Modifies the appointment of members of the Joint Legislative Committee on the Unfunded Liability of the Retiree Health Benefit Fund (Committee), established by this act, providing for five members of the Senate to be appointed by the President Pro Tempore of the Senate, and five members of the House to be appointed by the Speaker of the House (previous edition provided for appointments upon the recommendation of the President Pro Tempore and the Speaker, respectively, with one of those members from each chamber serving as cochair). Provides that the President Pro Tempore and the Speaker are to each designate a member to serve as cochair of the Committee. Adds that members of the Committee serve at the pleasure of the appointing officer and continue to serve until a successor is appointed.  Requires the Committee to meet upon the joint call of the cochairs (previously, required to meet at any time upon the joint call of the cochairs). Establishes that a quorum of the Committee is five voting members. Deletes provision requiring expenses relating to the clerical staff of the Committee be borne by the Committee. Instead adds provisions pertaining to all expenses of the Committee, providing that all expenses of the Committee are to be paid from the Legislative Services Commission's Reserve for Studies. Sets out that individual expenses of Committee members of $5,000 or less, as well as clerical expenses, are to be paid upon the authorization of a cochair of the Committee, and individual member expenses in excess of $5,000 are to be paid upon the written approval of the President Pro Tempore and the Speaker.
