Liberal democracy – defined as popular sovereignty plus individual autonomy and human rights. It is a form of democracy, which emphasizes and protects individual freedom. Certain rights are viewed as inalienable, meaning they are elemental to the individual and cannot be transferred or revoked. This is usually accomplished through constitutional or statutory declarations of and prohibition of interference with these rights. It is often used to describe western democratic political system such as Australia, United States etc. Constitution is termed as the basic law of the country, upon which all other laws are based. The Constitution of a country contains a set of rules and values to guide the actions of those who govern and those who are governed. It explains how the government should be organised and how it should operate and designate the roles and responsibilities of state institutions or branches. Constitution is very crucial for a liberal democratic country because it provides the form and format of government, which serves as the benchmark by which all laws must rise so as not to benefit unfairly one group of people over another and ever always the body of law that protects those precious and undeniable rights of the people which is the basic of liberalism. Constitutions normally limit governmental actions in two ways: through the goals to be pursued, and the actions to be taken for their attainment. A liberal democracy system is now favoured by most of the western countries, it contains these key features: citizen’s freedom and rights, a competitive party system, representative political system, and constitution.
