All appeals are dismissed.

The grounds of appeal are examined.

A dance institute, which is a kind of amusement facilities under the Building Act, refers to a facility where dancing is taught for a fee, but exceptionally, in cases where it is deemed that there is no risk of undermining good morals in view of the subject and contents of lessons, the details and purport of the relevant Acts and subordinate statutes concerning the establishment and operation of teaching facilities, and the subject of regulation under Acts and subordinate statutes related to public morals, it does not constitute a dance institute which is a kind of amusement facilities under

A private teaching institute which meets the registration requirements of a private teaching institute for school curriculum under the Act on the Establishment and Operation of Private Teaching Institutes and Extracurricular Lessons (hereinafter referred to as the "Private Institutes Act") and aims to teach dances or dances sports contained in the school curriculum under the Elementary and Secondary Education Act, is likely to impair good morals.

It is difficult to see it.

Therefore, if the requirements for registration of a private teaching institute under the Private Institutes Act are met, it does not constitute a dance institute which is a kind of amusement facilities under the Building Act (see, e.g., Supreme Court Decision 2013Du15774, Jun. 28, 2018). According to the records, the Defendant A filed an administrative suit with the head of the competent district office of education to revoke the registration of a private teaching institute that meets the requirements for a private teaching institute under the Private Institutes Act, but did not constitute a private teaching institute that is subject to registration under the Private Institutes Act; Defendant A filed an administrative suit to revoke the registration of a private teaching institute; Defendant A filed an administrative suit to the effect that the private teaching institute operated by the Defendant A does not constitute a dance institute that is a kind of amusement facilities under the Building Act, which is an amusement facility under the Private Institutes Act (see Supreme Court Decision 2013Du15774, Jun. 28, 2018).

Examining the above facts in light of the legal principles as seen earlier, the dance institute operated by Defendant A is in the school curriculum under the Elementary and Secondary Education Act.
