Independence of judiciary is determined to a great extent by the mode of appointment of its members. They may appointed by the people through the elections or indirectly by the members of the legislature for a fixed term. They may also be appointed by the head of state through nomination.
In modern times we have indirect democracy, under this system the people elect their representatives and give them the authority to make the law and implement them. Actually in democracy sovereignty belongs to people but under normal circumstances it becomes difficult for the people to legislate directly. So sometimes the people make the laws directly.
Sovereignty is one of the most essential and unique features of the state. It is the ultimate and supreme law and policy making authority of the state. It is the soul of state. It is that element of the state, whit distinguishes the state from all, other associations.
