Option 1: Central Book Store Official E-Book

3. The "Codals" Mentality

Filipino law students treat Cruz’s book like a Civil Code codal. They don’t want narrative fluff; they want the rule, the exception, and the case. A PDF allows for Ctrl+F (Find) searchability—instantly jumping to "Treaty vs. Executive Agreement" or "Persons of International Law."

6. Verdict: Should you use the Cruz PIL PDF?

| If you are… | Recommendation | |-------------|----------------| | A law student needing quick reference for an old bar topic | Useful only as a supplement, but verify with a recent source (UN website, ICJ judgments, or a 2020+ textbook). | | A bar reviewee | Acceptable for revisiting foundational concepts you already studied; do not rely on it for post-2005 developments. | | A practitioner | No – too outdated for actual legal work. Use Shaw, Crawford, or a current Philippine PIL text. | | Someone with no budget | Borrow a physical copy. Avoid pirated PDFs – they harm local legal publishing and may contain errors from bad scanning. |
