Juliette Vani
Available in: English Français
Juliette’s practice focuses on the appellate process. She is principally interested in public law, constitutional law, criminal law, Quebec procedural law, and rights protected by the Canadian Charter of Rights and Freedoms.

Juliette offers consultations to lawyers who are set to appear before the Court of Appeal of Quebec or the Supreme Court of Canada and want to adapt their approach accordingly. She also offers a service drafting motions, applications, and appellate factums.

Juliette has clerked at the Court of Appeal of Quebec in Montreal and at the Supreme Court of Canada for the then Chief Justice Beverley McLachlin. Equipped with four years of experience as a clerk in Canada’s most senior courts, Juliette brings to her clients a capacity to see legal questions from the perspective of the bench and to identify the legal consequences that result from particular decisions. This allows her to advise her clients strategically about their situation and to maximise their chances of success.

Juliette’s experience has provided her with strong instincts regarding the arguments liable to convince judges, the strength of evidence, and the most compelling way of presenting it. She wrote her master’s thesis on the connections between the case constructed by the parties at trial and the decision-making process leading to the judgment. Her master’s thesis won the award of the Association of Law Professors of Quebec and the Themis award. Her thesis was published by Éditions Thémis in 2019 as Une histoire de vérités : perspectives narratives sur le procès criminel (translation: A Story of Truths: Narrative Perspectives on Criminal Trials). Juliette continued her research on the burden of proof and decision-making process at trial and in appeal during two years at the Law Faculty of Oxford University as a recipient of the prestigious Clarendon Scholarship.

Since the new Quebec Code of Civil Procedure in 2016, Juliette co-authors, alongside the Honourable André Rochon, legal commentaries on the articles related to the appellate process in Le Grand Collectif : Code de procédure civile, commentaires et annotations, Éditions Yvon Blais (translation: The Grand Collective: Code of Civil Procedure, Commentaries and Annotations). During the initial years of the new Code, their commentaries were referenced and discussed by the Court of Appeal of Quebec in more than 40 judgments that were pivotal to settling outstanding questions on the new appellate procedure. Each year, Juliette and Vincent Ranger (attorney specialized in civil appeals at the firm Per Curiam) personally analyze all new case law from the Court of Appeal on the appellate process to update Le Grand Collectif.

Juliette is a lecturer at the University of Sherbrooke Law Faculty on appellate procedures.

Before joining Power Law in February 2021, Juliette worked for a year in a well-known criminal defence law firm based in Montreal.

Juliette grew up in Quebec, in the Laurentians and Montreal. She has also lived in Ottawa, the United Kingdom, and France.

Juliette practices law in French and English. She is conversant in Spanish and is learning Italian.
