Tommy lives in a cage in the town of Gloversville, N.Y. He has filed a petition for a writ of habeas corpus with a state court, asking for release from captivity. But Tommy is a chimpanzee (the petition was filed on his behalf by an animal-rights group), and New York grants the right of habeas review to “persons.”

So Tommy must persuade a judge that he is a person if he is to have his day in court. He and the craft company Hobby Lobby — which operates according to its owners’ Christian convictions and is mounting a religious freedom challenge to the contraception mandate in Obamacare — have become an unlikely pair in an ideologically tinged battle over what a “person” is.

There has been much mockery of the idea that “corporations are people.” But if you think it matters whether the law calls a chimpanzee, corporation or even human zygote a “person,” you are making a fundamental error about how the law works.

From a legal standpoint, there is nothing remarkable about a chimpanzee claiming to be a person. A number of cases have been brought by animals seeking to enforce their rights under the Endangered Species Act, under a provision that gives “persons” the right to bring suit.

In none of these cases was a judge fooled into thinking that an animal possesses all the rights of human beings. The lawyers bringing them were simply ensuring that a judicial remedy was available to address the harm that Congress sought to fix. If the spotted owl had also asked for the right to vote, the request would have been denied. A person for one legal purpose is not necessarily a person for another.

The law also treats various nonhuman, nonsentient entities as “persons” for certain legal purposes. Corporations, estates, trusts, partnerships and government entities are often defined this way. Wal-Mart, Illinois and the California Pension Fund can sue, for example, without anyone asking if they have a right to abortion. This transubstantiation of corporations into persons advances some pretty uncontroversial policy goals. If corporations lacked personhood, you couldn’t sue FedEx for crashing a van into your car or Wal-Mart for selling you a defective space heater. You wouldn’t be able to enter into contracts with a corporation at all. Legislatures and courts have been treating corporations like persons for hundreds of years: There is even a general interpretive rule in the law that when Congress says “persons,” it means corporations as well.

Hobby Lobby argues that corporations enjoy the right to free exercise of religion provided by a 1993 law, the Religious Freedom Restoration Act. RFRA protects “persons” from certain religiously burdensome laws and regulations, and Hobby Lobby argues that Congress meant to include corporations under that shield. Hobby Lobby’s opponents do not argue that RFRA doesn’t apply to corporations — they can’t, because it is undisputed that the statute applies to nonprofit corporations like the Catholic Church. The argument instead is that Congress did not intend RFRA to apply to for-profit, commercial corporations. Whoever is right, the answer turns on what Congress intended, not the metaphysics of personal identity.

Dahlia Lithwick (“If everything’s a ‘person,’ humanity gets devalued,” Dec. 6) says that “conferring human attributes such as religious conviction and the capacity for embarrassment on a corporation is dangerous.” But the law already treats corporations as capable of being reckless or negligent; of having intentions, beliefs and states of mind. If it didn’t, it would be impossible to hold a corporation guilty of committing a crime. Of course, judges don’t think that corporations possess mental states. To find a corporation guilty of a crime, they determine if relevant employees had the requisite bad intent, and then attribute it to the corporation as a whole. Far from turning persons into “things,” as Lithwick argues, these laws protect people from corporate wrongdoing and enable them to benefit from the goods and services that only corporations can provide.

What of bills that would deny women the right to abortion by defining one-celled human zygotes as “persons”? If the effect of such a definition is to deprive women of their constitutional rights, then a court should, and will, strike down the law. Legislatures can’t use legal fictions to change physical facts. They would have just as much success disenfranchising women by defining them as chimpanzees.

Speaking of which, Tommy will lose his case. The reason is not that it would be dehumanizing if a legislature chose to include animals in its definition of “persons” for the purpose of asking to be released from captivity. The reason Tommy will lose is that the New York Legislature did not intend to encompass animals within the definition of “person” for filing a habeas petition. If lawmakers had meant to extend the writ of habeas in this way, when that had never been done before, they would have said so.

If Hobby Lobby wins, on the other hand, it will be because courts think that Congress did intend to encompass for-profit corporations within the definition of “person” in providing for religious freedom.

Whatever you make of these outcomes, you don’t have to worry that chimpanzees, craft stores and zygotes will use them to conquer the planet and enslave humanity. The law does not turn something into a person by calling it one.
