Representative Matters

Complex Commercial Litigation

  • Defended retailer GNC against significant claims brought by the State of Oregon under the Oregon Unfair Trade Practices Act and Federal Food, Drug, and Cosmetic Act, based on sales of dietary supplements in Oregon.
  • Following a seven-week jury trial, secured a complete victory for XPO, fka Con-way, an American multinational freight transportation company. At issue was the question of responsibility for some portion of defense and indemnity costs associated with three Superfund sites, including the Portland Harbor, and over 1,500 asbestos lawsuits.
  • Defended SVC, a subsidiary of PepsiCo Americas Beverages, in a $105,000,000 breach of contract action filed by the City of Albany after SVC terminated a development agreement pursuant to which SVC was to build a Gatorade plant in Albany, Oregon.
  • Represented Columbia Helicopters in a dispute over Boeing’s refusal to sell Boeing helicopter parts to Oregon-based Columbia Helicopters, to allow Columbia to fulfill its contracts to repair Boeing-manufactured military CH-47 Chinook helicopters. To resolve threatened antitrust litigation, Boeing ultimately agreed to recognize Columbia Helicopters as an independent service organization and provide Columbia with Boeing parts to perform CH-47 repair services.

Product Liability & Torts

  • Defended a national product manufacturer, its parent company, and a national online retailer against product liability claims of approximately $100 million, with parties and witnesses spanning 10 U.S. jurisdictions and three countries. Ultimately resolved the matter for a small fraction of claimed damages.
  • Defended a national wearable device manufacturer against claims that one of its products was dangerously defective. Following a multi-day arbitration, received a complete defense victory. 
  • Defended a product manufacturer in Washington State in multiple cases against claims that its product was dangerously defective, leading to favorable settlements.
  • Oversaw and managed asbestos claims brought against multiple clients, working cooperatively with appointed insurance defense counsel.
  • Tried to a jury verdict Oregon’s first “trespass to produce” claim on behalf of a commercial dairy farm, resulting in clarifying Oregon’s timber trespass statutory scheme.

Shareholder & Corporate Disputes

  • Assisted a company in redeeming its former CEO’s shares after a dispute over valuation by leveraging Oregon’s dissenters’ rights statutes and petitioning the court for a judicial appraisal, resulting in a reasonable parting of ways.
  • Following a two-week jury trial in Central Oregon, protected the majority owners of a manufacturing company from a minority shareholder who refused to redeem minority shares under a shareholder agreement, resulting in an award to our clients of specific performance, a new share valuation, and significant attorney fees.
  • Helped a majority member of an LLC wrest back control of a large recycling outfit after a minority member took illegitimate steps to lock the majority member out of the business. We helped by finalizing an unfinished business transaction and cleaning up corporate record-keeping prior to arbitration.

Consumer Protection

  • Brought claims on behalf of an individual consumer in a successful federal lawsuit against a large credit card company for unlawful practices under the Fair Credit Billing Act and Unlawful Debt Collection Practices Act. Following a federal jury trial, successfully appealed statutory claims to the Ninth Circuit, leading to a favorable settlement.
  • Defended multiple national companies in consumer protection matters instigated by the State of Oregon, including claims under the Oregon Unfair Trade Practices Act and the Federal Food, Drug, and Cosmetic Act.

Other Trial Experience

  • Defended regional hospital system against safety whistle-blower and wrongful discharge claims in a two-week jury trial in southern Oregon, establishing a high bar for the establishment of employer liability under the “cat’s paw” legal theory.
  • Defended business owner against breach of contract claims relating to the sale of a sports-bar business in a one-week jury trial.
  • Represented a secured creditor against guarantors of multi-million dollar promissory notes in a week-long jury trial in Oregon state court, securing a large judgment and attorney fee award for our client.

The Ramos Project

In April 2020, the U.S. Supreme Court struck down non-unanimous jury convictions in criminal cases in Ramos v. Louisiana. A shameful carryover from the Jim Crow era, Louisiana and Oregon were the last two states that allowed non-unanimous criminal convictions when as many as two jurors believed a defendant was innocent. Overnight, more than 260 cases in Oregon became eligible to seek post-conviction relief for unconstitutional non-unanimous convictions. Housed in the Criminal Justice Reform Clinic (CJRC) at Lewis & Clark Law School, the Ramos Project is a statewide pro-bono initiative providing legal assistance to those seeking redress.
