Gavin J. Rooney is the co-chair of the Lowenstein Sandler Class Action and Derivative Litigation Group.   Mr. Rooney has extensive experience in complex business litigation matters litigated in the federal and state courts of New Jersey, New York, and other jurisdictions.

Much of Mr. Rooney's practice focuses on the defense of large corporate clients sued in class actions.  Mr. Rooney has defended class actions for clients in the public utility, pharmaceutical, and telecommunications industries.  Mr. Rooney’s record of success includes the first-ever decertification of a New Jersey state class action, a ruling exempting public utilities from the reach of the New Jersey Consumer Fraud Act, a decision dismissing a classwide damages model which established New Jersey law on the admissibility of such models, and dismissals of several cases based upon the tariff defenses of public utilities and telecommunication carriers.  At present, Mr. Rooney is counsel to a large, New Jersey-based pharmaceutical company in the defense of several securities and consumer fraud class actions pending in the federal and state courts of New Jersey. 

Additionally, Mr. Rooney also handles non-class securities claims, shareholder disputes, environmental and real estate matters, and other types of commercial litigation.  Mr. Rooney is presently defending a high-profile case against an investment fund that allegedly conspired with a stock analyst to drive down the stock price of a public company, which has been widely reported in the Wall Street Journal, New York Times, and other newspapers. 

Mr. Rooney is also well-experienced in trial and appellate work.   He has tried numerous jury and non-jury cases, and won a jury verdict on behalf of an investment fund plaintiff valued at over $1 million arising out of a public company’s tardy registration of stock.  Mr. Rooney has argued before the mid-level appellate courts of New Jersey and New York on numerous occasions, argued several cases before the New Jersey Supreme Court, and appeared before the Second Circuit Court of Appeals.
