff is merely a person who has renounced the foreign nationality under Article 10 of the Nationality Act or a person who is subject to a non-exercise of the foreign nationality under Article 11-2 of the Nationality Act, and thus does not constitute a person who can report the renunciation of nationality as a part of the fulfillment of the obligation to nationality selection, since he is not a "person

B. Determination

1) Whether the Plaintiff constitutes a person who acquired nationality of the Republic of Korea in a astronomical manner

2) Article 2(1)1 of the Nationality Act amended by Act No. 5431 of Dec. 13, 1997 to eliminate the unconstitutionality of the above provision of the former Nationality Act (amended by Act No. 5431 of Dec. 13, 1997, Article 2(1)1 of the former Nationality Act (amended by Act No. 5431 of Dec. 13, 1997) provides that the person whose father or mother is a national of the Republic of Korea at the time of birth shall acquire the nationality of the Republic of Korea at the same time as the birth of the Republic of Korea and adopted the principle of parent support support support. In light of the newly established provisions of the latter part of the instant case, it is reasonable to view that the person who acquired the nationality of the Republic of Korea as a special person for mother support under the Addenda of the instant case, who actually acquired the nationality of the Republic of Korea at the same time as the birth of a foreign country and at the same time under the same time as the nationality of the Republic of Korea.

Therefore, the Plaintiff, not later than a person who acquired the nationality of the Republic of Korea in the future, should be deemed to fall under “a person who has both the nationality of the Republic of Korea and that of a foreign country under this Act” or “a person with multiple nationalities” under Article 11-2(1) of the Nationality Act.

A) Relevant legal principles

In the amendment of Acts and subordinate statutes, the trust of the parties to the existence of the former Act and subordinate statutes is reasonable and reasonable, and if the public interest purpose to achieve new Acts and subordinate statutes is not justified due to extreme damage to the parties involved, the legislators shall take appropriate measures to protect the parties' trust by establishing transitional regulations, etc. It is not permissible to implement or apply the new Acts and subordinate statutes without such appropriate measures. This is because, on the one hand, if a citizen has formed a certain legal status or living relationship with a specific act corresponding to the relevant Acts and subordinate statutes, based on reasonable and justifiable trust that a certain statute will continue in the future, and if the State does not protect it at all, the people's trust in the legal order will collapse and have a big impact on the current act, and thus it violates the principle of protection of trust derived from the principle of the rule of law, which is the basic principle of the Constitution. To determine whether such principle of protection of trust is violated, on the other hand, the protection value of infringed interests, the degree of infringement, degree of damage caused, and new methods of infringement on trust, etc.
