The Philippines Is a Legal Hybrid: Civil Law Meets Common Law
By Giancarlo Angulo
Murky rules bother me more than bad rules. A bad rule you can plan around. A murky one makes every decision suspect and every outcome a coin flip. I’d like to understand why our rules are so often unclear, and what we could do about it. It starts with a history lesson.
TLDR
- The Philippines is a mixed jurisdiction: civil law (from Spain) governs most private life, and common law (from the US) shapes how our courts, constitution and procedures work.
- “Constitutional law” is not the other half of this pair. It is a field of law. The two traditions are civil law and common law. (Our Constitution itself is mostly American in style.)
- Two more layers sit on top: Islamic personal law for Filipino Muslims and customary law for indigenous peoples.
- Other countries are hybrids too: Scotland, South Africa, Quebec, Louisiana and more.
- In part 2, I’ll argue that this mix makes it harder to know the rules of the game.
Two ways of building a legal system
Civil law: start from the code
Civil law traces back to Roman law. The emperor Justinian had Roman law compiled in the 6th century (the Corpus Juris Civilis), and European universities, starting with Bologna in the 11th–12th centuries, revived it. The big milestone came with codification: Napoleon’s Civil Code of 1804 and, later, the German code (BGB) of 1900. These codes became models for much of continental Europe, Latin America and Spanish and Portuguese colonies, including the Philippines.
The idea: lawmakers write comprehensive codes in advance. The judge’s job is to apply the code to the facts.
Common law: start from the case
Common law grew in England after the Norman Conquest of 1066. Over the next century or so, royal judges, notably under Henry II (1154–1189), traveled the country and settled disputes using a shared body of rulings. The law became “common” to the whole realm. Judges followed earlier decisions, which turned into precedent (stare decisis, “stand by what has been decided”). The system spread through the British Empire and the United States.
The idea: law grows case by case. Statutes exist, but court decisions fill in and shape the rules.
The differences, in short
| Civil law | Common law | |
|---|---|---|
| Main source | Codes and statutes | Court decisions plus statutes |
| Judge’s role | Applies the code; case law is persuasive | Interprets and, in effect, develops the law; precedent binds |
| Court procedure | More judge-led (inquisitorial tendency) | More lawyer-led (adversarial); juries in many places |
| Legal writing | Systematic, doctrinal; scholars matter | Case reasoning; judges’ opinions matter |
| Typical countries | France, Germany, Spain, Latin America, Japan | England, US, Canada (outside Quebec), Australia, India |
In practice the two have moved toward each other: civil-law countries use court rulings more, and common-law countries pass more statutes and codes. The table shows the starting points, not strict walls.
How the Philippines ended up with both
Spanish period (1565–1898). Spanish law applied here, including the Siete Partidas and later colonial codes. The Spanish Civil Code was extended to the Philippines in 1889. A Penal Code (1887) and a Code of Commerce (1888) had been extended before it.
American period (1898–1946). After the Treaty of Paris, the US brought its own legal institutions: a constitution-style government under the Philippine Bill of 1902 and the Jones Law of 1916, a Supreme Court (Act No. 136, 1901), American-style rules of procedure and court practice, and English as the language of law. The 1935 Constitution, drafted by a Filipino convention authorized by the Tydings–McDuffie Act (1934) and approved by the US President, carried over the Bill of Rights and judicial review: the American idea that courts can strike down laws that violate the constitution.
Independence and our own codes. After 1946 we kept both layers and wrote our own versions:
- The Civil Code of the Philippines (Republic Act 386, enacted 1949, in force 1950) is built on the Spanish civil-law tradition, with some American ideas added.
- The Revised Penal Code (Act 3815, enacted 1930, in force January 1, 1932) is based on the Spanish penal code.
- The Family Code (Executive Order 209, 1987) updated family law while staying within the civil-law tradition.
The result: a split by subject
Roughly:
| Area | Mostly from | Examples |
|---|---|---|
| Persons, family, property, obligations and contracts, succession | Civil law (Spain) | Civil Code, Family Code |
| Crimes | Civil law (Spain) | Revised Penal Code |
| Constitutional law, bill of rights, judicial review | Common law / US | 1987 Constitution |
| Court procedure, evidence | Common law / US | Rules of Court |
| Corporations, securities, much of commercial regulation | US-influenced | Revised Corporation Code (RA 11232, 2019) |
And where precedent is concerned, Article 8 of the Civil Code says: “Judicial decisions applying or interpreting the laws or the Constitution shall form a part of the legal system of the Philippines.” In other words, Supreme Court rulings carry real weight, and courts are expected to follow them under the doctrine of stare decisis. The code-based civil-law system quietly adopted the common-law habit of precedent. That is the hybrid at work.
More layers than two
- Islamic personal law. The Code of Muslim Personal Laws (Presidential Decree 1083, 1977) governs marriage, divorce, inheritance and related matters for Filipino Muslims, applied by Shari’a courts. The Bangsamoro Organic Law (RA 11054, 2018) provides for Shari’a within the Bangsamoro region (BARMM), applying to Muslims.
- Customary law of indigenous peoples. The Indigenous Peoples’ Rights Act (RA 8371, 1997) recognizes customary law and ancestral domain.
- Barangay justice. The Katarungang Pambarangay, now part of the Local Government Code of 1991, requires many local disputes to go through barangay conciliation before reaching court.
- International law. The 1987 Constitution (Art. II, Sec. 2) says the Philippines “adopts the generally accepted principles of international law as part of the law of the land.”
We are not the only hybrid
Legal scholars call these mixed jurisdictions. Well-known examples:
- Scotland: civil-law roots with common-law development.
- South Africa: Roman-Dutch civil law plus English common law.
- Quebec (Canada): civil law for private matters, common law for public and criminal law.
- Louisiana (US): a civil-law tradition from France and Spain inside a common-law country.
- Puerto Rico: like us, a former Spanish colony later under US rule.
- Israel, Sri Lanka, Mauritius and Malta: other mixes of civil law, common law and local or religious traditions.
- Malaysia and Singapore: common-law systems that also recognize Islamic family law for Muslims.
The Philippines and Puerto Rico share a similar story: Spanish codes first, then American courts and constitutionalism.
Why this matters (and what’s next)
Having two traditions under one roof can be a strength: the Civil Code gives us stable, written rules for family and property, and the American-style courts give us judicial review and a bill of rights with teeth. But it also means a judge or lawyer can reach for the code in one case and for precedent in another.
In part 2, I’ll look at whether that mix makes our laws harder to predict, using a major Supreme Court case as an example, and I’ll be clear about where my argument may be wrong.
Corrections welcome. I’m a technologist, not a lawyer. If you spot an error, please comment.
