No, there is no contest between the rights of the mother and the fetus because the fetus is simply incapable of asserting its rights. The root problem is that the fetus cannot speak for itself, so we cannot know its wishes or desires. Instead, the fetus has advocates - its father or grandparents, etc. In the case of disputed abortion, these advocates are in a dispute with the mother, it is the mother who will be coerced if a ruling is in favor of the advocates of the fetus and it is these advocates who will be restrained - by force, if necessary - from coercing the mother to continue the pregnancy if a ruling is in her favor. In this regard, a fetus is in the same position as any other entity on behalf of which people want to advocate, such as an animal. Rothbard says of animal rights (Ethics of Liberty):
“There is, in fact, rough justice in the common quip that “we will
recognize the rights of animals whenever they petition for them.” The
fact that animals can obviously not petition for their “rights” is part of
their nature, and part of the reason why they are clearly not equivalent
to, and do not possess the rights of, human being. And if it be protested
that babies can’t petition either, the reply of course is that babies are future
human adults, whereas animals obviously are not.”
Where I differ with Rothbard is that I think that animals likely would, in fact, have rights in a real natural order legal system for the same reasons that children and, to an extent, unborn fetuses would have rights - people are willing to fight for those rights. If you kick your dog, you are likely to end up in a dispute with someone who thinks you oughtn’t be mistreating the animal that way. The purpose of the law is to resolve disputes without martial contest and, unless this dispute is resolved by violence, it may have to be resolved through the legal system. That is, I may file suit against you for your treatment of your dog, seeking to seize the dog from you. Unlike human offspring, no one has any better claim to advocate for the dog than anyone else so there are no natural limitations on who may sue.
Fetuses and animals are in the same logical category, they are both mute entities. They are, therefore, incapable of participating in legal disputes and their rights, therefore, extend only so far as those who advocate on their behalf are willing to fight for them. To paraphrase Rothbard, “We will recognize the rights of unborn fetuses whenever they petition for them.” But fetuses would likely have rights in a real natural order legal system for precisely the same reason animals would likely have rights. That is, if you go to abort your fetus, you are likely to end up in a dispute with someone who believes you oughtn’t abort the fetus. Unlike in the case of a dog, however, there is a natural division between who has higher and lower claims to advocate for the well-being of the fetus, so not everyone may sue. As I pointed out above, I believe the point of viability would be a crucial dividing line in a natural order legal system.
Clayton -
human being, and is therefore entitled to all of the rights of human beings.
Very good; let us concede, for purposes of the discussion, that fetuses are
human beings-or, more broadly, potential human beings-and are
therefore entitled to full human rights. But what humans, we may ask,
have the right to be coercive parasites within the body of an unwilling
human host? Clearly no born humans have such a right, and therefore, a
fortiori, the fetus can have no such right either.
