constitutional prohibition against inequality, that every man, woman and child should be affected alike by a statute. Equality of operation of statutes does not mean indiscriminate operation on persons merely as such, but on persons according to the circumstances surrounding them. It guarantees equality, not identity of rights. The Constitution does not require that things which are different in fact be treated in law as though they were the same. The equal protection clause does not forbid discrimination as to things that are different. It does not prohibit legislation which is limited either in the object to which it is directed or by the territory within which it is to operate. The equal protection of the laws clause of the Constitution allows classification. Classification in law, as in the other departments of knowledge or practice, is the grouping of things in speculation or practice because they agree with one another in certain particulars. A law is not invalid because of simple inequality. The very idea of classification is that of inequality, so that it goes without saying that the mere fact of inequality in no manner determines the matter of constitutionality. All that is required of a valid classification is that it be reasonable, which means that the classification should be based on substantial distinctions which make for real differences; that it must be germane to the purpose of the law; that it must not be limited to existing conditions only; and that it must apply equally to each member of the class. This Court has held that the standard is satisfied if the classification or distinction is based on a reasonable foundation or rational basis and is not palpably arbitrary. (Emphasis supplied) Measured against the foregoing jurisprudential yardstick, we find that R.A. 9262 is based on a valid classification as shall hereinafter be discussed and, as such, did not violate the equal protection clause by favoring women over men as victims of violence and abuse to whom the State extends its protection. I. R.A. 9262 rests on substantial distinctions. The unequal power relationship between women and men; the fact that women are more likely than men to be victims of violence; and the widespread gender bias and prejudice against women all make for real differences justifying the classification under the law. As Justice McIntyre succinctly states, "the accommodation of differences ... is the essence of true equality."70 A. Unequal power relationship between men and women According to the Philippine Commission on Women (the National Machinery for Gender Equality and Women's Empowerment), violence against women (VAW) is deemed to be closely linked with the unequal power relationship between women and men otherwise known as "gender-based violence". Societal norms and traditions dictate people to think men are the leaders, pursuers, providers, and take on dominant roles in society while women are nurturers, men's companions and supporters, and take on subordinate roles in society. This perception leads to men gaining more power over women. With power comes the need to control to retain that power. And VAW is a form of men's expression of controlling women to retain power.71 The United Nations, which has long recognized VAW as a human rights issue, passed its Resolution 48/104 on the Declaration on Elimination of Violence Against Women on December 20, 1993 stating that "violence against women is a manifestation of historically unequal power relations between men and women, which have led to domination over and discrimination against women by men and to the prevention of the full advancement of women, and that violence against women is one of the crucial social mechanisms by which women are forced into subordinate positions, compared with men."72 Then Chief Justice Reynato S. Puno traced the historical and social context of gender-based violence and developments in advocacies to eradicate VAW, in his remarks delivered during the
