Article XI
Section 8

The right of eminent domain shall never be abridged, nor so construed
as to prevent the legislature from taking the property and franchises of incorporated
companies, and subjecting them to public use, the same as the property of
individuals; and the police powers of the state shall never be abridged or so
construed as to permit corporations to conduct their business in such manner as to
infringe the equal rights of individuals, or the general well being of the state.
