The Governor of this State may also surrender on demand of the Executive Authority of any other State any person in this State who is charged in the manner provided in Section 23 of this Act with having violated the laws of the State whose Executive Authority is making the demand, even though such person left the demanding State involuntarily.
The officer or agent of a demanding State to whom a prisoner may have been delivered following extradition proceedings in another State, or to whom a prisoner may have been delivered after waiving extradition in such other State, and who is passing through this State with such a prisoner for the purpose of immediately returning such prisoner to the demanding State may, when necessary, confine the prisoner in the jail of any county or city through which he may pass; and the keeper of such jail must receive and safely keep the prisoner until the officer or agent having charge of him is ready to proceed on his route, such officer or agent, however, being chargeable with the expense of keeping; provided, however, that such officer or agent shall produce and show to the keeper of such jail satisfactory written evidence of the fact that he is actually transporting such prisoner to the demanding State after a requisition by the Executive Authority of such demanding State. Such prisoner shall not be entitled to demand a new requisition while in this State.
If and when such consent has been duly executed it shall forthwith be forwarded to the office of the Governor of this State and filed therein. The judge or justice of the peace shall direct the officer having such person in custody to deliver forthwith such person to the duly accredited agent or agents of the demanding State, and shall deliver or cause to be delivered to such agent or agents a copy of such consent; provided, however, that nothing in this section shall be deemed to limit the rights of the accused person to return voluntarily and without formality to the demanding State, nor shall this waiver procedure be deemed to be an exclusive procedure or to limit the powers, rights or duties of the officers of the demanding State or of this State.
