Securities, M&A & Corporate Governance Litigation
In today’s market, litigators with experience in securities, corporate governance, and M&A-related (collectively, “securities litigation”) matters need to leverage their broad experience to serve as both advocate and as counsel and strategist, focused on helping clients to overcome not just a legal issue but a collective business problem. Given the frequent interplay between things such as corporate-control transactions, public offerings, activist shareholders, the use of complex derivatives and other financial instruments, bad news impacting stock performance, regulatory inquiries and investigations, and insurance coverage, strategic and tactical litigation decisions can have a wide-ranging impact on the success of a given transaction, as well as on companies, their boards, senior management, and advisors.

Law Glossary
A class action is a procedural device that allows one or more persons, usually plaintiffs (though federal and state procedural rules also authorize defendant classes) to file suit on behalf of a group of similarly situated persons. Federal law defines a class action as “any civil action filed under Rule 23 of the Federal Rules of Civil Procedure or similar State statute or rule of judicial procedure authorizing an action to be brought by 1 or more representative persons as a class action.” 28 U.S.C. § 1332(d)(1)(B), (d)(8).
Law Glossary
Removal is a procedural mechanism through which a case filed in state court may be transferred to federal court upon the request of one or more parties. Actions filed in state court over which a federal court would have original jurisdiction may be transferred—or removed—to federal court under the removal statute, 28 U.S.C. § 1441. Generally speaking, removal is possible if (1) the plaintiff(s) and defendant(s) are citizens of different states and the case places more than $75,000 in controversy (so-called “diversity” jurisdiction), or (2) the case turns on issues of federal law (so-called “federal question” jurisdiction). In many cases, defendants prefer to be in federal court, and so defendants often analyze early in the case whether removal is possible.

Dark patterns are deceptive or manipulative designs on digital platforms that trick users into making unintended choices. Dark patterns can appear as designs that create misleading impressions, hide or delay disclosure of material information, lead to unauthorized charges, or obscure privacy choices. Some examples include advertisements deceptively formatted to look like independent editorial content; non-descriptive dropdowns, arrows, or small icons to hide the full cost and other terms, free trials that automatically convert to recurring subscriptions; and prominent cookie-consent banners that hide cookie-rejection options.
