To protect infants who are born alive. Aug. 5, 2002
"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."
