This book focuses on the changes in the national territory of the country due to the application of the “straight archipelagic baselines” system under UNCLOS. It will likewise evaluate the effects of R.A. 9522 to our territorial integrity and sovereignty, national security and our economic development as a nation. It will analyze if our interest as an archipelagic nation is amply protected by this new baseline law and if we fulfilled our obligation incumbent upon us as a member of the family of nations under the Convention.
