Where a special district advisory committee consists of voting members representing more than five independent special districts, the advisory committee may appoint an executive committee to undertake all or part of the study and may authorize the executive committee to prepare a tentative report and recommendation for submission to and approval by the full advisory committee. The executive committee shall consist of the number of voting members as the advisory committee may determine. If the commission authorizes the appointment of nonvoting members to the advisory committee, those nonvoting members may appoint members to the executive committee in numbers not exceeding those appointed by the voting members and any nonvoting member appointed to the executive committee shall have all of the rights of a voting member on the committee, except the right to vote.
Upon completion of the studies of the executive committee, the executive committee shall report to the full advisory committee and submit any tentative report and recommendation prepared by the executive committee. Thereafter, the advisory committee may reject any tentative report and recommendation submitted, may adopt any tentative report and recommendation submitted, either as submitted by the executive committee or as changed by the full advisory committee, or the advisory committee may prepare its own report and recommendation.
