Representative Matters

  • Breach of Contract/Fraud Allegations: McKinzie v. Roemer (Alameda County Superior Court). Represented purchaser of Oakland dental practice in action against seller for breach of contract, breach of implied covenant of good faith and fair dealing, and fraud. Resulted in jury verdict for the plaintiff and successful recovery of contractual attorney's fees. Affirmed on appeal.
  • Breach of Fiduciary Duty: PAI Corporation v. Integrated Science Solutions, Inc. (USDC, Northern District of CA). Represented defendants in breach of fiduciary duty and theft of trade secrets case arising out of procurement process for services provided to NASA/Ames resulting in jury verdict for the plaintiff, which was reversed by the trial judge in post-verdict motions. Case settled while pending in Ninth Circuit Court of Appeal.
  • Business Purchase Dispute: Our clients, a husband and wife, purchased a small retail computer business in Silicon Valley. After not experiencing the level of profitability the seller had, our clients investigated and discovered that the previous owner had trafficked in the sale of “remarked” CPUs, an illegal but highly profitable business practice. Our representation of this client involved coordinating investigations by the FBI and Intel’s worldwide fraudulent products division. The case was resolved through binding arbitration, in which we secured a favorable award for our clients.
  • Contract Dispute: Our client rented diesel-powered generators to provide back-up power to a large construction project in Secaucus, New Jersey, run by the Bechtel Corporation. Bechtel refused to pay its bill for additional time that it kept and used our client’s equipment. It counted on its size and market power to prevent our client from recovery of its contract profits. Our client pursued the matter in court and prevailed after a one-week jury trial.
  • Fraud Claims: After assisting in taking Netscape through an initial public offering, our client became the Chief Executive Officer of a start-up company that harnessed the power of the Internet to pair golf enthusiasts with world-caliber golf professionals in analyzing and improving golf swings. Our client entertained the business interests of another local company in the golf industry, but when the business did not succeed, our client was personally sued for fraud. Through a strategic investigation of his accuser, we showed at trial that, in fact, our client had been the victim of a desperate attempt to salvage a dying business, and the plaintiff dropped its case after opening argument.
  • Inverse Condemnation: Burns v. City of Los Altos (Santa Clara Superior Court). Represented homeowners in inverse condemnation action against the city for sewer intrusion resulting in defense verdict. Adverse appeal in Sixth Circuit.
  • Mechanic’s Lien Action: Our clients refused to pay a fencing contractor who installed defective and substandard wrought iron fencing until the work was repaired. The contractor refused to make the repairs and instead recorded a mechanic’s lien against the property and forced the matter to litigation. Through a careful background investigation, we discovered that not only was the mechanic’s lien defective, but the contractor had allowed his contractor’s license to lapse. After a three-day court trial, the court entered judgment against the contractor and awarded substantial damages to our client.
  • Negligence and Inverse Condemnation Defense: McKillop Road in Oakland had a 75-year history of landslides. In 2006, the last portion of the hillside gave way, substantially damaging numerous homes and businesses. These property owners banded together and pursued lawsuits against various public agencies, in which they alleged that improper maintenance of the roadways, sub-surface infrastructure, and a creek at the base of the hillside led to the catastrophe. The City of Oakland retained us to perform extensive testing and discovery, which resulted in the city making a compelling case that the cause of the landslide had nothing to do with the city’s maintenance practices. The city resolved the entire litigation for nominal settlements, while the property owners proceeded to trial against other defendants.
  • Public Contracting Dispute: Our client selected the plaintiff as the low bidder for public works construction. When it was discovered that the plaintiff violated the prevailing wage laws, the plaintiff sued the City of Oakland, claiming that he had been misled into applying the wrong labor rate standards in the bidding process. Due to the nature and extent of the construction work, the case was complicated and required nearly one month of testimony to a jury. At the conclusion of trial, through a carefully crafted simplification of the facts and an explanation of the contracting process, the City of Oakland was found completely free of obligation to the plaintiff’s claims.
  • Rescission Actions: Our client, a life insurance company, was faced with a series of losses arising out of deaths occurring very near in time to the submission of the life insurance application. Investigation revealed that the applicant had failed to provide critical information regarding health and personal habits, which would have resulted in either a denial of their applications, or substantially higher premium rates. In three separate trials, our client elected to present this evidence to a court to establish its entitlement to rescind the life insurance policies. In each of the three cases, our client prevailed.
