Daniel P. Chiplock

Providing Justice for Investors, Consumers, and Injured Individuals

The Chair of the firm’s Securities & Financial Fraud practice group and a senior partner in Lieff Cabraser’s New York office, Daniel Chiplock focuses his practice on financial and consumer fraud cases. Daniel has played an active role in most of the firm’s financial cases over the last two decades, including litigation against Bank of America, McKesson, Qwest, and Tyco, in which he represented both large public pension funds and mutual funds that sustained investment losses in the hundreds of millions of dollars as a result of corporate misconduct. More recently, Daniel led the firm’s multi-year investigation and litigation concerning overcharges in custodial foreign currency exchange (FX) transactions by banks such as BNY Mellon and State Street.  Of Daniel’s and co-counsel’s efforts In the BNY Mellon litigation, which resulted in more than $500 million in recoveries for pension funds and other custodial customers, Judge Lewis A. Kaplan stated: “This really was an extraordinary case in which plaintiff’s counsel performed…an extraordinary service… They did a wonderful job in this case. . . . This was an outrageous wrong committed … and plaintiffs’ counsel deserve a world of credit for taking it on, for running the risk, for financing it and doing a great job.”

Daniel has also been heavily involved in several shareholder derivative lawsuits led by the firm, including cases against Broadcom and Cablevision for backdating stock options awards to company executives.  On the consumer front, Daniel has represented New York consumers overcharged by deceptive trade practices by Microsoft Corporation, as well as customers victimized by the practice of numerous national banks of reordering check payments in order to charge excessive overdraft fees.

Daniel is also active in the firm’s SEC Whistleblower practice, currently overseeing several large confidential filings before the SEC.

Earlier in his career, Daniel represented patients who suffered heart attacks or strokes, and the families of loved ones who died, after having being prescribed the arthritis and pain medication Vioxx. Daniel also successfully represented several individuals who sustained life-threatening injuries as a result of ingesting the Fen-Phen diet drug combination.

On a pro bono basis, as part of Trial Lawyers Care (a project of the American Association for Justice), Daniel represented several individuals, including an injured firefighter, in appeal hearings before the September 11th Victim Compensation Fund. In one case, Daniel’s advocacy resulted in an award that was more than 50 times greater than that which was determined prior to his client’s appeal.

Also on a pro bono basis, Daniel has authored and/or coordinated numerous amicus briefs in cases on appeal before the United States Supreme Court and various Courts of Appeal on issues of particular concern to investors, securities regulators, and campaign finance reform advocates.  Daniel’s amicus briefs have been endorsed and co-signed by numerous U.S. Senators and former SEC Commissioners and officials.

Daniel has served on the Executive Committee of the National Association of Shareholder and Consumer Attorneys, and is an active member of numerous other professional organizations, including Public Justice, the American Association for Justice, and the American Constitution Society for Law & Policy.

In 2021, Daniel won a Certificate of Recognition from the American Association for Justice. The rarely-given award acknowledges AAJ members who have made important and unique contributions to the organization through membership, education, leadership, and/or fundraising to sustain and strengthen the AAJ.
