Casie Collignon has a broad base of experience in both trial and appellate courts in Colorado and around the United States. Casie represents clients in a variety of litigation matters, including class action lawsuits, fiduciary relationships, trust and estates, construction defects, domestic relations and other commercial property and contract disputes.
In her class action practice, Casie has been instrumental in successfully defeating class certification in consumer lawsuits (including a California Unfair Business Practices lawsuit and a Colorado Consumer Protection Act lawsuit), obtaining dismissals of class action claims in a variety of contexts (including an ERISA breach of fiduciary duty lawsuit), developing extensive e-discovery strategies and reaching favorable class and non-class settlements by focusing on creatively limiting client exposure. Casie is the chair of the Class Actions, Derivative Suits and Mass Torts Subsection of the Litigation Section of the Colorado Bar Association, and in 2010 and 2011, was honored as a “Rising Star” in the area of class action and mass torts by Colorado Super Lawyers Magazine.
In her complex business litigation practice, Casie has successfully represented corporations, individuals and other entities in both state and federal courts, including successful appeals to the Colorado Supreme Court and a successful petition for en banc review to the Tenth Circuit Court of Appeals resulting in the published opinion of Hydro Resources, Inc. v. U.S. E.P.A., 608 F.3d 1131 (10th Cir. 2010). As part of this practice, Casie has extensive experience with mediations, arbitrations and special master proceedings resulting in favorable settlements or outcomes for her clients.
Casie approaches all of her clients with a responsive eye toward their individual needs. While zealous representation is often accompanied by aggressive legal strategy, she also believes that there is a time and place for cooperation in most litigation contexts. This approach has led to substantive and economic rewards for her clients.
While in law school, Casie served as the Managing Editor for the Denver University Law Review and received an award for outstanding academic achievement in Legal Ethics. After law school, Casie clerked for the Honorable John Daniel Dailey, Colorado Court of Appeals. During her clerkship, she gained insider experience and familiarity with state appellate and procedural issues.
Casie is a member of the American, Colorado and Denver Bar Associations. She is the former President of the Denver Bar Association’s Young Lawyers Division and is generally active in Denver’s pro bono legal community. In 2007, Casie received the Denver Bar Association’s Award for Volunteer Lawyer of the Year. Currently, she is a co-founding board member of the Denver Urban Debate League, a non-profit that seeks to promote speaking skills and access to education for diverse high school students.
