Constitutional reform refers to changes made to a country's constitution, which is essentially its governing document. This can involve altering or amending certain aspects of the existing constitution, such as changing the structure of government, the powers of different branches, or the rights and freedoms of citizens. The purpose of constitutional reform can vary depending on the specific changes being made - it could be to increase democracy, improve human rights protections, or address issues related to regional autonomy or federalism. Ultimately, the goal is to make the country's governing document more reflective of its current needs and values while maintaining stability and continuity in governance.
