Areas of Focus

Overview

Joanna Forster’s multifaceted background positions her to effectively manage conflicts across the legal spectrum and across the globe. In her prior roles as general counsel (representing both plaintiffs and defendants) and as government prosecutor/enforcer, Joanna handled nearly every type of matter, ranging from complex commercial and white collar matters in areas such as employment, intellectual property, securities and antitrust law, to internal investigations and corporate and M&A transactions. She views her role as both a conflict manager, dispensing advice to avoid adversarial action, and as a tech and business litigator, resolving disputes with her client’s business goals in mind.

Having served as the general counsel and compliance officer of a publicly traded ecommerce platform operating in over 60 countries, Joanna has an appreciation of strategic dispute resolution, investigations, and compliance from a general counsel’s perspective. By understanding how business leaders combine the input of in-house and outside counsel to make decisions, Joanna is able to provide her clients with decisive and efficient legal guidance.

Her practice includes litigating domestic and cross-border complex commercial disputes and advising technology and ecommerce companies on matters related to internet platforms, product launches, market campaigns, and new vertical lines of business, all while advising on foreign and domestic laws that regulate online content, physical products, and the companies that bring them to market. Drawing on her experience as the General Counsel of an online e-commerce marketplace, Joanna also regularly advises and counsels clients on California’s Proposition 65, from prevention and compliance to remediation. Joanna is well-versed in key regulations that impact ecommerce companies, including the EU’s Digital Services Act, the U.S. INFORM Act, and the proposed SHOP SAFE Act, as well as laws and regulations that govern online speech such as the Communications Decency Act, Section 230.

Prior to going in-house, Joanna was the deputy attorney general, Corporate Fraud Section of the California Department of Justice. In this capacity, she led large, complex civil matters alleging violations of California’s False Claims Act, Securities Law, Section 17200, Cartwright Act, and other deceptive business practices. She also maintained her own investigations and litigation docket.

Before joining the California Department of Justice, Joanna spent nearly a decade in private practice, where she focused on civil and criminal antitrust and commercial litigation. She also served as a law clerk for the Honorable Consuelo B. Marshall in the U.S. District Court for the Central District Court of California.
