Boone Karlberg News

After 34 years of serving in the legal field and 23 years of partnership with Boone Karlberg P.C., Ross Tillman is retiring from the practice of law. Throughout his career, Ross has focused on personal injury litigation, insurance coverage evaluation and litigation, insurance bad faith litigation, and defamation work. In addition to his law practice, Ross has served in the local community as a member of the board of directors for Montana Food Bank Network, volunteered his time at the Missoula Humane Society, and is a licensed foster care provider. Ross also held membership positions within legal organizations such as Montana Defense Trial Lawyers Association and Defense Research Institute. It is never easy to bid farewell. Ross will be deeply missed, and we wish him all the best along with his wife Marta Pierpoint and his two children Matthew Tillman and Rachel Tillman. We are grateful for Ross’s many accomplishments and his legacy, work ethic, and passion will continue to inspire us well into the future.

A Cascade County judge granted Boone Karlberg’s motion to dismiss a lawsuit filed by a private landowner against the City of Great Falls.  The landowner sought compensation for the City’s denial of a request to annex property just outside City limits, which the landowner hoped to develop with the benefit of City zoning and services.  The landowner sought over $4 million from the City of Great Falls. 

Attorneys Zach Franz, Natasha Prinzing Jones, and Evan Coren represented the City of Great Falls. 

In a summary judgment motion, Boone Karlberg noted that Montana law gives cities and towns discretion to grant or deny a request for annexation.  In this case, the City’s denial of the annexation did not change the property owner’s existing rights or the historical use of the property.  Relying on case law from the United States Supreme Court and the Montana Supreme Court, Boone Karlberg argued that denial of annexation is not a “taking” within the meaning of the law.  After written briefs and oral argument, the District Court judge agreed and dismissed the lawsuit. 

We are proud to have represented the City of Great Falls and are pleased with another favorable outcome for Boone Karlberg’s client.  Read the full Order here

A Gallatin County judge granted Boone Karlberg's motion to dismiss all claims against a Belgrade daycare in regard to an infant’s alleged head injury.  

Attorneys Ross Tillman and Zach Franz filed the motion on behalf of the daycare and its owners, whom the plaintiffs alleged were responsible for a 4-month old's subdural bleeding.  Tillman and Franz took the depositions of 10 witnesses, including treating doctors, law enforcement officers, and state daycare licensors.  Their investigation demonstrated a lack of evidence that the daycare caused the child's medical condition, and established the condition may have arisen naturally.  

In their summary judgment motion, Tillman and Franz argued the plaintiffs had not met the legal burden necessary to support their claims.  After written briefs and an in-person hearing, the District Court judge agreed.  

We are proud to have represented the defendants in this case and are pleased with the favorable outcome.  Read the full Order here.
