Constitutional changes refer to modifications made to a country's constitution, which is the fundamental legal document outlining the structure of government and the rights of citizens. These changes can occur through various processes, such as amendments, new legislation, or judicial interpretations. In many democracies, amendments require approval from a certain percentage of lawmakers or a public referendum. In the United States, for example, the process for amending the Constitution is outlined in Article V. This process ensures that changes reflect the will of the people and maintain the integrity of the U.S. Constitution. Constitutional changes can address social issues, expand rights, or adapt to new circumstances, ensuring the document remains relevant over time.
