  T. John Fitzgibbons

John joined Robie & Matthai in 2014, after nine years practicing as a civil litigator at Sidley Austin LLP. His practice focuses on representing lawyers and law firms in professional liability litigation and attorney disqualification matters. He also has represented Big Four and regional accounting firms and individual accountants in professional malpractice actions, breach of contract actions, and SEC and state regulatory investigations. From those matters, he has developed substantial knowledge of accounting principles and the audit process, something that makes him a strong advocate for his clients..

John also has a sophisticated sense of litigation strategy and business judgment. He has represented a variety of clients in litigation, including financial institutions, sports, media, and entertainment companies, internet-based companies, and other public and privately-held companies. From those cases, he has a broad base of experiences to draw from when defending legal malpractice cases. In counseling clients, he often calls upon his street smarts and business experience. Before entering law school, John spent several years working in management at a large company, where he set sales performance goals, oversaw a budget and controlled expenses, and served customers and referral sources. That business experience often helps him to identify the business implications of litigation developments as well as the sometimes hidden motivations of his clients' adversaries.

John's calm demeanor makes him unflappable even during the most stressful moments in high stakes cases. His creativity, tirelessness, and judgment help him obtain excellent results for his clients.


Favorite Cases

John represented a Big Four accounting firm in litigation with a former audit client. The audit client's new management accused the firm of failing to detect former management's financial misconduct. The audit client had waited years after the misconduct came to light to bring its lawsuit, so discovery focused on both the merits and the statute of limitations defense. The dual effort bore fruit: the trial court granted summary judgment on statute of limitations grounds and awarded attorney's fees for the costs of proving denied requests for admission, and the Court of Appeal affirmed the trial court's rulings in full.

As co-counsel with Public Counsel, John represented a client in a probate dispute over the client's inheritance. Though the client lived throughout his life with a married couple he perceived to be his parents, the couple never formally adopted him. After they both died intestate, their blood relatives evicted him from the couple's home. In probate court, the client argued that under the theory of equitable adoption, he was the couple's sole heir. At trial, the couple's closest friends testified that the couple had held him out as their son throughout their lives. One friend even brought the program from the husband's funeral, which took place while the wife was still alive. The program described the client as the couple's only son. After a two day contested bench trial, the court ruled for John's client and awarded him the entire probate estate.
