Does a moot claim have to be adjudicated on the merits of an appeal?

There are three discretionary exceptions to the rule against adjudicating moot claims. A reviewing court may decide an appeal on the merits "(1) when the case presents an issue of broad public interest that is likely to recur [citation]; (2) when there may be a recurrence of the controversy between the parties [citation]; and (3) when a material question remains for the court's determination [citation]." (Cucamongans United for Reasonable Expansion v. City of Rancho Cucamonga, supra, 82 Cal.App.4th at pp. 479-480.)
