About Erica

Erica Clausen’s practice focuses on eminent domain, construction, nonprofits, and maritime; she also has broad familiarity with various types of complex civil litigation. Erica has diverse experience representing local, national, and international clients in complicated and often high-profile disputes in state and federal courts. She prides herself in addressing client needs in advance of litigation, including negotiations with various regulatory bodies or governmental entities.

Erica supports Oregon transit authorities, municipalities, utilities, and school districts in their efforts to acquire land through the use of eminent domain. She advises clients on the initial precondemnation process and, if necessary, proceeding with condemnation.

During law school, Erica was a litigation staff member and developed a wealth of knowledge in managing complex litigation, problem-solving with attorneys and staff, and building relationships with clients. Erica’s background also includes externships at law firms in Tokyo, Japan, and Perth, Australia, both of which have enriched her awareness of international legal dynamics and cultures. In 2010, Erica worked as an intern for U.S. Senator Ron Wyden.

Representative Experience

  • Litigation & Dispute Resolution Plus
    • Acting on behalf of both the condemning authority and property owner, Erica has litigated more than a dozen Oregon condemnation actions.

    • Successfully negotiated and contested the U.S. Customs and Border Patrol's seizure of product imported by clients in the cannabis industry.

    • Represented 70 investors who collectively lost nearly $100 million in the Aequitas Ponzi scheme. Obtained favorable settlements with third-party professionals in state court litigation and private arbitration, resulting in a gross recovery exceeding our clients’ investment losses.

    • Successfully challenged the National Women’s Soccer League’s minimum age rule in U.S. District Court as an illegal boycott in violation of federal antitrust law on behalf of 15-year-old professional soccer player Olivia Moultrie. Trial team obtained a temporary restraining order and a preliminary injunction in this landmark case, prohibiting the NWSL and its teams from boycotting Moultrie due to her age. Achievements also included securing favorable rulings on significant questions arising out of federal antitrust and labor law, including that the NWSL and its teams did not constitute a “single entity” for antitrust purposes and that Moultrie’s claim was not precluded by federal labor statutes and did not interfere with ongoing collective bargaining between the NWSL and the NWSL Players Association. Case culminated in the negotiation of a settlement ensuring Moultrie’s right to continue playing in the NWSL, subject to the provisions of any final collective bargaining agreement.
