John B. Kearney is Managing Partner of the New Jersey office. He is known for his skill in representing clients at trial and in litigation in an array of complex civil cases. He routinely collaborates with other attorneys across the firm's various practice areas to ensure that clients have the most comprehensive resources at their disposal in preparing and trying cases. He also has extensive experience serving as co-counsel with national law firms in complex litigation matters.

Mr. Kearney has represented a wide range of individuals and businesses, including Fortune 500 companies, in various cases. His experience includes:

  • Toxic torts 
  • Environmental litigation 
  • Class actions 
  • Commercial litigation 
  • Product liability 
  • Personal injury, including wrongful death

In addition to his trial experience, Mr. Kearney has extensive experience in alternative dispute resolution, including arbitration and mediation.

Representative Matters  

    • Represented a major oil refiner in a New Jersey state court wrongful death case involving a 24 year old former marine who allegedly died of AML from exposure to benzene found in various products during the course of his military service at Camp Pendleton, California. Mr. Kearney successfully obtained summary judgment on the issues of product identification and proximate cause by showing that the decedent's estate had not carried its burden of proving that jet fuel sold by his client was ever used by the military at Camp Pendleton during the time the decedent was stationed there.
    • Represented a major oil refiner in a federal case involving the deaths of two contractors, who allegedly died of asphyxiation as a result of exposure to nitrogen during the course of their work. The case settled after several days of trial. Sanctions awarded against plaintiffs' counsel for willful misconduct in causing a mistrial were upheld by the Third Circuit.
    • Represented this same client in a state court wrongful death action. The decedent allegedly contracted a form of leukemia known as CLL as a result of exposure to benzene and other toxic substances at various refineries. Mr. Kearney successfully sought the client's removal from the case on summary judgment by showing no link between the onset of the disease and any alleged exposure at the client's refinery. 
    • Obtained summary judgment against a plaintiff who claimed it had an oral contract to buy commercial properties. Plaintiff had been negotiating with the seller over terms of a proposed option, but the seller entered into a written agreement with our client first. On motion, Mr. Kearney convinced the court that there was no enforceable oral contract.
    • Prevailed after a seven-day bench trial in federal court in a shareholder dispute on behalf of a franchisor corporation. The court found that the corporation's oral agreement to repurchase another shareholder's stock for the price he originally paid years ago was enforceable. The court also found in favor of the corporation on all breach of fiduciary duty and financial impropriety counterclaims, and that the defendant's stock had been fully repurchased due to his failure to pay franchise fees.
    • Obtained a seven-figure settlement for a major national bank through the use of a two-day mediation conducted prior to filing suit against the directors and officers of a closely held corporation for breach of fiduciary duty. In so doing, the client was saved both time and money, as expensive litigation was averted and the client recovered funds several years earlier than it could have in litigation.

Pro Bono Experience

Mr. Kearney has represented individuals and groups in various pro bono cases over the course of his career in the state and federal courts.
