For all practical purposes, it is as if the notice of appeal never existed. The rule does not require that the order disposing of the last pending post-trial motion be disposed of on its merits, and it requires that the prior notice of appeal be withdrawn. Once the post-trial motion was filed, plaintiff's prior notice of appeal became ineffective. Lastly, we consider defendants' notice of cross-appeal filed on September 20, 1996. As such, even though defendants' are cross-appealing, the basis of the appeal is independent of the basis of the plaintiff's flawed appeal, and was timely filed.
Defendants appeal from three orders of the trial court.
Supreme Court Rule 341 requires an appellant, or in this case a cross-appellant, to provide citations to relevant authority supporting arguments advanced on appeal. 245 Ill. App. 221 Ill. App. We therefore dismiss defendants' cross-appeal based on their failure to comply with Supreme Court Rules 341 and 343. For the reasons stated, we dismiss plaintiff's appeal for lack of jurisdiction, and defendants' cross-appeal for failure to comply with Supreme Court Rules.
