What is at the center of a representative democracy

At the center of a representative is an independent judiciary

Explanation:

The aim of a representative democracy is to provide a voice to every citizen by giving them the power to elect their representatives in a parliament.

In the parliament, these 'representatives' can project the voice of the people and ensure new laws and legislation is made to meet their needs.

At the heart of this is an Independent Judiciary.

The power of each elected individual is curtailed through a constitution which is upheld by an independent judiciary which is not influenced by any external factors.

This ensures fair play and rule of law.
