Closely related to the issue of appellatejurisdiction is the question of whether there is a case or controversy. This problem is commonly presented by an appeal or petition that initially was within the jurisdiction of the appellatecourt, but that has become moot by the expiration of time or as a result of subsequent events. Cases of this nature remain within the jurisdiction of the court in a technical sense, but they could be dismissed on the ground that the appellatecourt’s decision would have no effect on the litigants. An appellatecourt may retain jurisdiction over an issue that has become moot only in limited circumstances.85
The proper method of asserting a claim of mootness is to file a motion to dismiss. As a practical matter, the mootness of an issue might not be apparent to the appellatecourt if it were not presented by a party’s motion. The event that makes the issuemoot might be a change in circumstances that would not be apparent from anything in the record from the trial court. For this reason, it may be necessary to prepare an appendix to the motion to establish the factual basis for the claim of mootness.
Regarding disobedience of a civil judgment, an appellatecourt may dismiss a criminal appeal if the defendant has become a fugitive and is no longer within the appellatecourt’s control.88 However, this Rule applies only if the defendant absconds after invoking the appellatecourt’s jurisdiction.89 A criminal defendant who becomes a fugitive before the sentencing hearing does not forfeit the right to appeal once he or she is taken back into custody and sentenced.90
Another ground for dismissal is that the proceeding before the appellatecourt is frivolous. This is not often a good basis for a motion to dismiss, given the general legal policy favoring decisions on the merits when possible, and given the fact that it often will be difficult to evaluate the case until the record is filed. After the record is filed, it might be just as easy to affirm the case. There are instances, however, in which appellatecourts have dismissedproceedings on the ground that they were frivolous.91 In Florida,
[a] frivolousappeal is not merely one that is likely to be unsuccessful. It is one that is so readily recognizable as devoid of merit on the face of the record that there is little, if any, prospect whatsoever that it can ever succeed.... It must be one so clearly untenable, or the insufficiency of which is so manifest on a bare inspection of the record..., that its character may be determined without argument or research.92
