Jack Aiello led Gunster’s Appellate practice for more than two decades. Board certified in appellate practice since 2001, Jack is involved in appeals in all of Florida’s District Courts of Appeals, the Florida Supreme Court and the federal court system, including the Eleventh Circuit Court of Appeals and the United States Supreme Court.

Currently beginning his fourth decade of practice, Jack’s broad appellate experience extends to litigation support, including preservation of the record for appeals and consultation about the cost and benefit strategy considerations in taking and defending both non-final and final appeals. In addition, Jack is retained to take on appeals brought to Gunster after another firm has previously litigated the case in trial court proceedings. However the matter comes to Jack, after a judgment is rendered, a decision to appeal must be considered. Jack advises clients on how likely the court is to reverse a trial court decision and on what grounds. His assessment of the claim is based on both case law and his decades of experience in appellate related work.

Jack also files amicus curiae briefs in matters that are highly relevant to Gunster’s clients. Such briefs, filed at the District Court or Supreme Court level, can impact or change legal policy and thereby alter the landscape of business throughout Florida. Additionally, Jack handles petitions for extraordinary writs to seek appellate examination of trial court orders that are not otherwise appealable.

Jack is dedicated to working with his clients to define or redefine the parameters of the law through the appeals process. Because appellate law is, by nature, more academic than traditional litigation, Jack analyzes every possible and reasonable legal theory in order to devise the best possible appellate strategy. He is personally committed to being responsive to his clients, as well as to communicating directly and candidly about their options and chances of success on appeal. Jack’s writing skills have been developed over decades of practice, and are supported by equally well-developed oral advocacy abilities.

In the appellate law community, Jack has served as a past chair of the Florida Bar’s Appellate Practice Section, and has also chaired numerous other local and statewide appellate practice committees. He is frequently invited to speak on appellate related topics, including preservation of the record for appeal.
