Atty Antonio Bautista's Basic Evidence features a topical discussion of the rules on Evidence. It is mainly an academic discussion of the subject. The discussion generally go into the spirit of the rules. The book discusses the wisdom, the pros and cons of a particular rule.
U.S. caselaws and American authorities like Wigmore, Lilly and Kirkpatrick are extensively quoted to shed light on the various topics. And while our rules on Evidence are based on common law, some discussions may not apply in our jurisdiction on all fours.
The book is recommended if you want to know about the rationale of our rules on Evidence. But if you are studying for the bar, I won't recommend this book.
