Matthew’s work in State Farm helped establish Arizona law favorable to consumers in insurance disputes. Through that result, insurers were required to pay benefits that otherwise could have been withheld, creating meaningful protection for policyholders and strengthening the rights of injured people statewide in disputed claims. In Webb v. Gittlen, the Arizona Supreme Court again ruled in favor of his client and against the insurance industry. The decision reflected his commitment to using individual cases to improve broader consumer protections, helping clients seek fair treatment while also influencing legal standards affecting Arizona injury victims throughout the state.
