Constitutionalism refers to the adherence to a constitution. It is the belief and practice that government power should be exercised within the framework of a constitution, which outlines the structure of government, the distribution of power, and the rights of the citizens. Constitutionalism ensures that the government does not act outside the limits of the law, and that the rights of the citizens are protected. It involves respecting the rule of law, separation of powers, checks and balances, and the protection of individual rights and freedoms as enshrined in the constitution. Constitutionalism is an important aspect of democracy and good governance.
