The new Philippine Constitution is one of the essential sources of rights of the Filipino people. The study aimed to determine the status of the new Philippine Constitution in the application of natural rights of man on the Social Contract Theory of John Locke as a basis for enhancement. The study utilized the historical method of research using expository technique based on the idea of John Locke. Section 1 of the Article 3 of the 1987 Philippine Constitution provides that no person shall be deprived of life, liberty or property without due process of law, nor shall any person be denied the equal protection of the laws. This research is significant since it deals with the individual rights of man specifically the natural rights that are protected by the government otherwise the people can have the right to revolt. The idea of the Philippine Constitution on the natural rights of man insignificantly differs from the Social Contract Theory of John Locke. John Locke’s idea particularly on the foundation of the Declaration of Independence could be realized by the Filipinos with the help of the legislatures and experts on this field.
