2. Determination

A. 1) In order for an administrative disposition defective in the relevant legal principles to become null and void automatically, such defect must be objectively obvious as it violates an important part of the relevant law. In determining whether a defect is significant and apparent, the purpose, meaning, function, etc. of the relevant law should be examined from a teleological perspective, as well as reasonable consideration of the specificity of the specific case itself (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 a certain provision of a law to a certain legal relation or factual relationship, if there is room for dispute over the interpretation of the law because the legal principle that the provision of the law cannot be applied to such legal relation or factual relations is not clearly revealed, it shall also be interpreted by erroneous interpretation of the administrative disposition.
