Colorado Constitution Article II Section 14 and Section 15
“Section 14:
Taking Private Property for Private Use
Private property shall not be taken for private use unless by consent of the owner, except for private ways of necessity, and except for reservoirs, drains, flumes or ditches on or across the lands of others, for agricultural, mining, milling, domestic or sanitary purposes.
Section 15:
Taking Property for Public Use Compensation, How Ascertained
Private property shall not be taken or damaged, for public or private use, without just compensation. Such compensation shall be ascertained by a board of commissioners, of not less than three freeholders, or by a jury, when required by the owner of the property, in such manner as may be prescribed by law, and until the same shall be paid to the owner, or into court for the owner, the property shall not be needlessly disturbed, or the proprietary rights of the owner therein divested; and whenever an attempt is made to take private property for a use alleged to be public, the question whether the contemplated use be really public shall be a judicial question, and determined as such without regard to any legislative assertion that the use is public.”
