If Game Rating Board tries to interpret the paragraph 4 of Article 22 of Act on the Promotion of the Game Industry as the meaning that it can revoke it’s rating of a game when the rated game falls under the category of rating rejection owing to Ordinance’s revision after the rating, the interpretation could violate constitutionalism and protection of trust. According to the paragraph 2 and 4 of Article 22 of The Act, The Board may reject a rating application filed by an entity that has requested a rating without legitimate authority or that is using other illegal methods and shall, without delay, revoke its rating when it determines or discovers that a rated game falls under the category of rating rejection. Administrative court ruled that the interpretation of a law regarding revocation of a beneficial administrative disposition should be limited in the original meaning of the law; it is desirable that the Board’s the Interpretation Criteria of Ordinance relating to the revocation of a game rating could be reconsidered in the viewpoint of constitutionalism and protection of trust.
