Since the formation of local legislative bodies in the Philippines, Philippine legal codes have been enacted by the
legislature, in the exercise of its powers of legislation. Since 1946, the laws passed by the Congress, including legal codes, have been titled
Republic Acts. While Philippine legal codes are, strictly speaking, also Republic Acts, they may be differentiated in that the former represents a more comprehensive effort in embodying all aspects of a general area of law into just one legislative act. In contrast, Republic Acts are generally less expansive and more specific in scope. Thus, while the
Civil Code seeks to govern all aspects of
private law in the Philippines, a Republic Act such as Republic Act No. 9048 would concern itself with a more limited field, as in that case, the correction of entries in the
civil registry. Still, the amendment of Philippine legal codes is accomplished through the passage of Republic Acts. Republic Acts have also been utilized to enact legislation on areas where the legal codes have proven insufficient. For example, while the possession of narcotics had been penalized under the 1930s
Revised Penal Code, the wider attention drawn to illegal drugs in the 1960s and the 1970s led to new legislation increasing the penalties for possession and
trafficking of narcotics. Instead of enacting amendments to the Revised Penal Code, Congress chose instead to enact a special law, the Dangerous Drugs Act of 1972. ==List==
