2. Determination

A. 1) In order for an administrative disposition defective in the relevant legal doctrine to become null and void automatically, such defect must be objectively obvious as it violates the important part of the relevant law. In determining whether the defect is significant and apparent, the purpose, meaning, function, etc. of the relevant law should be considered from a teleological perspective and reasonable consideration of the specificity of the specific case itself at the same time (see, e.g., Supreme Court en banc Decision 2010Du10907, Feb. 16, 2012). Meanwhile, in cases where an administrative agency takes an administrative disposition by applying any provision of a law to a certain legal relation or fact, the legal doctrine that the provision of the relevant law cannot be applied to such legal relation or fact is not clearly revealed.
