conception." This conclusion is objective, consistent with the factual evidence, and
independent of any specific ethical, moral, political, or religious view of human life or of
human embryos.164
Conclusion: The Moment of Conception is Reckoned from
Fertilization
In all, whether it be taken from a plain meaning, or understood under medical parlance, and
more importantly, following the intention of the Framers of the Constitution, the undeniable
conclusion is that a zygote is a human organism and that the life of a new human being
commences at a scientifically well-defined moment of conception, that is, upon fertilization.
For the above reasons, the Court cannot subscribe to the theory advocated by Hon. Lagman
that life begins at implantation.165 According to him, "fertilization and conception are two
distinct and successive stages in the reproductive process. They are not identical and
synonymous."166 Citing a letter of the WHO, he wrote that "medical authorities confirm that
the implantation of the fertilized ovum is the commencement of conception and it is only
after implantation that pregnancy can be medically detected."167
This theory of implantation as the beginning of life is devoid of any legal or scientific mooring.
It does not pertain to the beginning of life but to the viability of the fetus. The fertilized
ovum/zygote is not an inanimate object - it is a living human being complete with DNA and
46 chromosomes.168 Implantation has been conceptualized only for convenience by those
who had population control in mind. To adopt it would constitute textual infidelity not only to
the RH Law but also to the Constitution.
Not surprisingly, even the OSG does not support this position.
If such theory would be accepted, it would unnervingly legitimize the utilization of any drug
or device that would prevent the implantation of the fetus at the uterine wall. It would be
provocative and further aggravate religious-based divisiveness.
It would legally permit what the Constitution proscribes - abortion and abortifacients.
The RH Law and Abortion
The clear and unequivocal intent of the Framers of the 1987 Constitution in protecting the
life of the unborn from conception was to prevent the Legislature from enacting a measure
legalizing abortion. It was so clear that even the Court cannot interpret it otherwise. This
intent of the Framers was captured in the record of the proceedings of the 1986
Constitutional Commission. Commissioner Bernardo Villegas, the principal proponent of the
protection of the unborn from conception, explained:
The intention .. .is to make sure that there would be no pro-abortion laws ever passed by
Congress or any pro-abortion decision passed by the Supreme Court.169
A reading of the RH Law would show that it is in line with this intent and actually proscribes
abortion. While the Court has opted not to make any determination, at this stage, when life
