Contract & Commercial Disputes
Good businesses are built on good contracts. Protecting and enforcing those contracts is critical to success. Tonkon Torp’s trial lawyers know how to protect your contractual rights, and how to avoid impractical and wasteful disputes that can cripple your business.

At Tonkon Torp, we take a businesslike approach to business litigation. We understand that litigation is one tool that can be used to address a broken promise and remedy harm done to a client’s business. When you need to aggressively pursue or defend a lawsuit, we play to win. But we also understand that successful litigation is about achieving your goals without losing focus on business objectives or breaking your budget.

Tonkon Torp Wins Appellate Victory in Auto Insurer Case

Tonkon Torp recently achieved a complete appellate win on behalf of its client, Leif Hansen, in the Ninth Circuit Court of Appeals. In 2018, Tonkon Torp attorneys Steve Olson, Paul Conable, and Meg Houlihan represented Hansen individually and in a proposed class action against his auto insurer, GEICO, for refusing to pay for digital scans of his truck as part of the truck’s repair following a collision. Hansen sued for breach of contract under his insurance policy and breach of the implied covenant of good faith and fair dealing. The federal district court dismissed the complaint for failure to state a claim. That dismissal prompted an appeal to the Ninth Circuit, which was led by Bob Koch and Meg Houlihan.
