On June 30, 2025, the Securities and Exchange Commission’s (SEC) Division of Corporation Finance (the Division) revised two and eliminated one of its Compliance and Disclosure Interpretations (C&DIs) related to the disclosure of environmental proceedings under Item 103 of Regulation S-K.

What Is a Class Action?

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)....Read more

What Is Advertising Litigation?

Advertising litigation is defined as the legal area that covers false or deceptive advertising cases. Lawsuits may be brought by government agencies or corporate competitors based on the Lanham Act—a law that specifically deals with false advertising. The Act outlines how an advertisement can be deemed false. The Federal Trade Commission (FTC) has the ability to file lawsuits to halt deceptive advertising claims. The U.S. Food and Drug Administration may also pursue advertising litigation against violators of government regulations. Companies may be called on to substantiate their advertising claims, whether these are made in print or online....Read more

What Is Removal Law?

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. ...Read more
