Today, most countries in the world have a Constitution. While all democratic countries are likely to have a Constitution, it is not necessary that all countries that have a Constitution are democratic. There can be several purposes for drafting a constitution, they are:
- To provide a set of basic rules that allow for minimal coordination amongst members of society.
- To specify who has the power to make decisions in a society. It decides how the government will be constituted.
- To set some limits on what a government can impose on its citizens. These limits are fundamental in the sense that government may never trespass on them.
- To enable the government to fulfil the aspirations of a society and create conditions for a just society.
Therefore, it can be understood that the constitution allows coordination and assurance. On the other hand, it can limit the powers of the government.
