Whenever the Chief Justice of the Supreme Court finds that the number of state referees available for the performance of the duties of state referees under subsection (c) of § 13a-73, sections 13a-74 and 13a-76, subsection (d) of § 32-658 and sections 32-659 and 32-660 is not sufficient to consider and act upon the acquisition of land and buildings for a stadium facility and related parking facilities, as defined in § 32-651, with reasonable promptness, said Chief Justice, upon the application of the commissioner or the secretary, as the case may be, may appoint such number of additional state referees as necessary to expedite the performance of such duties. Such appointments may be made from time to time and for such period of time, not more than two months in length, as designated by the Chief Justice. Such additional state referees shall have the same powers and duties as state referees appointed under § 52-434, with respect to the granting of the approvals and the performance of other duties of state referees in the acquisition of land and buildings for such expressway, highway, stadium facility and related parking facilities and shall receive such reasonable compensation as is determined by the Chief Justice, and such compensation and expenses incurred in the conduct of any hearings by such state referees shall be paid as a part of the cost thereof.
