Constitutional Amendment Processes Across Democracies

Quick fact

In the United States, a constitutional amendment requires a two-thirds majority in both houses of Congress and ratification by three-fourths of the states—one of the most difficult processes in the world. In contrast, New Zealand can amend its constitution through a simple majority vote in Parliament, making it one of the easiest.
