The citizens of Lumina will be in charge of the city. The citizens will vote on all laws, and will be able to propose and create new laws.
Once the Direct Democracy has been established, citizens will vote on laws and will be able to establish new ministries and government organisations.
Ministers will be elected by citizens using Single-Transferable-Vote (STV) to run the ministries that may be created in the legislation. The power of ministers will be limited by the legislation written by citizens.
This system reduces corruption, as ministers cannot be bribed to change legislation (as they do not have the power to do so, without majority citizen approval).
This system makes each government ministries independent and autonomous from one-another, and increases accountability of ministers to the public, as they are directly responsible for their own ministries, with only the citizens above to report to.
