(1) Within forty-eight hours after a priority individual or class of individuals gives a consent pursuant to this section to the use or continuation, or the withholding or withdrawal, of life-sustaining treatment and communicates the consent to the patient's attending physician, any individual described in divisions (B)(1) to (5) of this section, except an individual who is not competent to give consent under division (C)(2) of this section, who objects to the application of this section to the patient shall advise the attending physician of the grounds for the objection. If an objection is so communicated to the attending physician, then, within two business days after that communication, the objecting individual shall file a complaint against the priority individual or class of individuals, the patient's attending physician, and the consulting physician associated with the determination that the patient is in a terminal condition or that the patient currently is and for at least the immediately preceding twelve months has been in a permanently unconscious state, in the probate court of the county in which the patient is located for the issuance of an order reversing the consent of the priority individual or class of individuals. If the objecting individual fails to so file a complaint, the individual's objections shall be considered to be void. A probate court in which a complaint is filed in accordance with this division shall conduct a hearing on the complaint after a copy of the complaint and a notice of the hearing have been served upon the defendants. The clerk of the probate court in which the complaint is filed shall cause the complaint and the notice of the hearing to be so served in accordance with the Rules of Civil Procedure, which service shall be made, if possible, within three days after the filing of the complaint. The hearing shall be conducted at the earliest possible time, but no later than the third business day after the service has been completed. Immediately following the hearing, the court shall enter on its journal its determination whether the decision of the priority individual or class of individuals to consent to the use or continuation, or the withholding or withdrawal, of life-sustaining treatment in connection with the patient will be confirmed or reversed.
