The judgment of the court below is reversed, and the case is remanded to the Seoul Central District Court Panel Division.

The grounds of appeal are examined.

1. According to Article 12(1) of the Assembly and Demonstration Act and Article 12(2) of the Enforcement Decree of the Assembly and Demonstration Act, the head of the competent police authority may prohibit an assembly or demonstration on the major roads of major cities prescribed by Presidential Decree, if deemed necessary to ensure traffic flow, or restrict the assembly or demonstration with conditions attached thereto for maintaining traffic order. In cases of restricting the assembly or demonstration with conditions attached to maintaining traffic order, the head of the competent police authority shall notify the organizer in writing specifying the relevant conditions.

The notification of the conditions for maintaining traffic order under Article 12(1) of the Assembly and Demonstration Act is different from the notification of the prohibition and restriction of an assembly or demonstration under Article 8 of the Assembly and Demonstration Act.

It should be viewed valid as a notification of legitimate transport conditions.
