Twenty-five years after its ratification, the 1987 Constitution has survived serious attempts to change it during the presidencies of Fidel Ramos, Joseph Estrada, and Gloria Macapagal Arroyo. What were the reasons for the attempts and why did they fail? For persons and organizations with valid reasons to explore Charter Change, what are the available options? What is a systematic way to explore and pursue it? These are some of the questions this book examines and answers.
