Appellate Advocacy


Success on appeal requires the development and presentation of clear, concise and, of course, persuasive legal arguments. Our litigators possess the unique skills and expertise necessary to achieve this, and to win your appeal. We have successfully argued numerous appeals in a variety of commercial, civil and public law disputes. In addition, we have won a wide range of appellate courts, including the Federal Court on Judicial Review, the Federal Court of Appeal, the Divisional Court, various provincial Courts of Appeal, and the Supreme Court of Canada. Whether in convincing an appellate court to overturn, or uphold, the decision of a lower court or tribunal, the Cavanagh team excels at appellate advocacy.

Supreme Court of Canada Agency

Our team of litigators includes former Supreme Court of Canada clerks and can add value at every step of the appeal process. We assist both lawyers and clients with framing applications for leave to appeal in a way that will attract the Court’s interest. For clients who were successful in the Court of Appeal and are faced with responding to a leave application, we can help convince the Supreme Court that no further appeals are necessary. If a client’s interests are affected by an upcoming appeal, we help them get leave to intervene, so that their perspectives and interests are heard and considered by the Court. Our advice in relation to factum preparation and effective advocacy before the Supreme Court of Canada will give clients confidence that their arguments will have the very best chance of success. From a logistical point of view, our experienced lawyers and paralegals can assist clients from start to finish with quick answers to all sorts of practical questions.
