(1) A court, upon filing of a petition for guardianship under this chapter and before the appointment of a plenary or partial guardian, or pending an appeal or action in relation to the appointment, under emergency circumstances and if necessary for the welfare or protection of an individual with a developmental disability, may temporarily exercise the powers of a guardian over an individual with a developmental disability, or may appoint a temporary guardian whose powers and duties shall be specifically enumerated by court order.

    (2) If the court, under subsection (1), exercises the powers of a guardian or appoints a temporary guardian before the appointment of a plenary or partial guardian, a hearing on the petition for guardianship shall be held within 14 days, or at a time fixed under section 614, whichever is earlier.
