Any person arrested in this state charged with having committed any crime in another state or alleged to have escaped from confinement, or broken the terms of his bail, probation or parole may waive the issuance and service of the warrant provided for in sections 54-163 and 54-164 and all other procedure incidental to extradition proceedings, by executing or subscribing in the presence of a judge of any court having criminal jurisdiction within this state a writing which states that he consents to return to the demanding state; provided, before such waiver is executed or subscribed by such person, such judge shall inform such person of his rights to the issuance or service of a warrant of extradition and to obtain a writ of habeas corpus as provided in § 54-166. If and when such consent has been executed, it shall forthwith be forwarded to the office of the Governor of this state and filed therein. The judge 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 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.
