EXPLANATORY NOTE 
Article II, Section 14 of the Constitution declares: 
“The State recognizes the role of women in nation-building, 
and shall ensure the fundamental equality before the law of women 
and men.” 
Consistent with the constitutional mandate, in the Family Code, the terms 
“adu/fey”(on the part of the wife) and “concubinage” (on the part of the husband) 
has been replaced with “sexual infidelity” (on the part of either spouses) as one 
of the grounds for legal separation (Article 55 of EO 209, as amended). 
However, long after the passage of the Family Code in 1987, the Revised 
Penal Code has yet to remove the distinction between adultery (Art. 333) and 
concubinage (Art. 334) as felonies, thus perpetuating the disadvantaged position 
of the wife, who is penalized with a heavier penalty than the husband, and whose 
single act of iiifidelity consummates the offense. This is different in the case of 
the husband, whose marital indiscretion is not treated as a felony unless 
attended by the circumstances enumerated in Article 334. 
This disparate treatment of wives and husbands is recognized in the 
Philippine jurisprudence: 
“To our legislators adultery is not a violation of the laws 
relating to marriage. It is a violation of those laws only when it is 
committed by a woman. The husband can break those laws without 
committing adultery. She, in other words, is, in reality, the only 
person capable of committing the crime under the law of the 
Philippines Islands .... (US. vs. Topino & Guzman, dissenting 
opinion of Moreland, J., 35 Phil. 901, 916).” 
The bill seeks to end the discriminatory treatment of wives-and 
effectively, to harmonize the Revised Penal Code with the present provisions of 
the Family Code-by 
doing away with the distinction between adultery and 
concubinage, and instead criminalizing any and all acts of sexual infidelity, 


regardless of which spouse commits it. The proposed amendment also 
abrogates the traditional essence of adultery, that is, the danger introducing 
spurious heirs into the family. Sexual infidelity becomes now, as it should be, a 
violation of the laws relating to marriage. 
In view of preserving the fundamental equality of women and men as 
guaranteed by the Constitution, the passage of this bill is earnestly sought.
