Appellate, Administrative, Regulatory Attorney

Jim Mountain’s law practice focuses on appellate law and administrative regulatory law. He routinely defends clients against government regulation, sanctions, and assessments.

In appellate matters, Jim represents clients before the supreme courts and courts of appeal of the United States, the State of Oregon, and the State of Washington. With over 40 years of experience, Jim has briefed and argued hundreds of appellate cases.

Jim regularly provides appellate consulting services to other lawyers, in-house counsel, and their clients, including assistance with their preparation of written briefs and oral arguments. He is also available to assist trial attorneys before and during litigation in order to position and preserve critical matters for possible appeal.

Jim also represents his clients’ business, professional, and personal interests before the various administrative agencies and trial courts of the federal, state, and local governments. This representation includes the defense of licensed professionals—doctors, pharmacists, psychologists, architects, geologists, accountants, lawyers, and even judges – in proceedings before their licensing boards or regulatory bodies and, particularly, in the appellate courts. He also represents clients in public records litigation, insurance coverage cases, and government ethics and election matters.

Before joining the firm, Jim served as the State of Oregon’s chief appellate lawyer, its Solicitor General. He also held the number two job in the Oregon Department of Justice as the Deputy Attorney General with responsibility to manage one of the state’s largest law firms.

How I Serve Clients

I am passionate about appellate advocacy, principally in presenting oral arguments to panels of appellate judges to explain why my client’s position should prevail, but also in developing the client’s legal position in written arguments in appellate briefs.

I also welcome opportunities to work with attorneys from other firms at the appellate stage to help their clients obtain favorable rulings and results. Through more than 40 years of practice, I’ve had the tremendous opportunity to make a difference in the lives of Oregon residents through public service and in private practice, and also to help businesses and other organization advance their objectives.
