Corporate 'Personhood'

This is the text of the 1886 Supreme Court decision granting corporations the same rights as living persons under the Fourteenth Amendment to the Constitution. Quoting from David Korten's The Post-Corporate World, Life After Capitalism (pp.185-6):

In 1886, . . . in the case of Santa Clara County v. Southern Pacific Railroad Company, the U.S. Supreme Court decided that a private corporation is a person and entitled to the legal rights and protections the Constitutions affords to any person. Because the Constitution makes no mention of corporations, it is a fairly clear case of the Court's taking it upon itself to rewrite the Constitution.
Far more remarkable, however, is that the doctrine of corporate personhood, which subsequently became a cornerstone of corporate law, was introduced into this 1886 decision without argument. According to the official case record, Supreme Court Justice Morrison Remick Waite simply pronounced before the beginning of arguement in the case of Santa Clara County v. Southern Pacific Railroad Company that

The court does not wish to hear argument on the question whether the provision in the Fourteenth Amendment to the Constitution, which forbids a State to deny to any person within its jurisdiction the equal protection of the laws, applies to these corporations. We are all of opinion that it does.
