Since the GAPA is a fundamental law on administration and has the nature of a general law, it is necessary to hasten the reorganization of the laws in each administrative field from a systematic perspective in order to establish normative status and relationships with other laws. In other words, the purpose pursued by the GAPA cannot be realized only in terms of the GAPA, but can be got through synergy effects with other laws. So as to the GAPA must be improved accordingly in connection with the Administrative Appeals Act, Administrative Litigation Act, and National Compensation Act. The laws in each administrative field need to be reorganized in a way that embodies ‘participation’ and ‘cooperation’ as a paradigm shift in administrative law.
 In order to realize the rule of law on administration, specifying administrative law which serves as the standard for the exercise of public power is needed and important. Specifying administrative law is also necessary to ensure efficiency, adequacy, and predictability of public administration. This GAPA is not an administrative code, but a ‘fundamental law’ on administrative laws, and is the result of legislating only those matters on which consensus could be reached from existing administrative laws, administrative precedents, and theories among the basic norms related to administration.
 In the sense that the GAPA must be ‘Korean yet universal,’ the enactment of the GAPA represents the starting point of a long journey toward the ‘Administrative Code.’ Therefore, various legislative theories actively raised in the field of administrative law must be carefully reviewed on the spirit above.
 This study reviewed the main contents of the “Geneal Act on Public Administration” (hereafter GAPA) in terms of legislative theory following: specifying general principles of administrative law (Articles 8 to 13 of the Act), subordinate clauses of administrative disposions(Article 17), revocation of illegal or unjust dispositions and withdrawal of legitimate dispositions(Articles 18 and 19), automatic dispositions(Articles 20), limitation period for sanctions (Article 23), standards for deemed authorization or permission(Articles 24 to 26 ), general provisions on contracts under public law(Article 27), regulations on the effectiveness of reports requiring acceptance(Article 34), general institutionalization of objections to dispositions(Article 36), re-examination of dispositions(Article 37).
