The powers and functions of the district organizations and the method for their formation shall be prescribed by __________.

The powers and functions of district organizations, as well as the methods for their formation, are established by law in Hong Kong. This is consistent with the rule of law principle embedded in the Basic Law, which serves as the constitutional framework for the Hong Kong Special Administrative Region.

By prescribing the framework through law, it ensures that there is a clear legal basis for the operation and governance of district organizations, thus reinforcing accountability and transparency. Laws can provide detailed regulations that cater to the unique needs and conditions of different districts, allowing for proper alignment with the overall administrative structure of Hong Kong.

While international agreements play a significant role in the broader context of governance and relations, they do not directly govern the specifics of local district organizations. The Chief Executive has significant authority in governing but the creation and specific stipulations concerning district organizations are not solely at their discretion; they must also rely on legislative enactments. The Central People's Government has overarching authority over the region but typically defers to local laws for local administrative matters. Thus, the decision to empower district organizations and define their operational parameters is grounded in law.
