The legislative power of autonomy refers to a unique power to maintain the existence of the autonomous body, achieve its goals and realize the substantial local autonomy.
In the Article 117, Clause 1 is stated that the local autonomous body handles mainly the welfare of local residents, manages the properties and make regulations on the autonomy within the scope of laws and ordinances guaranteening the local autonomy systematically and approving the legislative power of local autonomy.
With the advent of the local autonomous system in 1995 resulting in the new era of the popularly-elected local autonomy, increasing interest of people in local autonomy and increase in demand for complex, various administration along with now environmental changes in the era of localization, the roles of the local city council in making laws have been highly emphasized.
The local city council has become keenly interested in making a new type of laws with variety in order to comply with the change of period.
However, since the popularly-elected local autonomy was created in 1995, it has created conflicts and tensions between the executive and the local city council requesting reconsideration by leaders of local government and the upper office based upon the reason that regulations proposed by the local city council are against the law or beyond its legal limit and it has stirred up grave problems in the lawmaking process at the local city council on the ground that regulations re-decided at the local city council was brought to the supreme court and were found guilty for violating the upper laws.
Consequently, without local variety and originality for the realization of autonomy lawmaking activities of the local city council were nothing but the fragmentary lawmaking process according to the mandatory laws and ordinances. Even they are dependant on proposals by leaders of local government rather than the ones by the city council in exercising the right to make laws without any detailed practical plans.
Therefore, this study focuses on analyzing of problems that current systems of autonomous laws have under the recognition that it is difficult to specify the scope of law-making process without improving the current laws and systems which limit rights to make laws among autonomous legislative power and devising plans for laws and systems to broaden the scope of rights to make laws to resolve problems.
In this way laws are autonomous ones guaranteed by democratic justice and constitution made by decision-making process of the city council as laws and regulations in accordance with the law and from the viewpoint of system security theory, the theory of hereditary rights-related independent legislation corresponds with the purpose of the constitution.
In this study it is concluded by presenting expansion of autonomy as a way to improve systematically in order to broaden the scope of lawmaking power, improvement of judicial review system for laws, stipulation of standards for work distribution, systematization of local autonomous body's participation process in legislation and efforts of local city council to strengthen lawmaking instead.
