According to Art. 14 of Local Government Act, Special municipalities, counties/cities, and townships/cities are local self-governing bodies, and shall carry out self-government matters in accordance with this Act as well as the matters commissioned by higher government agencies. And Special municipalities, counties/cities, and townships/cities may, in accordance with law or upon authorization from higher government levels, formulate self-government ordinances and regulations. Self-government ordinances and regulations passed by the local legislative body and promulgated by the administrative body shall be called self-government ordinances; those formulated and promulgated or announced by the local administrative body shall be called self-government regulations. But how to define the self-government matters is an issue.
