Okla. Const. art. II, § 24

Private property shall not be taken or damaged for public use without just compensation. Just compensation shall mean the value of the property taken, and in addition, any injury to any part of the property not taken. Any special and direct benefits to the part of the property not taken may be offset only against any injury to the property not taken. Such compensation shall be ascertained by a board of commissioners of not less than three freeholders, in such manner as may be prescribed by law. Provided however, in no case shall the owner be required to make any payments should the benefits be judged to exceed damages. The commissioners shall not be appointed by any judge or court without reasonable notice having been served upon all parties in interest. The commissioners shall be selected from the regular jury list of names prepared and made as the Legislature shall provide. Any party aggrieved shall have the right of appeal, without bond, and trial by jury in a court of record. Until the compensation shall be paid to the owner, or into court for the owner, the property shall not be disturbed, or the proprietary rights of the owner divested. When possession is taken of property condemned for any public use, the owner shall be entitled to the immediate receipt of the compensation awarded, without prejudice to the right of either party to prosecute further proceedings for the judicial determination of the sufficiency or insufficiency of such compensation. The fee of land taken by common carriers for right of way, without the consent of the owner, shall remain in such owner subject only to the use for which it is taken. In all cases of condemnation of private property for public or private use, the determination of the character of the use shall be a judicial question.
