Black's Law Dictionary 6th Edition, pg. 791, defines '
person' as follows: "In general usage, a human being (i.e. natural
person), though by statute term may include labor organizations, partnerships, associations, corporations,
legal representatives, trustees, trustees in bankruptcy, or receivers."
However, since this thread is obviously about the definition of a person as it pertains to abortion and the legal status of a fetus, the following law is defititive:
1 U.S. Code § 8 - “Person”, “human being”, “child”, and “individual” as including born-alive infant
(a)
In determining the meaning of any Act of Congress, or of any ruling, regulation, or interpretation of the various administrative bureaus and agencies of the United States, the words “person”, “human being”, “child”, and “individual”, shall include every infant member of the species homo sapiens who is born alive at any stage of development.
(b)
As used in this section, the term “born alive”, with respect to a member of the species homo sapiens, means the complete expulsion or extraction from his or her mother of that member, at any stage of development, who after such expulsion or extraction breathes or has a beating heart, pulsation of the umbilical cord, or definite movement of voluntary muscles, regardless of whether the umbilical cord has been cut, and regardless of whether the expulsion or extraction occurs as a result of natural or induced labor, cesarean section, or induced abortion.
(c)
Nothing in this section shall be construed to affirm, deny, expand, or contract any legal status or legal right applicable to any member of the species homo sapiens at any point prior to being “born alive” as defined in this section.
1 U.S. Code § 8 - “Person”, “human being”, “child”, and “individual” as including born-alive infant
Clearly, an unborn child is not considered a person under the law as far as rights are concerned. Some states define a person to include an unborn child, but only for the purpose of enforcing fetal homicide laws. The fetal homicide laws of the State of Arkansas define "person," to include an unborn child of 12 weeks or more gestation. However these fetal homicide laws do not apply to abortions. Here are the fetal homicide laws in all 50 states:
