Sources of Law
The main sources of Philippine law are:
the Constitution - the fundamental and supreme law of the land
statutes - including Acts of Congress, municipal charters, municipal legislation, court
rules, administrative rules and orders, legislative rules and presidential issuances.
treaties and conventions - these have the same force of authority as statutes.
judicial decisions - Art 8 of the Civil Code provides that ‘judicial decisions applying to or
interpreting the laws or the Constitution shall form a part of the legal system of the
Philippines’. Only decisions of its Supreme Court establish jurisprudence and are binding
on all other courts.
To some extent, customary law also forms part of the Filipino legal system. Art 6, para 2 of the
Constitution provides that ‘the State shall recognise, respect, and protect the rights of indigenous
cultural communities to preserve and develop their cultures, traditions and institutions’.
The primary sources of Muslim law / Shariah are the Quran, Sunnaqh, Ijma and Qiyas.
