She focuses her practice on government and securities regulatory investigations, financial services litigation, commercial litigation, and corporate compliance. Drawing on her experience in government service and private practice, Ghillaine regularly represents corporations and individuals in investigations conducted by the Securities & Exchange Commission, the Department of Justice, the Financial Industry Regulatory Authority, and other government and regulatory agencies.

In Sztrom v. SEC, the U.S. District Court for the District of Columbia confirmed that the U.S. Supreme Court’s 2024 decision in SEC v. Jarkesy, which curtailed the Securities and Exchange Commission’s (SEC) ability to seek civil penalties in its administrative forum, does not eliminate the agency’s long-standing ability to pursue industry bars through administrative follow-on proceedings. The opinion underscores that, even after Jarkesy and other recent limits on agency power, the SEC may still use its in-house process to determine whether to bar previously enjoined defendants from the securities industry, with independent review limited to the courts of appeals.

On March 11, the Securities and Exchange Commission (SEC) and Commodity Futures Trading Commission (CFTC) signed a memorandum of understanding (MOU) that both agencies describe as “historic.” The MOU is intended to reset the relationship between the agencies by reducing turf battles, avoiding duplicative regulation, and providing clearer, technology-neutral oversight — particularly in markets where securities and derivatives regimes overlap, including crypto. While it does not change either agency’s statutory authority, it creates a formal framework for coordination that will materially affect how policy, examinations, and enforcement play out in practice.

Today, the Securities and Exchange Commission’s (SEC) Division of Enforcement announced significant updates to its Enforcement Manual, the first comprehensive revision since 2017. These changes, which will now be reviewed annually, are designed to promote greater fairness, transparency, and efficiency in SEC investigations and enforcement actions.

The Financial Industry Regulatory Authority (FINRA) has proposed a sweeping update to how broker‑dealers handle outside business activities and private securities transactions. FINRA seeks to consolidate and replace Rules 3270 (Outside Business Activities of Registered Persons) and 3280 (Private Securities Transactions of an Associated Person) with a single new rule: Rule 3290 (Outside Activities Requirements). The proposal preserves the core investor protection concepts of the existing rules but refocuses them on investment‑related activities.

On January 9, the U.S. Supreme Court granted certiorari in Ongkaruck Sripetch v. U.S. Securities and Exchange Commission (SEC). The case arises out of an SEC civil enforcement action in the Ninth Circuit and squarely presents an important remedial question that the Court left open in Liu v. SEC, i.e., what counts as a “victim” for purposes of SEC disgorgement, and does the SEC have to show that investors actually lost money before it can obtain that relief?

In the final episode of our special 12 Days of Regulatory Insights podcast series, Regulatory Oversight co-host Stephen Piepgrass sits down with Partner Ghillaine Reid — co-leader of the firm’s securities investigations and enforcement team and a former SEC New York Regional Office branch chief and staff attorney — to assess how shifts in SEC leadership and composition are reshaping rulemaking and enforcement.

On March 31, a New York federal court dismissed a proposed securities class-action lawsuit filed against Binance, the world’s largest cryptocurrency exchange. The lawsuit, one of a host of similar actions brought against cryptocurrency exchanges in 2020, was filed by token buyers who purchased cryptocurrency on Binance’s platform.

The plaintiffs asserted that Binance had violated
