Securities & Financial Services Litigation & Enforcement


For over 35 years, major multi-national and regional institutions have trusted our securities and financial services attorneys to represent them in state and federal court litigation, FINRA arbitrations, CFPB proceedings and other matters around the world.

No business welcomes conflict. But when disputes do arise, our litigators know how to try–and how to win–cases. We excel at litigating and resolving complex, challenging cases. 

Our trial lawyers include former state and federal judges, U.S. Attorneys, SEC trial counsel, a solicitor general and several fellows of the American College of Trial Lawyers. This direct experience with the workings of the U.S. judicial and regulatory system provides our clients with a rich understanding of the best avenues to explore in resolving disputes. 

Our litigators have collectively tried hundreds of matters, and their successes have been noticed. U.S. News – Best Lawyers, 2010-2019, (Woodward White, Inc.) ranked us as a Tier 1 firm for both our national Securities and Commercial Litigation practices.

Representative Clients
Our clients come from a wide range of industries, including leaders in financial services, health care and life sciences, energy, agribusiness and technology, as well as major non-profit and government entities. 

Our clients include public and private companies, their officers and directors, national and regional banks, broker-dealers, financial advisors, CFPB "covered persons," accounting firms and municipal issuers. We also have experience representing shareholders and bondholders. Our scope is global: we have represented clients around the world. Our focus is local: our extensive experience with courts and regulators give us unique insights into the mindset of decision makers.

Representative Matters

Shareholder Class Action and Derivative Suits 

  • Represented the executive officers and directors of a major U. S. bank being sued personally by a shareholder alleging that they breached their duties of care and loyalty. We convinced the court to dismiss the complaint with prejudice. 
  • Defended an outside director in significant shareholder litigation. Plaintiff alleged breach of fiduciary duty and aiding and abetting breach of fiduciary duty. Case was dismissed without prejudice and plaintiffs’ subsequent effort to amend their complaint was denied. 
  • Defended a large multi-national medical device manufacturer and its current and former directors from shareholder derivative lawsuit. Case dismissed because shareholder failed to show that making a demand for action to the Board would have been futile. 
  • Represented a large human capital management firm against shareholder suit alleging improper manipulation of its financial results following numerous restatements of its financial statements. Complaint dismissed and leave to amend denied. 
  • Defended restaurant chain and certain of its directors against consolidated shareholder class actions alleging breaches of fiduciary dealing and unfair dealings in connection with its merger with dining and gaming company. Case dismissed with prejudice. 
  • Represented a defendant in multi-district putative class action. Matter involved municipal bond issuing municipalities and allegations of claims of conspiracy to rig bids for municipal derivatives in violation of the Sherman Act. Matter resolved on terms favorable to our client. 
  • Represented one of the largest shoe manufacturers in China against shareholder derivative action against its former CEO and his son alleging that the company had published fraudulent financial statements. Plaintiff voluntarily dismissed its complaint following oral arguments on our motion to dismiss. 

Government Investigations and Proceedings 

  • Represented a globally-ranked investment company in numerous related investigations. Several investigations were brought by the Office of Thrift Supervision, the NASD, the SEC and the Attorney General for the State of New York. Allegations included claims of late day trading and market timing of mutual fund shares. After an internal investigation, we obtained a very favorable settlement with the OTS without any repercussions for our client’s officers or directors and convinced the NASD, the SEC, and the State of New York to cede to the jurisdiction of the OTC. When our client was sued for damages in a multidistrict, consolidated class action, we obtained a dismissal of the complaint with prejudice. 
  • Defended a high-profile CFO in a securities enforcement action. This investigation involved 10b-5 and other claims. We achieved a hung jury following a month-long trial and a favorable settlement of all claims without the CFO making any monetary payments.
  • Represented a large public company in connection with an SEC investigation following a financial restatement. After a three-year investigation and 25 days of testimony, we convinced the SEC to drop the matter.
  • Represented a national brokerage firm and investment bank for accused of mishandling client accounts. A state Commissioner of Securities sought extensive fines. After an internal investigation, we successfully negotiated with the State and achieved a very favorable settlement.

M&A Related Litigation 

  • Represented seller of a worldwide pharmaceutical business against claims by the buyer of the business that our client had breached various representations and warranties in the purchase agreement and otherwise defrauded it. Buyer sought damages in excess of $200 million. Following a bench trial, trial judge ruled in favor of our client and plaintiff received nothing.
  • Represented the world’s largest medical device manufacturer in connection with its merger with a Dublin-based health care supplier. Challenges to the transaction were filed in both federal and Minnesota state court with claims that directors breached their fiduciary duties, the disclosures were inadequate and corporate law was violated. We convinced judges in both state and federal court to deny plaintiffs’ motions to enjoin the deal, allowing it to be put to a shareholder vote. Our client’s shareholders voted overwhelmingly in favor of the deal and the transaction was consummated as planned. 
  • Represented a software technology and cloud computing company in a putative class action seeking to enjoin its merger with a major international corporation. We successfully derailed plaintiffs’ efforts to enjoin the acquisition and won a dismissal of their complaint. 
  • Represented a Vancouver-based gold mining company on a federal Williams Act claim brought in federal court in Anchorage. This was part of our client’s successful strategy to fend off a hostile acquisition attempt by the world’s largest gold mining company.

  • Represented a publicly held technology business in connection with its $1.5 billion sale to Oracle. Successfully defended four class action lawsuits brought in connection with the proposed transaction and transaction closed as planned. Plaintiff’s subsequent complaint seeking damages was dismissed with prejudice. 
  • Represented publicly-held publishing company engaging in merger with software developer against two purported class action lawsuits seeking to enjoin stockholder vote on transaction because of alleged deficiencies in proxy materials. Motion to enjoin denied with the Court commenting that some of the plaintiff’s claims “border[ed] on the frivolous.” 
  • Represented publicly-held acquirer against putative class actions seeking to unwind acquisition and hold another shareholder vote. Plaintiff voluntarily dismissed case with prejudice shortly before the hearing on our motion to dismiss. 

Broker-Dealer Arbitration and Litigation

  • Represented a revenue development company in litigation and an eight-week jury trial involving RICO violations and accounting malpractice. Claims also involved fraud and conversion. The jury returned a very favorable verdict for our client, entirely dismissing the RICO and accounting malpractice claims.   
  • Defended the financial planning business of large broker-dealer. Allegations of forgery and securities fraud were made. We won the case on a motion to dismiss. The opinion was the first to expressly recognize that the FINRA rules do not apply when a corporation is acting as a financial advisor and not as a broker-dealer. 
  • Represented large financial planning firm in a FINRA arbitration against claims that the financial advisor recommended inappropriate investments and failed to perform sufficient due diligence of a fund sponsor. Claims were dismissed with prejudice. Defended national financial advisor in a FINRA arbitration commenced by former franchisee. Following a week-long arbitration proceeding, the former franchisee’s claims were dismissed in their entirety.
