Jason L. Cassidy


Legal Assistant: Tina Kaminski


Jason is a member of the firm’s Litigation and Cybersecurity practice groups. He focuses on helping businesses solve their problems, with an eye toward heading off litigation before it develops. In particular, he offers his services to video game developers across the country to assist with the challenges facing that industry. 

Jason’s broad experience has given him insight into the wide array of issues facing businesses, with a particular attention to contract disputes and interpretation. He practices in state and federal court and has experience helping clients resolve disputes involving data security breaches, defamation, contract interpretation, water rights, infrastructure and utilities, the False Claims Act, real estate, land use/zoning, discrimination, ADA/disability issues, bankruptcy, and a variety of other business issues. 
Some of Jason’s representative matters include: 

  • Representing an Irrigation District in federal court litigation against a public utility involving the interpretation of a 100-year-old contract and the water rights to supply a large swath of the West Valley.
  • Leading a junior associate through research in compliance with multiple state environmental and manufacturing requirements for a multi-billion dollar international company planning a U.S. launch of an innovative combination product.
  • Assisting a multistate electrical transmission project in ongoing compliance with state and federal environmental laws.
  • Negotiating a full-discharge settlement of a client’s student loans from the United States via an adversary bankruptcy proceeding. Jason was named to the Arizona Pro Bono Honor Roll in 2014 by the Arizona Bankruptcy Court for his work on this case.
  • Defending a group of healthcare workers in three related defamation actions involving the Federal Tort Claims Act, tribal law jurisdiction, and arguments of first impression regarding acts within the scope of employment.
  • Defending a national grocery store chain in a series of five lawsuits that sought to stop construction and operation of a new store in Surprise, Arizona. The store is now open for business.
  • Obtaining an injunction against the United States to save a business from being shut down by an arbitrary agency determination.
  • Obtaining a long-term restraining order against a university on behalf of a graduate student facing expulsion that would have violated the ADA and Rehabilitation Act.

As an undergrad, Jason studied music at Northwestern University. After graduating, he became a stage actor in Chicago and appeared in many musical theatre productions in the area. He spent nine months traveling the country in a tour bus and has performed on stages from New York to Hawaii. 

In addition to his music/acting career, Jason spent eight years as a legal assistant. Before attending Northwestern Law, Jason assisted attorneys with a wide variety of cases involving civil litigation, real estate, estate planning, state and federal regulatory matters, and loan transactions. 

At Northwestern Law, Jason was a member of the Accelerated J.D. program, completing three years of coursework in only two years. He graduated cum laude and was named an inaugural Kirkland & Ellis Scholar for his academic achievements.
